From another post but thought I would separate. Wing mirrors not moving/working. Bought a switch off eBay. Installed and it gave power and wing mirrors move however

Put switch in passenger location and it moves the drivers mirror.
Put mirror in neutral/off and moves both mirrors
put in drivers side moves passenger up and down

all movements are erratic. It moves but I can't set the passenger mirror left and right just up and down. I can adjust the drivers but it seems to move the mirrors both at the same time so....

is is the switch bad? If so I will send it back
has the switch been crossed wired after a repair causing it to act erratic?
is it the wiring?

it is weird. I assumed I would put it in and Bing it would work correctly. It's 50% working which is 50% better than before I guess.

Any thoughts??
