Clio Mirror Heating Fault

Interesting. I had a similar issue with my Clio, and it drove me nuts. It's like trying to see through a frosted window when the mirrors are iced over. I never got an error code, though. Did you check the voltage at the mirror connectors themselves? If there's no voltage, the problem is upstream, probably somewhere in the wiring harness or a relay. If there is voltage, then the heating elements in both mirrors have failed simultaneously, which is unlikely but still possible.

Good shout on checking the voltage at the mirrors directly! I hadn't thought about that, been too focused on the error code. Any idea where the relay for the mirror heaters is located on the Clio? A wiring diagram would be gold.

Unfortunately, I can't pinpoint the exact relay location on your 2002 model; they do move things around from year to year. If I were you, I would visit a reputable workshop. Given the error code and the symptoms, a mechanic will quickly find the cause of the electrical fault. I really think the cost won't be too high.

Thanks for your input. I took your advice and booked it in. Turns out it was indeed a corroded connector in the door wiring, just like you suspected. Repair cost was 95€. So glad it's sorted, much safer now. Thanks again!
