My 08 Hummer H2 wouldn't and it appeared to be battery failure since there was over 70,000 miles on the battery. I replaced it and it then revealed that one side of my air conditioning was blowing cool and the other hot. My display screen went blank and my radio controls wouldn't work. Later the air conditioning problem went away but the next day my car again wouldn't start so I jumped it and once more the air was screwed up and the screen was still blank. What now?

All the classic symptoms of a bad starter. A bad starter will work fine when cold but once it heats up, will require more power to work. Shame on the dealer for not recognizing this! A new battery with a full charge will work for a little while but if its the starter, I'm sure the problem will return Have your charging system checked out (most places will do this free of charge) Assuming the charging system checks out ok, I'd have the starter checked. I hope this solution provided you with the information you were looking for. Best of luck!

I can't solve the problem but was hoping you found the answer. I have a 2003 Hummer H2 and I am having the same problems if started in park or Neutral it will idle fine but if I put it in drive or reverse it will not idle

Did you find the solution and if so could you email me the fix.

u need to change/service the air compressor in ur car.
or it might be the air bags/sensors thats located next to the rear tires.
