I have a 03 GMC Sierra and the mirror that has temperatures and compass in it worked when I first got the truck. The screen on the right side corner of the mirror is blank. I bought a used mirror off of ebay and I worked fine for a few months. Now I have nothing. I have a friend that is good at fixing electronics boards. He said that everthing looks fine with both mirrors. I just recently changed the ambient air temperature sensor behind the grill and still will not work. Does everyone have any ideas what I can check out to get it to work again. I don't know to get a other used mirror or forget about it. I would like for it to work. Thanks for anybody help.
