Can anyone offer any assistance? My boyfriend's conv. hardtop gets stuck on his 2006 Cadillac XLRV, sometimes up, sometimes down..and sometimes in between. He has taken it in to the dealer several times, some parts have been replaced. But they usually tell him they cannot duplicate the problem. He is quite frustrated, so now it is time for the research queen to see if I can find some answers. Make me a hero, thanks!

This sounds very much like what we are going to hear from now on. I'd like to have a nickel for every, "Can't duplicate". Just keep bringing it in after every time it does it or have them come pick it up when it is stuck up in the air and tell them to duplicate this. The 06 and above are not known for top trouble so I'm a bit surprised. I have an 06-V and knock on wood no problems.

This isn't a terrrrrrribly unusual problem. Many dealers replace (upgrade) the switches that sense the position of the top to potentiometers (though your 06 may already have these). I also hope the dealer has installed the latest version of the software.

It sounds like you're able to get it back down or up before you hit the dealer. Do you do it manually or does the car eventually figure it out?

Standby is correct - the tops on the newer models are relatively trouble free. Even my 04 has only had 1 minor glitch. My glitch is when the latches don't engage or release, the top will hold that position and not continue up or down. I have the wrench handy in case I need to "tickle" a latch or 2. The worst that will happen is that I simply put the top back up or down - it always will return to one position or another. I only have this issue when I leave the top down for extended periods of time (which the manual does NOT recommend), so I always put it back up nowadays. So far, so good. If this sounds like your problem, get familiar with the locations of the latches (and the sounds they make while latching/unlatching) and you can diagnose it yourself. Maybe your hydraulic pump isn't making the pressure it needs to make to do the job correctly. Does the top take unusually long (more than 30 seconds) to open?

Another plan of attack is to take it to another dealer for service. Sometimes another set of eyes or a more experienced technician will know just what to do!

Good luck! I'm sure it will get repaired eventually. Please keep us updated!

More than 30 Sec top

I took mine into the dealer today and they simply said that there was a bulletin for the issue. So no hassles there. My parts are ordered and my car is just sitting pretty. Good luck!

I had a problem only one time, the Tech at my dealer constantly goes to school and does all of the electrical problems and other adjustments on the top. Have not had a problem since he fixed it. Bring it to Colorado Sprngs and James will fix it for you as he did mine. Good luck.

<HR>This bulletin is being revised to add the 2009 model year. Please discard Corporate Bulletin Number 03-08-67-008C (Section 08 -- Body & <NOBR>Accessories</NOBR>).
<HR>This bulletin provides diagnostic information for a power folding top that exhibits the following conditions:
<TABLE border=0><TBODY><TR><TD vAlign=top> • </TD><TD vAlign=top>The power folding top stops mid-cycle.</TD></TR></TBODY></TABLE>

Technicians may find that no Diagnostic Trouble Codes (DTCs) have been set.
<A href="http://gsi.xw.gm.com/si/showDoc.do?docSyskey=2234169&from=sm#ss1-2234169">Diagnostic Information For Intermittent Folding Top Operation

Intermittent concerns with top operation that do not set a DTC can possibly be related to top position sensors that read a position incorrectly. In such cases, the top will operate to a point and will not advance and complete the operation. In these cases, the pump will continue to run up to 15 seconds as long as the top control switch is depressed.
The top operates in a sequence of steps: the first step must be completed before the second step can start. The folding top control module reads the limit switches and position sensors (potentiometers) in order to determine if one step is complete and the next step can begin.
In order for a technician to diagnose a concern, it is important to assess and record the position of the top parameters where the roof stops (the location in the top operation sequence) and is unable to complete the cycle. It is also important to know the direction of operation, moving from top closed (coupe) to top open or moving from top open (convertible) to top closed.
Important: Performing a relearn procedure on the Folding Top Control (FTC) module will reset all of the reference parameters and the top will usually function again but the root cause of the concern will not have been corrected.
<A href="http://gsi.xw.gm.com/si/showDoc.do?docSyskey=2234169&from=sm#ss2-2234169">Sequence for Opening the Folding Top

Before any movement of the folding top toward the open position is allowed, the following conditions must be met or top operation will be inhibited:
<TABLE border=0><TBODY><TR><TD vAlign=top> • </TD><TD vAlign=top>The cargo cover must be pulled or extended into position (Luggage Barrier Limit Switch Closed).</TD></TR></TBODY></TABLE>
<TABLE border=0><TBODY><TR><TD vAlign=top> • </TD><TD vAlign=top>Verify that the hydraulic pump bypass valve at the motor is in the operating position by turning the valve clockwise.</TD></TR></TBODY></TABLE>

To cycle the top from the closed/coupe position to the open/convertible position, press the folding top control switch to the open direction and hold. The folding top status changes to Opening and the following steps will then take place:
  1. <LI type=1>The windows will express open (if closed). <LI type=1>The front tonneau (three piece closure behind the seats) opens. The header latch unlatches. This latch is located in the middle forward area of the roof panel. The deck lid/trunk lid opens. Tip
    If the top operation will not advance past Step 2, it is possible that:
    <TABLE border=0><TBODY><TR><TD vAlign=top> • </TD><TD vAlign=top>The FTC module is not reading the Front Tonneau Position Sensor value at or above the Front Tonneau Open Reference Position Value.</TD></TR></TBODY></TABLE>

    <LI type=1>The top opens (roof retracts into the trunk). Tip
    If the top will not advance past Step 3, it is possible that the FTC module is not reading the Folding Top Position Sensor value at or below the Folding Top Open Reference Position value.
    <LI type=1>The rear tonneau (the retracted panel below the deck lid) extends. Tip
    If the top will not advance past Step 4, it is possible that the FTC module is not reading the Rear Tonneau Position Sensor value at or below the Rear Tonneau Closed Reference Position value.
    <LI type=1>The front tonneau closes. The header latch latches, securing the roof panel with the structure behind the seats. Tip
    If the top operation will not advance past Step 5, it is possible that:

</TD></TR></TBODY></TABLE>Important: Folding top operation that is free from intermittent failures to complete open or closing operations is dependent on consistent readings by the FTC module of the position sensors in the top assembly. A customer concern of incomplete top operations, when the pump continues to run with the control switch held down, may be due to inconsistent sensor readings. For example, during an open top operation, starting from the fully closed position, the front tonneau opens, the header latch unlatches, the trunk lid opens, the top retracts into the trunk and the rear tonneau extends. The next step of the sequence is the front tonneau closing and the header latch latching. If the front tonneau does not close and the pump continues to run with the control switch depressed in the open top direction, the system has failed to recognize the completion of the last step, which was the rear tonneau extending. If the rear tonneau has physically extended and the over-center links have locked in, then the probable cause of the failure is the rear tonneau position sensor reading incorrectly. In these cases DTCs are not set because the sensor is still reading inside a valid range. In this example the rear tonneau position sensor will be reporting MID to the Tech 2. If a customer concern is not repeatable by the technician then the following procedure can be used to diagnose a concern with the top position sensors.
Important: Performing a relearn procedure on the FTC module will reset all of the reference parameters and the top will usually function again but the root cause of the concern will not have been fixed.
Important: Cycling the top system repeatedly will cause the pump motor temperature to rise. If the pump gets too hot the system will suspend operation, send a "TOP MOTOR OVER TEMP" message to the DIC, and possibly set a DTC. The system can usually be cycled three complete opening and closings consecutively without overheating the pump motor. Allow at least 10 minutes after a "TOP MOTOR OVER TEMP" is observed before operating the top again.
The Tech 2 displays four parameters for each panel that uses a potentiometer to establish its position. Here is a definition of each:
<TABLE border=0><TBODY><TR><TD vAlign=top> • </TD><TD vAlign=top>Status: This describes the FTC module's interpretation of the panel position based on the position feedback from the potentiometer. The value from the potentiometer must be outside of the learned reference counts for the status to read open/closed or extended/retracted. When the value falls between the reference counts, the status will read Mid.</TD></TR></TBODY></TABLE>
<TABLE border=0><TBODY><TR><TD vAlign=top> • </TD><TD vAlign=top>Position: This is the live feedback value from the potentiometer for the panel position. The FTC module converts the potentiometer's signal voltage to counts.</TD></TR></TBODY></TABLE>
<TABLE border=0><TBODY><TR><TD vAlign=top> • </TD><TD vAlign=top>Open and Closed Reference: This is a calibrated value that the FTC module establishes after every successful cycle of the top. The FTC module will update this value when the position value goes above or below the last established reference.</TD></TR></TBODY></TABLE>​

</TD></TR></TBODY></TABLE>Table 1 above shows the relationship of the position counts to the reference counts. As the rear tonneau is opening, the position counts are rising. As the rear tonneau is closing the position counts are lowering.
For the rear tonneau position to be considered open the position counts have to be equal to or higher than the open reference count. For the rear tonneau position to be considered closed the position counts have to be equal to or lower than the closed reference count. The front tonneau and top position sensor work the same way.
When the folding top position sensor is reading retracted it is at the low end of the scale and extended is the high end.
  1. <LI type=1>Check the system for DTCs. If any DTCs are stored, correct them first before performing the following procedure. Note that a B3670 (Top Motor Temp Circuit) can be set as a result of repeatedly cycling the top. If this code is stored, clear it and proceed. <LI type=1>If the top will not operate, check the DIC for messages while holding the top control switch down. The ignition must be in ACCESSORY or RUN, and power windows normalized. <LI type=1>Use the Tech 2 to view the FTC module inputs. Capture the following panel REFERENCE counts as indicated. The Tech 2 displays four parameters for each panel that uses a potentiometer to establish it's position. Refer to the definition list above for an explanation of these terms. Use Table 3 below to capture the front tonneau, rear tonneau and folding top open and closed reference counts. The starting values can be captured before the roof is cycled. Cycle the roof either from the closed to open or open to closed position, stopping once the trunk lid has closed to capture the data. Start the engine before beginning to keep the system voltage stable.
    Also observe the front tonneau, rear tonneau, and folding top position counts after each half cycle. If while the top is at rest, any of the position counts change by more than one count it is likely that a concern exists with the potentiometer installation. Readings that change more than one count at rest usually indicate excessive end load on the potentiometer shaft. Remove the potentiometer, and with a small sharp pick, attempt to clean out any foreign material or excess paint from the "D" shaped hole in the receiver and then reinstall it. The relearn procedure may be necessary if the top will not complete a cycle after the potentiometer is reinstalled. Remember to have the top in the fully open or fully closed position before running the relearn procedure. Rerun the reference count recording procedure as described above and once again observe the position counts while the top is at rest.
    Important: If a panel will not reach a given state (stays in Mid) and the top stops moving, that panel's position sensor is likely at fault.
    <LI type=1>Review the REFERENCE counts you captured in table 3 below. Any position sensor that exhibits a variation of three reference counts or more from the start to the final cycle may require replacement. In the table 2 example the rear tonneau closed reference has a change of three counts from the second to third cycle. If the potentiometer readings indicate a variation of three or more reference counts then refer to the "Potentiometer Replace Note" below. <LI type=1>If a new potentiometer was installed then perform the top relearn procedure. After the system is relearned perform step 6. If no sensor was replaced continue to Step 6. <LI type=1>All Model Year vehicles including 2008 that were built prior to October 4, 2007. Reprogram the power folding top module with an updated software calibration. This new service calibration is available on TIS2WEB using the Service Programming System (SPS). As always, make sure your Tech 2® is updated with the latest software version. Important: Cycle the folding top system and verify normal operation.
  2. If the folding top operates normally return the vehicle to the customer. If the folding top does not operate properly return to Step 1. The repeatability of the readings from the potentiometers should be examined very carefully.

Inspect the potentiometer attachment screw to be sure it is tight. A loose potentiometer will exhibit poor repeatability. Also inspect the involved linkage for binding or interference. The rear tonneau potentiometer's harness routing is critical. Refer to the graphics below for the correct routing. If an issue is identified within these areas, correct it first and then fill out Table 3 again to check the variation in the open and closed reference counts.
After the inspection above, the most common reason for a potentiometer to not have repeatable readings is poor fit (clearance) between the potentiometer's white D shaped shaft and the D shaped hole in the linkage it interfaces with. It is an interference fit by design so no play exists between the shaft and the linkage. For this reason it is important to be sure that the hole has no obstructions, such as residual epoxy from a previous repair. Carefully inspect the D hole to be sure the new potentiometer will completely engage the hole. If there is any epoxy present, pick it out with a thin sharp instrument, being careful not to enlarge the hole.
Important: Be sure to install the new potentiometer and wiring harness exactly as originally installed. Misrouting the wiring harness may lead to a wire pinch and/or possible linkage binding. Refer to the illustrations below for the correct wire harness routing. Repeat the folding top diagnostic test after all repairs are done to verify system integrity.
<A href="http://gsi.xw.gm.com/si/showDoc.do?docSyskey=2234169&from=sm#oth10-2234169">Correct Potentiometer Harness Routing




The illustration above shows the CORRECT routing of the rear tonneau position sensor located on the left hand trunk linkage. The protective sleeve (2) on the potentiometer wiring harness is routed underneath the wiring harness to the potentiometer connector. If the sensor currently on the vehicle is not installed exactly as shown in the illustration above, reinstall it as shown and described.

I have the wrench handy in case I need to "tickle" a latch or 2.

I did not get this handy wrench when I got my XLR. I've read about it in the owners manual, but have no idea what it looks like. If it is a socket, what is the size. I have not removed the headliner plug to look at it. To check it out, would I lower the top until it is in the trunk and before the front tonneau cover lowers?

Hey Bruce, thanks for the info as always. Help me decipher what it all means though... Is there something I should make an appointment with my dealer to have fixed/checked? I never got a wrench either... Sounds like I should have one just in case. Is it a typical wrench or do I need to buy a "special" one from somewhere?

I can think of nothing much more embarrassing than to be sitting in a car that has a sticker price of over 100K and the roof is stuck halfway open/closed. With my luck it will happen to me when there are plenty of witnesses and/or the heavens open up and drench my interior while I'm running around trying to find the "wrench" and get it closed. :rolleyes: Thanks!

That wrench should be in the glove box where mine is. They all come with one.
There's a unwritten law that we only put our tops up or down when people are looking at the car. That's when they all get out their wish list and write down type of car it is.
Their very good at fixing the top problems but you might have to have a little patients with this GM thing. Probably lots of back orders.:bash:

Found it right where you said it would be - "in the glove box". Manual said passenger side rear compartment. It is an allen wrench on one side and a phillips head on the other.

Thanks for the info!

Either I'm blind or GM quit putting the wrench in 2009's because I can't find any wrench in my glove box. I'll have another look at my manual and see what it says about it.

The sad part is that if you don't have one, GM has discontinued the wrench. I've been looking for one ever since I got the car. Finally found one through this forum... purchased it from ocool. YEA!!!!

No, I did not look back there very well. I will get her down off the lift today and have a good look around.

Well, I just finished searching for my wrench and no dice. I checked my 09 manual and it refers to a wrench to use when manually lowering or raising the roof, but it does not say the wrench is included. I talked to the parts department at my local dealer and they confirm what someone else said that the wrench was discontinued. I'm waiting for them to call back with the specs of the wrench so I can determine if it's something I can buy at a hardware store or not. Maybe someone here can tell me if the wrench is a special design or just a common allen wrench. Thanks!

It's just an allen wrench on one side and a Torx wrench on the other. Give me a minute and I'll tell you what the sizes are, unless someone else beats me to it...

Here's a picture of mine... T-15 torx on one end, 8mm hex on the other.
