SOURCE: 2006 H3 Hummer AC/Heater Fan Motor

I brought my 2006 H3 in to the dealer for the same thing. My blower stopped working all together but it started as an intermittent problem. He said he had to replaced a diode or resistor either behind the switch on the dash that controls the fan or on the fan motor itself. Have not had a problem since but that was only about 4 months ago.

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.

2006 h3 will not lock or unlock doors with shifter

The settings for these can be reprogrammed. Look up the reprogramming sequence for that particular vehicle. I assume it has just been programmed not to lock or unlock from park.

My key fob stopped working for my 2007 hummer h3 i changed batery n nothing please help

Climb into the vehicle and close the door. Insert the key into the ignition but do not turn on the vehicle.
Hold down the "Unlock" button on the driver's door while turning the key to the right to the "Accessories" position. Continue holding down the "Unlock" button.
Turn the ignition key back to the "Off" position while continuing to hold the "Unlock" button then return the key to the "On" position again. Then return the ignition key to the "Off" position. As you complete this sequence, the doors will lock, and the horn will sound, indicating that you've entered the programming mode. At this point, release the "Unlock" button on the driver's door.
Push both the "Lock" and "Unlock" buttons on the key-less remote and hold them for roughly 15 seconds. Release the buttons when the locks click again.
Insert the key into the ignition and turn it to the "On" position. The horn will honk once more. This indicates the programming has been successful.
Remove the key from the ignition. Climb out of the vehicle and try locking and unlocking the doors with your remote key.
Tip

The H3 uses a Tech ll code system that often cannot be re-programmed without the help of your local dealer. If you are unable to reset your key-less fob using the steps above, your local GM dealer will be able to help.

Starter not working with remote

The remote start isn't compatible with your hummer. The factory security system isn't able to allow a remote starter to work with it , just the way it was designed for security. You can bypass it with a adaptor but you would have to disable your security system. Most professionals won't do that, you can fin a back yard machanic to assist you. But then it affects your insurance rates now that your security system is no longer working. If you can spend the big bucks some professionals can get the viper brand of remote start to work on hummers. I've experienced this with a 07 H3 tried an inexpensive aftermarket starter it worked twice on the 3rd time it would then make my hummer go into anti-theft mode and wouldn't start engine for 10 min, the lights would work on inside it would turn over when I turned the key but it wouldn't start. I took it back to the company that installed it they woul reset it and it woul happen all over again. So I then went to a different company explained situation they again reprogrammed it and told me the last people were setting it with the driver door open so it wasn't going to start without the door open. This time the remote start only worked once then the 2nd try would go into anti-theft mode making me wait 10 min before it would start the engine. I couldn't spend the $ to try a viper brand an they charge you to uninstall them so I have since sold it and just kept the key fobs so the next owners wouldn't have the same trouble. The second company did suggest trying a relay system to see if that would solve the issue but I didn't get a chance to try it, so maybe mention trying the relay system with your currant starter before paying for a expensive system.

May be keyfob needs reprogramming.

Keyfob remote reprogramming is not very difficult but on some cases it can be done by dealer service tools.

If the remote s faulty then key fob will not get programmed.

Insert the key in ignition. Turn the key to on position, and cycle the key three times off-on-off-on-off-on. Then with the key fob remote select your remote and then try to operate the vehicle with remote.

These are just the basic procedure, but sometimes it will not help.

On that case dealer is the only option.
