Anyone else have a faulty window switch?
Hey guys, I had this issue a month ago where my window switches all stopped working, I fixed it with a simple cycle of the car by turning it off and turning it back on.. it started acting up again today but this time it's totally just stopped working, anyone else having this problem??

Best to take it to the dealership. I'm sure it is just a faulty fuse.

Going to take mine in today as mines just completely stopped now! No lights on the buttons just on that little section and the folding mirrors won’t fold

My m340i was the first production car. Main window switch doesn't work and doesn't light up at night, meanwhile blind spots warning, kick to open tail gate, driver side mirror auto dim aren't working. Took it to the dealership, and they found some of the first production cars driver size mirror causing shortages to the whole car... Dealership still waiting parts to fix my car....

Faulty windows switch G20
This problem is well known on the G20 and its caused by the outer rear view mirrors. The eletronic modul in the outer rear view mirrors shorts as they are not completely water prof. This causes all side windows to stop working as they are connected to the same LIN-bus circuit. It has occurred 3 times for me. First time the workshop changed my right hand mirror, every thing worked perfectly for 2 months and the problem came back. This time it was the LH side mirror that fucked up. Since the is no update on mirror assembly since production start, the electronic modul was changed as this part has been updated. The right hand side fuck up again 2 minutes after the workshop had changed the modul on the left side when testing. So this modul was also changed. So there you go guys, now you know.

Mine has developed the same problem. Some times the switches work but most of the time they dont. I note that the drivers mirror has like a spiders web effect in the glass. Anyone else have this problem with the mirror.

How was this problem fixed. Just started happening to me. About a week later after I replaced mirrors w the carbon fiber caps. Had for 3.5 years now no problems up until I started adding mods
