Hello Guys.

I own 2001 X5 4.4i and I recently replaced a front-passenger outside door handle carrier. I had experienced the job before, so I got it done pretty well, only took about 30 min. But there was something carzy happend after that which I still can't understand.

1. The passenger side door lock, window and mirror doesn't work from the dirver's master switch. (the other 3 doors are perfectly fine)

2. The passenger side door lock doesn't work from the remote key.
(the other 3 doors are perfectly fine as well)

3. The passenger winow is still working only from the passenger switch.


I have checked fuses and wires but no blown fuse or disconnected wire, they were just looked fine. Is this some kind of module problem?
Any ideas? Please help guys!!!
