Battery dead, won't start. Jump started and installed new battery. Air conditioning had hot air coming out of driver's side, cold air out of passenger side. Display screen went dark and radio didn't work. Air conditioning reset and started working properly but radio and display screen still do not function. What can I do to reset all elements?

Hummer H2 engine won't turn over, key won't
Dead Battery? Bad starter motor?

Try pushing on the brake and making sure its all the way in park.

Turn the steering wheel back an forth a little to remove the key.

None of those work, Call triple A, find a shop.

Transferbox problems
It's actually stuck on the 4xL, if you keep driving it it might coz a big damage to ur 4wd gear box.
you should change the transferbox (it cost here in Dubai around 1350 US$ with labor charges).
