The radio is in theft lock due to being disconnected from power, you (or the original owner) where given the code and instructions on entering it with the owners manual and other new vehicle paperwork. If you do not have this info contact any GM dealer for assistance with obtaining your unique radio security code.

SOURCE: 2006 Hummer H3 fails to start periodically

If you look in the owner's manual it will explain this. Happened to me a bunch of times, really embarassing. It is an additional anti-theft device . If the computer senses that the key is inserted improperly, or that it is not a perfect match for the code it has in its memory for your key, it shuts of the gas supply to your engine for approx. 10 minutes to defer theft. Still happens to me intermittently. Now only very rarely. Total pain. I cleaned my key..carefully, with WD40 and after drying put just a touch of graphite on the key and started the beast a number of times. My dealer didn't read the manual either. You must wait the full ten minutes before trying to restart....otherwise it never totally resets and (the first time this happened to me) you can sit there and fight it forever.

I don't have my owner'smanual handy to refer you directly to the proper pages, but its in there under theft deterent. Hope this helps......and that Hummer can provide aneasy fix for this.

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.

SOURCE: how do i reset oil change ligth on 2006 hummer h3

To reset your maintenance reminder system (even if the light hasn’t come on yet), you’ll need to turn your key to on (but don’t start!) and make sure your odometer is on TRIP A. Then key off. Press and hold the Odometer/Trip button. While holding down on the button, key the ignition to on (Don’t start the engine!) The display panel will count down from “------“ to “-“Continue pressing the button until the Trip A is displayed. After this step, you are done.

SOURCE: 2006 Hummer H3 a/c & heater fan/blower failed

Probably too late now, I am sure you have already fixed it, but mine did this and it was an electrical part that is mounted right beside the blower fan. The part was OK, but the plug into the part was arcing and burned out the connection. A Chevy mechanic told me this has been happening to MANY Chevy products. I had to buy a new part and plug assembly with new wires, about 100 dollars, and I spliced them together. It was an Easy fix, but I shouldn't have had to do it :(

SOURCE: 2006 hummer h3 has a leak on passenger side under

My 06 was leaking during rain also. It turned out to be the sunroof. There are two drain tubes in the front of the sunroof that run the water down the corners to the ground and two drain tubes that drain water out the back corners. The water would seep around the glass, which is expected, but both of the tubes on the front of mine were plugged, and the water would overflow behind the dash and fill my floorboards. If my H3 was leaning to the left during a storm then the drivers side would be full of water. If leaning right, then the passenger side. I had to open sunroof and blow compressed air into the drain holes to clear them, but be careful, too much air will separate tubes from sunroof and then you will have to remove the inside paneling around sunroof to get to tubes and reconnect. You may only have one side plugged. you can test it by opening sunroof and pour a little water in the small catch pan in the front of the sunroof and see if it drains as expected (to the ground under the firewall on left AND right side). You can see the holes in each corner of catch pan to drain the water. Plug one with your finger, then the other to find the plugged side. Good luck!! Hope this helps!!

2006 Humer H3, Won't start and electrical resets itself


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.

I have a H3 hummer but my truck battery keep going dead and my battery is new and alternator is good


The batteries they put in the trucks from the factory ****. I went through 3 of them under warranty, they lasted 6 months a piece.

I did research to find who made the factory model. I found an alternative manufacture and bought their battery and I have not had a problem sense. I bought a Duralast from auto zone.

Ac in 2006 hummer went out without warning


I am a Service Advisor for a Hummer Dealer. I can tell you that we have seen some of the 06 h3's with the same problem you are having. The blower motor resistor and harness will probably need to be replaced. The connectors on these have a tendency to melt. If you are still in factory warranty, it will be covered under your warranty, otherwise at the dealer the repair runs around $650.00 parts and labor. Hope this helps.

H3 cd player


Well i feel like a complete *********. The load button and eject button are on the same button but seperate if that makes sense, much like a forward/rewind button. So i finally just took a minute to really look at the situation and as soon as i hit more to the left of the button (load side) it said load cd now and poof problem solved.

thanks anyways!
