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 blower motor stops working sometimes on my 2007 Hummer H3. Sometimes you can turn the ignition off and wait a little while, then restart it and the blower starts working.


I had the same problem and sloved it with the help of google images, hummer blower motor resistor. Under the glove box the blower motor resistor can be found. It comes loose and the blower will work at times. When I reached under and pushed the connector in, it works fine. It was fixed within minutes. I am a gal with a Hummer and save myself a huge dealer bill. Good Luck!

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.

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.

check the blower speed control, it most likely burned out, also jump battery power direct to the blower and see if it runs, if it does the speed control is defective, if it doesn't the blower motor is toast.

2006 H3 Hummer Ac/Heater fan motor will work great and run, the next time I start and drive not come on at all. Then sometimes after driving about 15 min just kick on and run and do great.


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.
