My e90 07 Pax side mirror stopped working getting a 9cc4 error, and (communication with mirror was disturbed)D904, I checked all the wires and even swapped mirrors, this same mirror will work on drivers driver-side plug; so I know it works, This started about 6 months ago, when I approached my car the mirror was folded outward and wouldn't align. I left it alone

Driver side works and folds
Check fuses, they are both fine
Swapped mirrors nothing will work on the pax side
Check 12 v power is going to mirror wire through the door panel
Swapped Master switch
Took the door apart looking for frayed wires nothing..

In Inpa when I hit the window switch to the right ( for the pax side ) both indicators turn on for both sides, instead of the passenger side only


How does Kcan stop the function of the mirror,? I searched forums and still can't figure this out. Is there a shirt circuit reset for this or anything?

Any help would be appreciated!
