Come on. The compressor sounds like it kicks on under the hood but nothing else happens.

It doesn't seem to be over heated. The coolant is fine. Whay could this be?

was hit from behind and it caused $10,000 damage to my H3. Body Shop fixed it but now gas gauge is not reading correctly. They took it to a dealer to put on analyzer to see if date of accident show up. no date at all showed. They did not put in a new fuel pump due to date not showing. Was fine before accident. Am I stuck to put in a new fuel pump?

Not turn on. They turn on and off when they want. Have it for a month and this just started happening 2 days ago.

Ran out on highway put gas in drive it 50 miles parked overnight now won't start fuel pump is new fuel filter is new ???

I want to leave an aux cord plugged in. The light won't go off. Will it drain the battery if I leave it plugged in? I read that usually one of the lighters will turn off when car is turned off. Is this true in the H3?

Sounds like it is coming from the front of the motor

I had the thermostat replaced. The heater core was checked & the aculators .

I have 246k miles, and had a transmission rebuild @ 220. When driving hwy speeds for 15-20 min, I will loose overdrive and my Rpm will jump up. When it happens it is smooth, and only recognized by the increase in rpms. This of course causes the engine temp to rise. I have no other gear issues, and they all make smooth transitions.

H3 Hummer wouldn't drive in regular drive, only 4 wheel drive. The mechanic said the transfer box was damaged internally and found the radiator was cracked after smelling fluid. Said it was probably from accident, but can't say for certain. Car was fine before accident. Landed in ditch at a 45 degree angle. My daughter had trouble getting out of the car until help arrived. Had to be towed out. Comments?

after resetting key pass code issue car started. no turn signals, neighbor checked fuse box with a tester after which car will not start. when you turn key no display or chimes but radio and head lights work, no horn and when you use the key fob to lock car lights dont flash

Drove 1 day then hummer overheated , returned to dealer replaced radiator, radiator cap, water pump replaced, thermostat replaced, checked over at GM dealership, Now the same thing happened again, any advice??? Why is the same thing happening?? Hummer overheated after 20 miles in outside temp 76 degrees. Only drove 3 days since work was completed.

During the Christmas hustle & bustle when unloading gifts etc, while having my hands full, & catching a neighbors toddler from running into the street-- I SLAMMED THE REAR-END/ LIFTGATE DOOR CLOSED. (Fortunately I stopped the toddler, but dropped the gifts lol) The license plate pocket popped out & the handle is still intact but not pulling to open the door. PLEASE HELP

Shouldn't this be a recall on GMS part as a safety issue? I have been told that a cracked manifold is a known issue with these 5 cylinder engines. Can it be welded? Would that be as expensive as a new replacement?

It squeeks/rattles when I drive,,,sometimes at an idle a little bit...but stops when I brake. It sounds like its coming from the front passenger side of the vehicle. But it seems to be getting louder. Then for stretches going down the road the noise just goes away. Make any sense to anyone?
