Electric Mirror Quandry

[Simunro]

Hi folks, 

I have just purchased a wee run about mk6 1.4 fiesta zetec climate and it's so far a great car. Only have 2 issues, first is boot only opening with the key (now resolved with a replacement solenoid from local scrap yard).

The second (and still have this) is the drivers mirror doesn't do anything when using the selector. The passenger one is fine. Have checked fuse, (driver mirror plugged into passenger works fine so not mirror motor), tried a new switch but still same issue....what else could it be? Any help gratefully received.

Thanks

Have you checked the wires before they go into the door and then at the mirror plug, there is a chance the wires could be broken inside the the rubber wire tunnel between the car and the door due to fatigue (as the driver's door tends to be open and shut more than other doors)
