The electric heated wing mirrors on my Fabia Mk1 Comfort are not working at all.

I have just had a new drivers door lock fitted at an independant garage and have had to return twice for related problems since. The windows and remote central locking are working now and I don't really wan't to have to go back again, as every time it goes back they manage to create another problem and it's always made out not to be their fault and another charge is made. Could it be a problem with the small operating switch by the door handle and if so is that easy to remove and check and possibly replace myself?

Although the windows are working properly I have gone through the windows up and down with extended holding switch procedure to reset the convenience module, but it's made no difference.

My left mirror heats all the time, but my right one doesn't. 

 

I'm interested to see any more posts about this topic.

Are you sure it's all connected up properly? Maybe pop the switch out and have a look?

I've popped the switch out and there's nothing there, no wiring at all. It's recently had a new door lock fitted so assume wiring wasn't fed back and connected.

I can feel the back of the door card through the bottom of the hole where the switch fits. Is the feed wire likely to be just loose behind the door card and easily threaded up through the hole and plugged into the switch once the door card is off or does it wind out of reach behind the carrier plate?
