Anyone know the schematics or can anyone tell me what I need to look for on my O4 QC. My passenger mirror for some reason doesn't defrost. Not sure why, it's not used much. Would still be nice if it worked during snow storms. Any help appreciated.
Thanks

 

I'd check the relay or the switch if it has an separate switch.

 

get yourself a chilton manual. quite possible the element inside the mirror burnt out.
