Hi everyone -- Just had my driver's door module fail; the window no longer operates, or at best operates intermittently. I tried pulling the fuses in the floor box, no dice. So it looks like it's the module.

Just got a quote from both a dealer and from my indy specialist of approximately $4,000 to replace both modules. They need to now be replaced in pairs due to updated modules having been introduced and the old modules won't function with the newer ones. New modules are $1000/each, plus about six hours of labor plus computer reflashing to accommodate the upgraded units. Needless to say, this is insane. I've had my share of big repair bills, but fixing a power window for $4k is madness.

So my question is, if I source a used module from the same year and replace it, will it function properly or will it need to be coded to the car? I can find these on ebay for $200 all day long. I just want to make sure it's not more complicated than a swap.

 

6 hours of labor? They are correct that new modules need programmed and you need the car configuration changed also. Labor should be half of that.
Buy a module used and make sure it's the correct side as they are D or P and should be marked on the label. Plug it in and learn the window.

Thanks, yeah I noticed that they're D or P so that's easy enough.

Labor did seem high; I had read that it should be three hours for the whole job but the service tech said it's 3 hours per door. Regardless, the whole endeavor seemed way too costly for what it was, saving three hours of labor isn't a dealbreaker either way.

I'm going to order a used unit and have it installed with my interior guy. Should be fine.

 

Great info thank you. I'm dreading this repair. Would you please let us know how it goes with installing the used ones?
TIA

 

Will do. I'm scheduled to have it installed on the 18th of September so I'll report back here how it went.

After this, I'm going to enquire with a few of the big electronics rebuilders like Programa and Remanx and SIA about a refurbishment programme for future reference. There has to be a better option than simply hoping to either find a good used one, or spending several thousand dollars to overhaul the entire system for what should be a simple repair.

 

Thank you Thom_77, I agree makes no sense! Good luck!

 

I'm dealing with the same issue with my Rapide. The problem is almost certainly with a broken wire in the door harness, almost certainly the ground wire.. get an VOM and check continuity from the harness connector to the module connector buried beneath the door card..

 

If it were a wiring issue, would it not affect all the door functions... window, locks, mirror, etc? Only my windows are malfunctioning, all the other door functions work.

I was under the impression that if only one thing died, like the windows, it was likely to be a bad module itself.

 

That is true, if indeed you have a broken ground to the module, it will be dead in terms of the mirrors, but not necessarily the locking.

 

Okay, got my car back this afternoon. Swapped the module, window works. Whole thing cost me $400 for the used module and the labor. Module itself cost $150.

BUT... there's a plot twist.

When they gave me back the original module, it turns out it's an updated unit -- Pektron w/ 2013 date code.

I bought a used module with a 2008 date code, thinking my car had the original modules. I guess a previous owner had the upgrade work done.

Now, I was under the impression that these modules were incompatible with each other, however things all seem to be working. Weird.

So as a precaution, I found an identical part number to what was taken out of my car and ordered it, in case I have another failure due to incompatibility. But still very strange.

 

Thanks for the update. So you were able to swap the unit with a used on and didn't need programing from the dealer?

 

I swapped both my modules from a 2006 Volante to used Ebay Pectron modules and no programming was needed, worked out of the box.

 

Correct, no reprogramming or anything. Just swapped the module with a functional used one and it worked fine.

 

I imagine that, knowing that this logic works (swapping in a used module instead of a brand new one), would be the same for any Module. In my case, I am looking for an updated CRM (convertible roof module) for my 2010 Roadster. The one in it now is the older type and the top moves at a glacial pace, I think due to the older CRM. Does this sound right to you all?
