Could be in 4x4. Also does it have a limited slip front axle? If it bucks and pops like its in 4wd, could be a problem there. Could also be a problem with one of the drive shafts going out to the wheels. Hope that helps. Oil change in the front diff will tell you a lot more, and relitavily cheap.

Sounds far fetched...but there is a good chance that the speakers are bad. In 2008 and 2009 there were some questionable speakers in some gm cars and trucks. If you have doubts...try replacing just one speaker...even if it is temporarily connecting a known good speaker. You may very well find your solution.

Here is a link to the step by step instructions for the fix. Easy to do. I had the same problem with my 06 H3 and fixed it myself and saved some serious $$$ http://www.hummerforums.com/forum/hummer-h3-17/ac-blower-fix-19208/

sometimes you can pull the release lever and hit the top of the hood and it will come open...and the front grid is more than likely the front grille.

On this website you find fuse box diagram and description for Hummer H3 (2007)

my ;07 fuse panel is under the hood - just in front of the battery - says Hummer on it...

It's the HVAC blower resistor in the air plenum under the glovebox. New resistor and wiring harness is about $70 at the Hummer Dealer.
