My passenger side mirror does not operate!
How can one test whether the problem is at the mirror or its control switch?
Is it tied to the door control module? I ask that because nothing else works on the passenger door!

 

Yes it is. Have you checked the fuse for the passenger side door control module? It is on the passenger end of the dashboard, fuse number 15, it is 25 amps.

 

. I appears to be a defective driver's side switch assembly. Left and right mirrors each move in two out of four directions. Took switch apart. And cleaned all the contacts and pad locations . Tested on car, even by jumping across the appropriate circuit board contacts. No luck. Assume I need another switch unless someone else has an idea.
