Peugeot 307 mirror heating issue

Hey! I had something similar happen with my 307. The mirror heating went kaput. Have you checked the wiring going into the mirror housing itself? Sometimes those connections can get corroded or loose, especially with the weather changes. That was the issue for me. Where did you see the error stored?

Thanks for the quick reply! I haven't actually taken the mirror apart yet to check the wiring. Good point about the corrosion, though. Where exactly should I be looking for the corroded connections? And I saw the error using an OBD reader from a friend.

Okay, that sounds like the exact same issue I faced. For me, it was the connector where the wires from the mirror heater element plugged into the main wiring harness inside the mirror housing. It's a bit fiddly to get to, but worth a look before shelling out for new mirrors. In the end, I brought it to the workshop. It's hard to say without seeing it, but likely cause is the cable or plug connection of the component defective.

Okay, great! I'll take a look at the connections inside the mirror housing this weekend. If not, I think I'll bring it to the workshop like you suggested. The repair should cost around 95€. Thanks for the help!
