CT200h Mirror Heating Issue
Summary of the thread
A 2020 Lexus CT200h is experiencing an issue where the mirror heating isn't functioning, leaving both side mirrors icy. The fuses have been checked and are fine, but an error memory indicates a fault in the mirror heating circuit. Possible causes include a faulty heater element, a break in the wiring, or a shared connection issue. It is suggested to have a workshop inspect the cable and plug connections to resolve the problem.

Thanks for the quick response! The error code doesn't specify a particular mirror, it just says something generic about "mirror heating circuit malfunction". Could it really be a broken wire? It seems odd that both would go at the same time.

It is unusual for both to fail simultaneously, but a shared connection or a common wiring loom could be the culprit. I'd advise you to have a workshop check the cable and plug connections. In my case, I also went to the shop in the end and they fixed the electrical fault.

Okay, thanks for the advice. I'll book it in with a local garage. The mechanic suspects a defective cable or plug connection, and the repair should cost around 95€. Hopefully, that fixes it!

I had a similar problem with my 2018 Opel Insignia. The symptoms sound identical! My mechanic suspected a faulty heater element in the mirror itself, or a break in the wiring. Did the error code specify which mirror, or is it a general fault?
