Hi all..

I am experiencing a problem with my car. Right front side is dead. El-mirror not working, el-window or el-locking on the FRONT right side.

The rear right side is working just fine.

Any suggestions what it can be?? or Where to look???

Thanks..

Bad/faulty wire. Start from the switches and follow the wires back to the fuse box

I was thinking something like entire power wire/cicuit/fuse is faulthy to this door. Any fuses I should check? anyone know? Anything else than following each wire from switch to fusebox?

thanks!

Inside the door is a control module. It has a microprocessor that listens to the controller area network via a serial bus. This CANbus scans the switches for the mirror, window, and lock and communicates the desired motion to the door module.

Inside the door module are solid state drivers and relays to provide power to the devices. None of the moving devices is connected directly to the switches.

12 volts goes to the door module when the key is turned on. This also wakes up the controller. If you push a mirror switch the SAM listens, and whispers to the door module to move the mirror.

Check fuse number 2 (30 AMP green) on the rear SAM assembly. It is in the trunk, left side by the tire tools. Check fuses 21 and 22 (30 amp green) on the interior fuse block, behind a cover on the left end of the dash. Open the door to see it.

Could be a broken wire to the passenger door. Could be a nackered door module, or just a loose or electrically dirty connection on the door module.
