Does anybody have access to the mirror wiring schematic?
I originally thought I had a bad mirror motor, then possibly a bad switch on the drivers door. Testing has proven that both the mirror motors and the switch are functional.
It SHOULD be easy to trace the problem, but... the wire colors in the passenger mirror housing and the colors on the back of the control in the drivers door don't match!
First off, I purchased the car used from a dealer, but the history shows only one owner previous. That being said it's possible something happened along the way and one of the doors could have been replaced. I know at a minimum i have at least two connectors to trace through, one at each door hinge. I'm betting there is something in between it goes through since the wire colors change.
BTW, I found a diagram for an older model, but it had three wires at each mirror. I have four, two for up / down and two for left / right.
