SOURCE: how do i shut off my change oil light in my h3

I'm not 100% on this but I think it's like a lot of GM's; turn the key to the "on" position(not running), stomp the gas pedal to the floor 3 times within 5 seconds & the light should flash & go out.

SOURCE: I have a 2007 H3 hummer, suddenly my fan does

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.

SOURCE: the blower motor stops working sometimes

I had the same problem and sloved it with the help of google images, hummer blower motor resistor. Under the glove box the blower motor resistor can be found. It comes loose and the blower will work at times. When I reached under and pushed the connector in, it works fine. It was fixed within minutes. I am a gal with a Hummer and save myself a huge dealer bill. Good Luck!

Locating the voltage regulator located on 2007 Hummer H3?


I don't have a shop manual for a Hummer.
But GM trucks built in 2007 use something other than the alternator to control voltage. Sometimes its called a generator control module and sometimes it is inside the body computer or the ECM.
You may need to check with someone who specializes in Hummers for the answer.
