my 1999 mustang right side mirror does not work. I put a new switch and mirror on the car and no luck. I also replaced the fuse. Does anybody have a clue to what may be wrong ? Thanks Dee Dee

 

Here is the Wiring Diagram & Shop Manual Section for a 99! Hope it Helps!

Thanks KC. I think It may be a ground wire. When I put a jump wire in the harness I can get some of the mirror function to work. I did replace the relay under the hood. Everything else in the car works but that mirror.
