Not sure when GM started with heated mirrors and I think my '02 Furd was the first pickup I bought with them. They didn't work on the blind spots either. And because they're below, thawed water runs down and freezes on them just like the GM.
RAMs don't have heated blind spots either, but at least I can fold them down on the 2500's and not have ice on the blind spots. Dumbest thing is the timer for the RAM isn't even close to long enough to melt snow during heavy snow. Constantly pushing the button to turn them back on. Udderly asinine.
