:lol:Annual fuel cost $715? Hot dog!
I just checked, I have a red, black and white wires loomed together and two blues wires separately. I guess that means I do, thinking that they turn on with the front or rear defrosters.Sorry, I dont know the answer to your question, but Id imagine they would put it next to the power mirrior adjustments. If not there, maybe the HVAC stack, but I', sure you looked all over that.
My standard power mirriors on my 1996 have a single, 3 wire harness coming out of it. If you have the same thing then id imagine you dont have heated mirrors.
