SOURCE: 2009 Hummer h3 won't start

My H3 didn't start this morning. I noticed something unusual about my truck when I first tried. The alarm had a weak sound when it went off. The fact that it turned over but didn't start made me believe it was not the battery. I was trying to call the mechanic and a wrecker to get my H3 fixed. However, before that I got the wrecker out there, I went to Autozone. He told me it sounded like the battery and cold weather kills the battery. So 3 hours have passed and temperatures warmed up to a cool 56 degrees. I was going to put jumper cables but out of curiousity, I said well let me crank it and see if it was cold weather. Sure enough, it cranked right up.

Either way, I am going to take it to Autozone and have the battery checked. I can't miss another day of work due to an old battery.

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.

Check the relays in the fuse box. It appears that the solenoids for locking the doors are working correctly. However it appears that the lock solenoid is not working properly.

H3 battery dead and doors are locked


Try charging the battery a bit by snaking the positive jumper cable underneath to the starter post where the big cable connects, and the negative jumper cable to a good ground on the frame.

When, a key lock sing blinks on the dash of hummer H3, and will not start, what can i do ?


make sure all windows are closed
get out of the Hummer, using the central lock, lock the 4 doors
close the door
then open it with the KEY
then try to Start the Hummer.
(repeat several times till it works)
I am facing this problem now and that is the only soluttion I found. Untill i buy a new remote key that got stolen :S

In order not to fall in this problem, avoid opening the hummer with the key and directly locking the four doors using the central lock before starting it.
