I bought my 2012 F-350 used about two months ago and it had a bad drivers side mirror (power fold didnt work). The dealer said they would replace it. Long story short they just ordered the new mirror and were supposed to put it on today. I dont live near the dealer so I just asked to take the mirror so I could put it on myself. I changed it out tonight and the power fold and extend work just fine but now the glass adjustment isnt working right. To switch to adjust the glass in and out is backwards and it doesnt adjust up or down at all now. My guess is that something in the mirror is wired backwards but maybe it could be something else? Any help would be appreciated.
