2003 Hummer H2 - Page 6 Questions & Answers
Dash will work sometimes then not. Giving it a smack will sometimes help
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~
H2 battery runs down overnight
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
How do I change my H2 06 Ignition coils and spark
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
It blows cold air out
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.
Sunroof wont open
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.
