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.

Check the battery terminals real good.Make sure they are clean and tight.Check and see if any of the side terminals are leaking. As far as the blower motor.It is more than likely that the blower motor resistor is bad.It is located by the blower motor.Hope this helps.Good luck.

As it's a brand new vehicle, it will be covered under the Manufacturer's Warranty. Call the Garage that you bought the vehicle at and tell them to come and pick it up and have the fault fixed under warranty. PLEASE DO NOT try to fix anything yourself and do not let anyone else other than the Manufacturer's representatives work on the vehicle otherwise the Manufacturer may void the Warranty.

Hi, my research on this issue has turned up phantom causes as sticking valves, ignition switch and seat movement.
On some Hummer, it turns out to be sticky valves in the head. GM replaced the head under warranty and the hummer haven't had any more trouble out of it. There is a recall for the 2006/2007 5 cylinder models and you should be able to have this taken care of at no cost.
Do you have a remote start? The H3 Bypass module has an issue with Remote Start. When this happens to you must wait 10 full minutes before trying to start it again (DONT USE REMOTE, USE THE KEY) the bypass module takes 10 minutes to get out of "theft mode" this is in your manual as well, I forgot what page. The only way to get this to full proof work is to get a shop to "OLD SCHOOL" wire around the bypass module.
