2007 Hummer H2 SUT - Answered Questions & Fixed issues

The VIN number is behind the windscreen on the lower left corner. Some also have it inside the glove box. American and Mexican made Hummers do not have a chassis number as such.

most blinkers uses relays, and when they flashes fast one light is out, but you replaced your burnt bulb might be a bad relay.

either the key is ruined or you need new ignition , have you a spare key ?

its probably the chip in the key is wore it may need to be reprogrammed

Replave the lock with a matching unit badsed o n the key type number

Sounds like either a broken motor/transmission support (most likely) or a defective universal joint in the drive shaft. If you need further help, reach me via phone at https://www.6ya.com/expert/tom_1788908372a4836f

check battery condition with a load test first. Make sure terminals a bright clean and tight

As with most GM cars and trucks, you turn the key switch on but don't start the engine. Depress the gas pedal to the floor 3 times. The change oil light should flash. Turn the key off, then start the engine.Check your owners manual for details.

Ray, this appears to be with the power steering system. I would start with verifying the condition and power/pressure output of the power steering pump. You did not state the mileage or vehicle maintenance status, however even well maintained vehicles and components do fail at times.

The Powertrain Control Module (PCM) is shutting down your throttle body control for some reason and limiting how much throttle you can apply. The only way to find out why it is doing this is to scan the PCM for Diagnostic Test Codes (DTCs) and diagnose any existing codes accordingly. It is very likely to be caused by a fault in your throttle position sensor or accelerator pedal position sensor circuits.

There is a Technical Service Bulletin (TSB) for your vehicle which covers a known problem with reduced engine power and sets DTC P2138. The known problem is that the Accelerator Pedal Position (APP) sensor circuits are being infiltrated by water intrusion into a connector and causing erratic voltage readings at the PCM. It is TSB reference # 07-06-04-019D

what type of error

Please see my tip at http://www.fixya.com/cars/r5932051-check_engine_light_check. These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

when the engine is cold the oil pressure should read 60 psi
when the engine warms up at operating temp. it should read 12-16 psi while running at speeds 40+ it should read about 38-42 psi.
it it reads all that its not you sending unit
remember its a GM they use the poorest oil pumps on the market. usually I won't see a pump going out untill over 100K or so. its the same frame as the suberben, yukon, tahoe,denali.
4WD will make the job 3 times harder. If you do have the job done ask for a high volume pump

first i would check the oil level make sure it is ok if it is fine the its the oil pump failed but that should be too new to fail but never know

where is the hummer h3 horn located as i want to change it to a smaller airhorn? thx

Check the left side CV axle.

I have the same vehicle and was able to remove mine with the following steps: 1) remove light behind each rear of luggage rack rail using phillips screwdriver (one screw each side). 2) remove molding underneath each light using T20 torx driver (2 screws each side). 3) Loosen cross rails nobs. 4) Side cross rails off of roof.

Check your coil packs and wire's.

maybe a servce light had a simular problem on my v8 ss and all it was was time for a service

Hold the brake and shift the gears into drive then back into park it should help .... are you sure you dint bent the key .
