I have a 2007 Hummer H3, yesterday the hummer would not shift out of park. The button on the shifter will not press so I can move the shifter to park. After messing with this for a while I took a break and went back out to the hummer and tried to move it out of park and it worked. This morning I woke up and tried it again and it won't work again. Something weird that happened at the same time a's this is that the driverside windows and door lock controls won't work right, all windows will roll down except drivers window and also none of the doors will lock or unlock, can someone please help me.

 

try ctrl/alt/del,,,,oops
try unhook batt and short the leads together. THEY claim this is a reset. there is a control module in the dr door that acts up.
can be other stuff,shift release solenoid,, spend an afternoon reading the forum to learn more
