Hello, I just got an 08 Hummer and I love it but I am having one problem I hope someone can help with. I have a "park-tilt mirrors" function that, according to the manual, you set to cause the sideview mirrors to tilt down when you reverse. When I turn the function on using the DIC, it does work but the mirrors go almost straight down. So I look in the manual and it says to set them, you place the vehicle in reverse, set the mirrors, then take it out of reverse and it saves the location you have put them in. However, when I do this the mirrors stay in place pointing where I had them when in reverse (they do not move back up). Then when I put it in reverse again, they point even more at the ground. I do not understand what I am doing wrong (if anything)? Take it back to the dealer? They are kinda dumb...if you ask me. Any help from the pros?
