I have a 09 silverado 1500 WT
It has heated rear window but no heated mirrors. And I can't see a wire for heated mirrors in the door compartment (although I haven't opened the door panels in a few months) I do seem to have 2 wires (it feels like 2) going through the door boot (I haven't opened the boot to see the colors but I assume it is for the door open sensor, but I could be wrong)
I am wanting to add tow mirrors to the truck and especially heated mirrors ( I plow with the truck and really would love the heated mirrors) I was wondering how I would go about adding heated mirrors ( like I said I have the heated back glass so shouldn't the wiring for heated mirrors already be in the truck as I think they run off the same switch and I'm gonna assume the same harness ( I could be completely wrong and they could be different harnesses)
Looking for help as I am wanting to do this conversion if possible
