Having had my fiesta door mirror wiped out by a passing tractor I bought a replacement. Having fitted it it does not "fold on lock". I contacted the supplier who sent me a replacement which still does not, although putting the damaged one back in does. Am I missing something? Does it need reprogramming? I'm at a loss.

hopefully this link will help

Thanks but I've found that article but no joy.

Time to buy a new car hehe

I accept it might be a daft wuestion but... Are you sure the one you bought/received is a power folding mirror. Same wires in the plug?

Where did it come from? 'Tinternet is full of fakes.

In my experience Ford folding mirrors are plug and play.

Yes, its power fold, all works fine apart from the fold on lock business. I've put the damaged one back in and all works ok.

Mirror on the wall did you get the mirror to work at all and if so what was wrong with it
It’s nice to know for the future
