Any idea when they might be available?

Hopefully by end of month.

Hopefully by end of month.

I've reassembled my pump, cylinders, reworked wiring and am looking to test module(s) ASAP. Work has had me traveling quite a bit lately and other stuff going on.

Right now I'm trying to troubleshoot an issue with my top before I try to operate it and damage something. The tonneau is making contact with the hard top when opening the roof and I can't seem to figure it out. Guessing something needs to be adjusted, but when closing the roof everything lines up, so not quite sure what is going on.

Open to suggestions.

Here's a thought, contact any company that works on these units and ask if they have any suggestions. Top Hydraulics is one such company. I believe they rebuild the hydraulic cylinders and it would make sense that they have a good working knowledge of the system. It may be a long shot but worth a try. Good luck

Not sure if that was a reply to me or OP, but in my case pump and cylinders are all from Top Hydraulics. Issue isn't related to either as it does this with all the hydraulics out of the way when manually opening the top. Seems like something needs to be adjusted.

Ironically someone else posted w/ similar issue a couple days ago here.

Talked to Klaus and he hasn't seen this issue first hand.

Seems like top moves freely and when I close it, everything lines up so seems a bit weird that when I open it and stow, it doesn't stow all the way.

I don't see the op hitting anything and there's definitely nothing in the way. Only thought I have is I wonder if the bump stops are adjustable in the back. IF so, might see if I can lower those and if that will accomplish the trick.

Going to go back out to the shop tonight as I'm in the middle of converting the interior from Shale to Black/Ebony and dealing with that as well right now.

I wasn't sure if Top Hydraulics just repaired pieces and parts or if they did the installs as well. If they do they may have seen this problem before.
Good luck on the interior, are you replacing it or dying the old?

I've dyed the carpets already and they came out decent.

Going to paint the plastic trim w/ SEM products and most likely doing that today. If it doesn't turn out very good, then I'll just go and buy the pieces in black; however, the prices people are asking for simple plastic trim on-line is insane so figure I might as well try painting first.

Need a module for a 2004

What is the GM part number for the module? Are all years the same module # ? Warren

 

[mickeytee]

Did you buy a flood car? Looks like you are needing a lot of parts. All modules will interchange but 04-05 need to be updated by a dealer or someone with gm access to upgrade. Thats what most people are selling on ebay old ones. The last ones made are part number 25840734 the old ones run 1200 on ebay newer Number 1400. how do you know you need a module? beware of people claiming they can fix them 90% they cannot 100% they cannot if wet as it corrupts the program chip

I may be a little late to this post but hopefully this helps. Are you sure you need the entire "module"?
My top quit functioning and after diagnosing it turned out to be that little motor that drive the pump. I went to a "you pull it" salvage yard and found the same little motor in a Chrysler Crossfire. I bought and installed that and it worked, meanwhile knowing this was a used motor I found a new one on "ali-express", it took a while to get but have it as a backup. It's an easy and very do-able repair versus replacing the entire pump manifold, typically nothing goes wrong with the manifold, it's the motor or electronics that fail. Hope this helps.

Interesting. How did you bypass the internal thermosister inside the motor that only the xlr has. theres been dozens of folks try and replkace just the motor but without the thermisister hooked up the system wont work . none of the china motors have it.

 

[jts442]

You are correct, the replacement does not have the thermoster, therefore I left it connected, sealed it and set it to the side,, I was a bit worried it would fail not being connected to the motor but everything functions as it should, I do believe it protects the motor from over heating which didn't really make a difference as the original motor failed anyway so is that thermoster even required? It sure beats spending a few grand a dealership would charge (if they could even figure it out) or replacing with a $1,500.00 used module that could fail at any time being used.

 

[jts442]

And as you mentioned, only the xlr has one? Why is that? The same motor is used in the Chrysler Crossfire, BMW's etc. without the thermoster. How required is it? My thought is just a fail safe for overheating ... or having 2 inline fuses for the same light bulb.

 

[mickeytee]

No its way more complex. The xlr being a luxury car the motor also has built in noise reduction that does not feed back thru the radio and the signal from the adaptive cruise that runs thru the amplifier. The thermisitor works two ways. It compares motor temp to outside temp to not allow the pump to run when its too cold for the system. Ive worked and used a variety of pumps to find out all are about 2/3 the power of the factory. So they are going to work harder to do the heavy lifting of thr top. No other car has the weight of the xlr top to lift. So smaller motor heavier top higher load on the system. That can cause higher heat in the wiring and of course the motor wont last as long. The one top hydraulics uses has the proper hp and the thermisistor. Plus the pump can always benefit from a cleaning and rebuild .all for 800. You lucked out as 90% of the time when the motor fails its wet which fries the thermositer and without it the pump wont run.plus in florida you wont deal with trying to open the top at below 32 and burning out the motor, control module and possibly blowing out a cylinder.yoir repair is ok to do if you leave the old motor connected just when the new one gets worn and hot expect melted wires and hopefully only blown fuses. Ivechecked the temp on a used working car and an aftermarket new motor and in normal temp outside the china motor runs 30-35 degrees hoter when new. Thst will rise as it wears. The used is a better motor if not to worn out. I had located a source in switzerland for the proper motor with built in thermoister and ordered 20 right before the tariffs and they stopped exporting. I have run an external hooked to an aftermarket motir and it works but the motors are just not strong enough to last. i expect top hydraulics to go up when he runs out .

 

[jts442]

Interesting and good to know. I do believe the part number for the one I ordered was the same as the oem xlr motor, it just didn't have the thermister built in so I'm at a loss there, but hey, that thermister is small, I just removed from the old motor, I keep it connected and protected and all has been good for a few months now. My top is down 90% of the time here in Florida anyhow, I only put it up when I wash and detail it.
Thanks for the input.

There is no part number for the xlr motor. It was only offered as a complete system. The china ebay motors and the ones on amazon are all the same. They list the same motor for pt cruiser Chryslers vw volvo, several others . they use a similiar mount motor but they are not interchangeable as they claim.. they are not as powerful as the xlr . even the corvette , ssr and camaro pump motors are less hp though they look the same. The extra hp drawing a higher load is why Cadillac said to run the car when operating top. But yours works. Thats a good thing and if in a southern state , used sparingly and no temp exceeded light on the dash it is a fix. But the pumps have never really been an issue. The control module is. Few available and getting pricey
