Hi all I bought a 300 a couple weeks ago and I’m slowly crossing off all the things wrong with it and one of those things were the mirrors not being hooked up upon inspecting the drivers side mirror I found that it was a mirror with heating so I cut away the little strip of plastic blocking the original 1991 clip from going into the mirrors wiring and got it connected but the mirror will only fold in but won’t adjust. Anyone know what it could be?
