Which year is your truck? If you are an 02 or earlier, I know for sure that you can open the door and pop the upper triangular trim piece off and check for wires. If the wiring is plugged into the mirrors, all you will need to do is pop the small piece off the driver's door that has the power locks/window controls in it and replace it with the version for power mirrors and buy the switch. The trim piece was about $40. I don't know what the switch costs because we got the one for my dad's truck from a junkyard.If I just get the trim piece with the switch in it, will the mirrors work ?
every thing seems plugged in and the fuse is in place.
