Mine is doing the same thing. Mine works until the truck is started. Then the window goes down by itself and will go back up but wont go back down again.
I checked everything also. Everything is good. Switch is good(I even replaced it. Swapped relays around and no different. I was wondering if it was the GEM also. Mind boggling.
