Wing mirrors BMW 3 series - cheshireman
I had a slight accident in the car a few weeks which resulted in the wing mirror glass on the drivers side breaking. Got a replacement from wingmirror man (great service) and fitted it. Both mirrors are continually hot now even though the heater is switched of? Is this a fault with this car or have I missed something? . I have tried changing wire position round but still hot any ideas please

My BMW 3 series wing mirrors are turned on and off by the heated rear window switch. If your heated rear window switch is off, is your rear window on as well as your mirrors?

I may be wrong but I seem to remember that the wing mirrors on my 2004 320d were always on as well. If I was driving down the motorway, rain/mist never settled on the mirror surface regardless of if the rear demister was on or not.

Like I said, I may be wrong but I think BMW have designed it this way.
