If your car is pre 2001 then the heated mirrors are on all the time. You'll be able to tell as the rear window heater switch only has a picture of the rear window on it, whereas later cars have the rear window and door mirror on it as it controlled both.

Yes, the rear window heater switch only has a picture of the rear window on it.

It's a useless waste of energy :crying:

Do you think that if I change the heather switch then it will work like post-2001?

Didn't know about that either, and yes it does appear to be a waste of energy considering how hot they get... <_<

Carles, have a look at the following thread, it may not be possible to change the heater switch easily:

Yeah it's really silly that it's on all the time, no idea how they thought that was a good idea!

I'm not sure if it's a case of just swapping the switch, as I have no idea if the wiring is different. However I can't imagine it being that hard to fit a switch somewhere or even somehow wire it into the existing window switch if you're good with electrics.

Thank you very much for your answers.

Maybe find the fuse or relay and disconnect is a temporary solution until the next winter.

I'll try and I'll let you know.
