Power Mirrors no longer work on my 2000 F150 4x4 (after sitting for awhile). I sprayed WD40 behind the mirrors and the move manually but not with the switch. Fuse is good so I went to remove the switch itself for inspection?cleaning. There are two buttons on the switch that you can move to unlatch it (looking at it, front and right) but there are also two small nubs (left and back) that also hold it in place. So what do I do, Push in on the two and trying to wiggle it around didn't help and I didn't want to get too forceful in case something else needs to be removed. Any Help?
