Anyone know were I could get a manual for an 07 H2? Apparantly I have been told that there is no aftermarket manual for this vehicle. I really need an electrical diagram to try to figure out why I have no power seat heaters or drivers seat movement ability. If someone has one maybe we can pdf a few pages?

Thanx

will try to help you , first did you check your drivers side seat controler it should be under your seat , it will control your heats and seats,
check for power to unit , mike

 

check under the hood for a fuse or relay for the drivers side
control modual the seat heat will not work unless the engine is running .
i can get you a connector diagram but from what i see, is the power comes from the fuse block under the hood to the control modual so if there is no problem with the fuses or relay you might have a bad control modual ,, dealer would have to check that out but the relay could be swaped out with another one in the fuse center just to check it ..

I was looking on eBay and found a few different ones, but didn't buy one yet. Would the wiring diagram be in one of those manuals or are they not worth the money?

 

Helm, got the two book set for my 2003. Not cheap, $135.00...."Contains Factory Authorized Service information written by General Motors"

Link is for the 2007 model year.

Helms is the best out there that I've seen. Only issue is you really need the GM scan tool to do alot of the work.

 

Agree about the scan tool, sure would be handy to have.

 

X2 on Helm and scanner!

quick update. Brought the H2 into the shop and it turns out that pin connector to the controller under the seat had loose pin tension. They say they tightened up the tension and it seems to be working great now. crazy.

 

Have put a duramax into H2 2003,anyone got a wiring diagram for transfer case and the gauges please. Runs and drive's great, but half the gauges don't work HELP
