My van has the short arm, power heated mirrors, with signals. The mirrors themselves have the heat/defrost icon on them. However, I can't find the switch to turn them on. I also have the rear defrost, because my van has rear privacy glass. The rear defrost switch/button is behind the steering wheel on the right side of the gauge cluster, and the space above it is a blank. Did they forget the switch? Or do the mirrors defrost with the rear windows? The mirror heat icons do not illuminate when the rear defrost button is depressed, I don't know if they're supposed to.
A little help from heated mirror dudes and dudettes?
