Focus electric mirror heating fault

Sounds like a pain! Had a similar issue on my old Mondeo. Could be a dodgy connection. Have you checked the cable or plug going to the mirror? Sometimes they get corroded.

Yeah, I thought about the connections. Where exactly should I be looking? I'm not super familiar with the mirror assembly.

Okay, so given the error code and the fact both aren't working, and I am just guessing, it's probably something before the split to each mirror. Honestly? With electrics, it's often easier just to book it into a workshop. Those gremlins can be a nightmare.

Alright, cheers! Sounds like a plan. Took it to the shop, and you were spot on - defective plug connection. Cost me 95€ to get it sorted. Thanks for the advice!
