I think you'll find that the top WILL malfunction again... once the top starts not operating correctly, they usually continue to not operate intermittantly. At some time, it will just not work. The trick is to get it to the tech when it decides not to work. And you're correct... these babies are CUCKOO. But what a CUCKOO car to have, huh???

I've been away for a while and now am back. I missed the Crew, but I have a selfish mission.

As described in this thread, my trunk lid started to not open last fall while on vacation. The top would go up and down as normal, but the trunk "lift" switch wouldn't work. I took it to a not-too-local Cadillac Dealership and was tickled to death because they only had to re-flash the Body Control Module. I thought that was the last..

Again in December, while at home, the trunk again malfunctioned. i advised the Service Dept at my local Cadillac dealership about my history and they re-flashed the BCM and it started working normally. The Tech stated that he would "not recommend replacement" of the BCM at this time.

Over the weekend, a similar problem occurred. This time the trunk will open with the keyfob and trunk lid button, but the "close" button doesn't respond.

I was very disappointed today to hear the Service Manager report that the Technician reflashed the BCM and that all systems are now fully functional. That's not the concern, but rather the Tech wants to "replace the trunk closing switch" to see if that'll fix the problem. Think about it. The switch didn't work before re-flash; it works now; and he wants to replace it to "maybe" fix the problem.

After I calmed down a little, I calmly asked the Service Manager to request of the Tech his logic and how he came to that conclusion. WTF is he thinking!!!! Common sense would point to something other than a momentary contact switch that didn't work before re-flash and now works.

If anyone with this problem ever did get a solution to the problem, please let me know. I don't want to get my XLR back and it need a re-flash in two months from now, somewhere I can't get to a Dealership.

Mine turned out to be 2 of the sensors ....

XLR KEN · 02-09-2012, 06:43 PM

Did they happen to re-flash the BCM when they replaced the 2 sensors? My concern is that your two new sensors were just window dressing.

I'm wondering if the Top Control Module in the trunk is somehow linked in to the trunk (open/close) functions. I don't want to go and have a new BCM installed and the root problem be another module that may simply have an intermittant problem. Due to the trunk function being such an related part of the top operation, it may be a source of the problem. I just don't see how a re-flash of the BCM would reset the Top Control Module. Also, the top as always worked when the trunk was malfunctioning.

I'm going to have them look at the Top Control Module tomorrow to see if it has any evidence of water infiltration. Looking back, it does seem the problem comes up after either driving in heavy rain or going through a carwash. It's sad when I have to troubleshoot my XLR for the "certified Tech."

Mine done the same thing it would open but wouldnt shut, turned out I have to pull the little latch that holds the trunk back into place then the button on the trunk will close it (may need some WD 40 to make it slide back in place) that fixed mine.

Excellent TOP DOG. I'll try it in the morning. The horror of my Cadillac Service Center went to an all time high this evening.

Last night, I stopped by to personally check on any resolution to the problem on the way home from work. The Service Rep advised me that the Tech had ordered a new "close" switch and it would be in the shop this morning. This was contrary of what I told them to both check and/or do, but I was given bad info that resulted in me making bad assumptions.

The Service Rep recanted on his previous story and said the Tech actually had only "cleared codes" and not re-flashed, and the failure codes had come back with "Bad Switch." I took it with a grain of salt and waited.

It didn't take long. By mid-day today, after the new switch had been installed, the system "malfunctioned." They were still working on it until closing.

Now the HORROR. While passing the Dealership this evening on the way home at 06:30pm (Service Center closed at 02:00), my wife noticed my XLR in the side lot with lights on. We circled around to go back and check and found our XLR in the side lot with the engine running, lights on and doors locked. I found the Sales Manager in his office (almost everyone else had gone home) and advised him of the finding, and with his help, I found my keys in the Service Center laying out in the open on the counter.

You can understand why my XLR is now back in my garage and I'm looking for another Dealership to work on it. We left with our XLR immediately. I'm glad to get the XLR back no matter the current condition. I will be having a few meetings with the Management of the Dealership when they come back to work on Monday.

Wow! I'm sorry to hear that story, Ken. I'm glad to hear you were able to get SOMEONE at the dealership to get your fob back.

b pappy,

Today I opened up the compartment housing the pump and Top Down Controller and found my drain tube had two broken off tabs in it. I fished them out and blew out the drain line.

The good news is that the compartment was bone-dry. There were no signs of water infiltration. Even the little flapper valve on the bottom was in pretty good shape.

Thanks for the heads-up thought. IF I ever have water get in, I now know it will drain properly.

On a side note, the XLR is operating properly by all exercising I've done with it today; trunk up/down & top up/down. I did notice the "TECH" (and I use that term loosely) left the emergency key access cover off when they left it running in the parking lot last night; I'm grateful it's theathered. I just stuck it back on and all is well for now.

All this discussion about water in the trunkwell convinced me that I should go ahead and check mine, even though my XLR has only ever been in the rain one time.

This first picture shows some interesting markings that were revealed when the trunk mat was pulled up to gain access to the trunkwell.

The second photo is a good shot of the left trunkwell with the cover removed.

The trunkwell was dry as a bone, and an inspection of the drain showed that the drain tube was clear and open. My tube has the "duckbill" style of drain tube.

Thanks for the heads-up. Even though mine was clear and there was no water in the well, it was a few minutes well spent, for peace of mind.

It seems like it would be a good idea to check it after any time that your car has been exposed to water.
