Passenger Door Electrical Gremlin

Hi All,

Here's my problem:

The front passenger door lock, power & heated mirror, and window are not working properly. The door lock & mirror do not function at all. The window will work from the passenger door switch but not the drivers control panel.

After cursing the process of removing the door panel with the door lock "double locked" I gained access to the passenger door.

I checked the connectors in the door opening for corrosion and found none. The pins are all accounted for too. I then replaced the passenger door module to no avail.

Yesterday I took it to an Indy for a fresh set of eyes. They claim to have checked all the wires for continuity and found them to be good. They are of the opinion that the General Module (I believe GM3 in my case) is faulty. They say power goes into the GM, but doesn't come out.

Has anyone dealt with this problem specifically? I've read numerous posts regarding door actuators and combinations of these failures, but I've been unable to find a solution this problem. I'm hoping for some feedback prior to the expense of experimenting with a new GM.

Thanks in advance.

Best,

Trent

I'm curious to know what they quoted to replace the module?

I didn't ask for a quote, but the part is $380 new. I'm not concerned about replacing broken parts, but at the same time I don't want to waste money replacing perfectly good parts.

I hear ya Trent. You mentioned in your first post that power is fed into the module, but nothing comes out. How did they test this? Did they do it via a multi-meter or was a specific BMW diagnostic tool? What I'm getting at is, if you can duplicate the result it is possible the diagnosis is valid.

Also, I'm sure you can get a used one from a parts car for much cheaper... much cheaper. Otherwise, you could call a wrecking yard that specializes in bimmers?

Really strange you can try to check with another electrician shop specialized in bmw
So you'll be sure that if they said same reason then change it if they said diffrent find 3rd electrician and tell us what they said and how they checked and we can decide with you where to go

But did you go to any service cleaning shop they sprayed detergent or cleaning agent or water to clean buttons ??
Also you can open the driver side buttons and dry it and spray it with electronic cleaner god knows it may work again
