F80 M3 Power Window Issue

f80mthirty · 03-17-2022, 08:40 AM

Hello,

I have been struggling with my ghost f80 m3 driver side front window. All of my windows besides the driver window goes down. I tried to change the regulator/motor and no solution. I checked all three fuse boxes, the one under hood, FEM module and trunk fuse box with no luck. I also tested the switch which is good. I’m having no luck with this and it’s driving me crazy. I’m attaching the codes that the car is throwing.

I checked the FEM with the fuse checker and they all lit up. Also, all the other controls that the FEM controls work perfectly fine. Only one driver window doesnt go down.

The fault code description says something about input voltage. The FEM contains fuses/relays that are not serviceable, so u have to replace the FEM. If you get a wiring diagram you can check output voltage from relay and go from there..

Did you ever get this fixed? I am having the same issue right now with my car.
