Alright I'm new to the Forum and well i just purchased a 2002 Blazer Xtreme and my Overhead display is not showing anything. It does not light up and is blank. I took it down and checked all the plugs and everything is good. Is there a fuse or relay of some sort that i am missing? Or is this thing just strait broken? Also my power mirrors are not working and i'm not sure what else to check. Is there any advice someone can give me to head me in the right direction. Any info is greatly appreciated and I'm looking forward to using this forum.
