Interesting. The thermostat impacting the mirror heating circuit? Could you elaborate on the diagnostic process you followed to identify the thermostat as the root cause? I'm curious about the diagnostic steps.

Well, I'm no expert. My mechanic tracked it down, I just know he mentioned something about the thermostat sending weird signals that messed with other circuits. Honestly, I'd get a workshop to check the Volvo too, could save you headaches.

Appreciate the insight! I followed your suggestion and took it to a trusted shop. As suspected, a corroded connector was the culprit. Repair cost was 95€. Thanks again for the help!

Hey there! I had a similar problem with my Opel Astra, but it wasn't the cable. After a bit of fiddling, it turned out to be a dodgy thermostat. Did you check that? It might not be the exact same, but the temperature control circuits can be weird.
