I just fixed this exact problem in my 06 H3. It turned out to be the resistor pack in the blower motor. I had to replace the resistor(it shorted) and the small harness that spiders over the blower motor assembly(it melted). It was an easy fix and only about $50 in parts that you can order form any GM brand dealership. Check out the link and and look at parts #3 and #4. Good luck!

If the fan does not blow,yes check the fuse first,if it is ok,then remove the wire plug off the blower motor and check for voltage at the plug,if power is present the blower moter is probably bad.One more thing check for power going into the blower switch sometimes they go bad.the actualy burn out causing a open .

This issue is very common. Seems like it should be a recall. I am no rocket scientist but melting plastic and wires should not be a common problem. i urge everyone with this problem to report it to nhsta.

Awesome! The harness fixed my problem! Repair shop wanted to charge me close to $500 to replace motor, harness, and resistor. What a joke!

My problem was same as above. My connection has a hook shaped pin running through it that needed to be removed before prying it apart. One side of the connector (side opposite of orange wire) will have a tiny white point of this hook shaped pin. You can use an un-bent paperclip to push this pin through and then it can be pulled out by the hook shaped end.

I fixed my connection by removing the burned plastic section of the connector with some side cutters and pressed on a new blade connector. That way It's a 10cent fix. I figure if GM can't replace it and guarantee it won't happen again, I'll take my 10cent McGyver fix and see how long it last. The resistor pack was undamaged, just browned from heat. Thanks to all in this Fixya forum for the help. You guys totally rock posting this.

No this is a problem that gm needs to address , 95% of this problem is coming from blower motor resistor and the connection is over heating and failing ..check your resistor if you see burnt wires that is the problem....but if wires are not burnt and you cant get connection apart , then the wires are burnt inside of the connection , try pulling the trasistor apart from the blower motor..one small tab holds them on if it comes right off check for burn marks insidethe connector..if it doesnt come right off it is melted together from over heat

    Identical problem here on my H3T 2009. Only when removing the connector from the resistor pack, there is also a white pin running through the connector. The end of it protrudes though one side as a small white toothpick sized end. push it through with a paperclip and pull it out. it will have a hook on the other end. Then you can lift the large tab running down the center of the connector and pull it apart. I cut the bad section off of the factory connector and pressed a blade connector onto the resistor pack and fixed mine for 10 cents and labor. the resistor pack was undamaged. Connector was fried. We'll see how long it lasts.

H3 A/C Problems. New resistor...now what??


I had the same problem. I fix it my self. This is what you look for, is your a/c blower working when you turn the fan on. If a/c light come on but nut the blower fan. Then under passenger dash you will see orange plug. It's held in with 2 screws. Remove 2 screws and pull resistor out. Disconnect orange plug and look at orange plug and the resistor if burn need to replace the resistor and the orange connector. That's your problem. Now if your blower works but no power to a/c switch and you instrument nobles has no lights. Then it's a fuse check #48 and # 57 fuse that controls that Troy

Heating and air conditioning just stopped working. No air. No sound. Dead. Looked at the fuses and they were all fine. 2006 Hummer H3


Iwould look blower motor resistor, that is the most common problem, if the fuses are good it must be the motor or the resistor and i would say the resistor, the resistor is what controls the speed of the blower, this is located on the heaterbox, if you follow the wires that plug into the blowermotor it will lead you to the resistor. good day.

The airconditioner only works in my 2006 H3 when the car is physically moving over 25 mph. If it is going slow or idling there is no air coming from the blower/fan. When it does blow it is only on a low...


There is a HVAC relay and FUSE in the under hood fuse box, have you check both of these? If the blower works on any speed, the blower is good. You say it blows on lowest speed? The blower speed resistor is mounted on the blower housing. The HIGH SPEED BLOWER RELAY is mounted on the blower motor. You may have multiple problems but check fuses first, if all is OK, then a qualified repair shop will need to check further. You do NOT need the whole A/C system replaced. If it does blow cold, thats good, you just need the blower working.

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.

(06 Hummer H3) Blower not working, Clutch Keeps blowing fuse.


I assume you've fixed this already given that nearly a year has passer by, but if others experience this, it may help them. Under the dashboard on the passenger side there is a Fan Blower resistor attached to a red connector with 5-7 colored wires. Its held in by two simple screws. Disconnect the connector and inspect it for any burn marks(usually the last orange wire at the end). If this is discolored go to the nearest GM dealer and by about $70 worth of parts. The blower resistor, the red harness connector and the clips that go into the connector. Job takes under an hour and would be rated at novice-intermediate. Advice: set the passenger chair back as far as possible. Remove the harness clips carefully so as not to break them. For more workspace you can easily pull out the plastic facia on the right hand side, it easily slips out from under the foot rail, do not be intimidated there are no hidden screws. There is also a relay down there; a small black box held in by one screw, you might as well change this while you're down there. A dealer may charge as much as $400 for this simple fix!

Cooling fan is not pushing air out.


That could be the blower motor resistor or the blower motor
