Hummer not available or wanted in TN

I think it may be coincidence and you have a fuel pump that has failed. Have the fuel pressure tested and replace the pump and filter as is necessary.

I was a Technician for Hummer for over five years and replaced a large amount of these gauge pods for multiple different reasons. Sometimes a simple updated reprogramming was needed, but most of the time was just installing a new unit all together. There are places that will repair these units but the price is usually close to a new unit.I hope this info helps!~subyguru~

sounds like a short circuit, check any aftermarket items first, a slow but easy way is pull on fuse at a time and check current flow from battery un til it stops, when it stops check fuse and see which system is draining

Sounds like there is a crack in the vent that leads to the drivers side, and hot air from the engine is leaking through.

when you open the hood on your H2 the is a cover over the top of the motor. to remove it you have to remove the oil filler cap and pull out the dip stick. when those are removed you should be able to remove the cover by pulling up on the front edge. after that is out of the way the ignition coils are right on top of the spark plugs and are usually held in with 2 bolts per each coil pack. unbolt the coil pack and pull on the coil and it should pull out of the hole( may be stubborn) them find out what size the plugs are and the plugs are in the bottom of the hole

nearest you will get ,so i would imagine that it will if it doesnt then make it fit

Hello,
An all too common problem is the heat/air blend door in the climate control duct system. The blend door is either stuck, or you could have a bad actuator, ( the actuator is the device that moves the blend door based on your setting.)

I would likely have that checked first.

I hope this helps you.

The motor has two wires. just jump 12 volts to them.

I'm not sure what's going on with your circuit, I have also a same problem. when I replaced the switch the sunroof worked. I ended up taking the old switch apart and when i poped off the cover some of the plastics inside were broken and wedged in places they shouldn't have been probably causing a short. I am not real sure because when I opened the switch it pretty much fell apart. Liquid Roof Coatings Application and Uses BuyLiquidRoof

Probably too late for you, but I just "fixed" the stuck sunroof. I didn't want to spend anything and didn't care if it worked, I only wanted it closed. By taking the motor off, I was able to easily push the sunroof closed, then secured the motor back in place and it keeps the sunroof locked, closed. I tested the seal by running water over it, and all is good. Liquid Roof Coatings Application and Uses BuyLiquidRoof
