Description of the complaint: the blower on my 2006 hummer h3 stopped working while driving down the highway burnt plastic smell when the blower stopped. But the blower never worked again. I found that this is a huge issue for not just hummer owners, but other gm vehicle owners. The resistor and plastic clip were melted together this resistor for the AC blower is located right under the glove compartment damage danger this issue poses.

2006 Hummer H3 electrical complaints
Page 4 of 4: complaints 71 to 96 of 96, newest first, as owners wrote them.
March 2012 - hummer locked up and will not turn over .. Towed it to dealership .. They replace key ignition all of april my hummer will shut down .. 3 times had it jumped ... Found out it was not the battery .. I was driving when the hummer locked up .. It was very scary ! 68,000 miles only ! Currently at the dealership again 2 twice in less than 2 months.
Right rear tire tps gives false and intermitten readings, can not turn radio/cd player completely off, drains battery. Dealer says system is defective and needs to be relaced at a cost of $1000.00.
Very very common problem with gm products and excessive problem with h3 heaters. You smell something burning in your vehicle then your heater fan starts fluctuating and ultimately stops. There are reports that the dealership will fix the burnt plug, but it won't fix the problem, it'll burn up again. Now I have no heater in january in ohio this should be a recall !!!!!!!!!
11/02/11 smell of something burning looked under dash blower resistor and plug melted together had replaced on 12/11/11 smelt burning plastic again had same problem blower resistor and plug melted again from what I understand it is a on going problem in this vehicle gm should be responsible in fixing it before there are major fire damage or a death.
The blower on my 2006 hummer h3 stopped working while driving down the highway and we smelled a burnt plastic smell when the blower stopped. The smell eventually went away, but the blower never worked again. I found that this is a huge issue for not just hummer owners, but other gm vehicle owners. The resistor and plastic clip were melted together and when disconnected, fire damage was evident. This resistor for the AC blower is located right under the glove compartment and luckily nothing flammable was close to this when is blew while driving down the highway. I also have pictures of the damage and subsequent danger this issue poses. Other posts of people seeing this issue.

On october 30th I smelled a faint scent of something burning inside my vehicle, but could not find anything. November 1st was our first cold morning so I started my car, and had no heat. The system wasn't blowing, but the heater A/C controls were lit up. Since I am a mechanic, and have knowledge I went right to the fuse box in the engine compartment. The fuses were ok. I then went to the blower resistor pack which is located under the glove box. The orange power wire in the harness was burnt up pretty good, and the terminal molded into the harness pack was also burned up pretty good. I then went online to google this problem to see how common it was, and was surprised to see how many complaints there are about this problem, not just regarding the hummer line, but within gm vehicles itself. I called the service tech where I have my work done, and he was very familiar with this failure.
As I was driving to my office from a lunch break, my A/C and ventilation stopped working, I turned the on and off dial and air never came back on, shortly after that a strong "burned" smell came from the glove box of my vehicle, I pulled over and noticed a little bit of smoke coming from underneath the glove box. I did some research on the interned and discovered it was a burned out "vent blower resistor" (AC delco part# 15-80647) I have since replaced it but it still not working. I have the burned part if ever needed, I must say I don't feel at all safe with a situation like this as it has never happened to me. I decided to include my complaint as I have seen many people with the same problems on this vehicle, a fire is eminent and should be prevented.
A/c heater motor resistor overheated causing smoke throughout the passenger compartment on the highway this is the third replacement of this part, the wiring overheats and melts the connectors this is a very common problem on hummers of all types. My sister owns an h3 as well and has had to replace this twice on her 2007 model h3 due to overheating an melting the connector. Is general motors going to wait until there are numerous fatalities or vehicle fires to rectify this ? A fire in the passenger compartment while at highway speeds is dangerous to say the least
Overheated and melted resistor and wiring harness for the HVAC blower motor on a 2006 hummer h3. This has happened to my vehicle and a friend of mine. Also many owners on the internet have had this same problem. It is so prevalent that many parts suppliers are advertising the parts for sale.
Purchased 2006 h3 with 58k on it. At 61k the A/C blower would increase in speed for no reason then go back to its setting. At 62k it stopped blowing for no reason. Online search of h3 A/C blower issues gave me a place to start looking. Fuse was ok, checked resistor pack (pn 11221007.011) under dash and found pin "a" melted with sign of recent electrical fire due to shorting out. The orange connector on the harness was also melted. Further online research of this issue revealed that it is a "common occurrence". I called dealer and was told "they have never heard of it". I purchased resistor pack, connector, and pins then changed the component myself. Works good so far....
I have a 2006 hummer h3, every few weeks or so the motor will turn over but will not start. I let it sit for a while and then it will start. I have taken it to both the dealer and another mechanic but neither can find anything wrong with it. About 6 months ago, I got a new battery thinking that would solve the issue but it has not.
Heating/ AC fan blower harness burnt up. A very common problem on an hummer h3/.
I bought my hummer h3 in august of 2009, used at a chevy dealership that is a sister store of chevy/hummer dealership. My 2006 hummer was fine until the cold weather hit. The first incident occurred around the first week of november. I was leaving to go to a friends house around 9:00pm I went outside however to turn my heat and my heated seat on, and about five minuets later I went out to my car to leave and my car was freezing with no fan motor on at all. After staring at my fuse box and reading the crappy owners manual for around and hour, we came to the conclusion that no fuses had been blown. The next day I drove my vehicle to the chevy garage. The service man checked it out and said that he would take care of it. A week later I was driving back to pick up my hummer up. On the way home from the dealership I got about five miles up the road and my car was filling up with smoke. I then returned my car to the dealer. A week later again I picked my car up, drove fine and get this I even had heat for about a month. Until it was around christmas and the same thing happened, dropped my car off and a week later picked it up. Two weeks later and it was around the middle of january, the same thing happened. I took the car to the garage yet again and the fixed the same thing that they have been fixing, no change and no investigation on the problem. The fifth time happened around five or six days after I picked my car up from the previous time getting fixed, only this time they brought it to their sister store the one with the hummer certified technicians. I finally got my car back two weeks later. Then around the last of the cold weather it happened again it was the beginning of april. I got it back and had no problems, not even with my A/C, which I run all summer long. Now this november was the first time it happened again since last april, and it's going to be the last.
Heater A/C fan motor quit. The dealer repaired the link as he said it had gotten hot and burnt out. I can't find invoice at this time, but believe it to be around $90.00. Service done by whitehead chevrolet of truth or consequences, nm. The service mgr said this was a common problem.
I own a 2006 hummer h3. My fan blower quit working. Upon investigation I found the blower motor resistor and the connector to be welded together. I had to replace both items because they were melted together. This has to be a fire hazard and after I googled it to figure out how to fix it I was shocked at the number of people who have had the same problem. I can not believe this has not been a recall issue.
On may 29 2010 I went to the store around afternoon and came back from the store I started my hummer 2006 h3 the car started and I look at the indash and no light came on and I drive around the parking lot to see if the in dash light come on and I park the car and turn off my ignition and turn it back on still the same no light on my indash and I was scare to drive it out on the road because I don't see how fast I was running or the car might die out on me when im driving and I was thinking to myself this is very dangerous because this could cause an accident and I was mad I drove home and about 3 or 4 minute later the light came back on when I was driving and I was wonder what could cause this to happen or did my electric wire short circuit and my truck is 4 year old and barely driving it. So could you please investigate on this, because it happen to me it could happen to other hummer h3 owner . So please act now so no one get hurt and to prevent from happening and last month my two door on the passenger side front and back has a squeaky noise everytime I open the front and back passenger it make to much noise and I wonder is this how hummer make there quality truck like this and my truck is only 4 year old and still brand new.
Last week I was driving locally home when my h3 cab filled with smoke blocking my vision and the A/C blower stopped...I nearly drove into a tree...if I had been on the highway at speed, I would be dead. I took the car to a local shop, as close as I could get...anyway my dealer was shut down as gm went into bankruptcy. The mechanic found that a wiring harness connector burned out, creating the smoke and cutting the blower off (see photos). I reported this to gm, asking them for refund of costs and to investigate this serious safety matter. They refused because I am out of warranty! I believe they are covering up a serious manufacturing flaw...when the mechanic phoned gm for the wiring harness section involved, they had it in stock ready to go...evidently, gm knows of this flaw. If this problem is not taken seriously, someone will be killed by it! *tr updated 08/20/09.
Fire started in back of my glove box in my hummer h3.
Tl* the contact owns a 2006 hummer h3. While driving at 70 MPH under normal conditions the oil and air bag warning indicator lights turned on and the vehicle began to decelerate. The contact turned the ignition off, and on within 5 minutes, drove the vehicle and failure didn't reappear. The dealer was unable to diagnose the failure. Also, the dealer stated that it could be an electrical failure but they couldn't confirm it. The current and failure mileage were both 13,000.
I have two 2006 h3 hummers both with the 5 speed manual transmission. Upon acceleration from a stopped position in first gear, depressing the clutch for the shift into 2nd gear the engine rpms revs to about 4000 and stays there. Shifting into 2nd gear & releasing the clutch the rpms drop back down. Accelerating to about 3000-3500 rpms, depressing the clutch, again the rpms climb to around 4000 and stays there. The same thing occurs during up shifts ... This has happened no less than 7 times on one h3 and 5 times on the other h3. The hummer dealer can find no stored codes, and can not duplicate this. Gm has been notified, but nothing has been done to repair this problem because the dealer can not supply defect codes. This has been going on since august '06 with no end in sight. I have asked the ecu be either reflashed or replaced and was told it was too costly to just put parts in without any codes. I believe the software could be corrupted. And is not aware anything is wrong. Thus there are no codes.
Vehicle locked up while I was driving - unable to start and had to have towed to dealership. Serious electrical problems for the 2nd time.
While driving vehicle locked up and shut down - could not restart and had to have the vehicle towed to the dealer.
Vehicle had an engine miss fire that required replacement of the head. Miss. Returned shortly after repairs. Dealer said there was no miss. Vehicle filled up with water during a rainstorm. All interior had to be removed and dried out. Electrical problems occurred that required four batteries over 12 months. Dealer stated it was my problem, because I had a small inverter for computer. Sold the vehicle to the hummer dealer at a loss of $15,000. Hummer refused any assistance after first stating they would.
Nuisance - key stuck intermittently in ignition upon turning off. Safety problem - key can always be removed with transmission in any gear position.
Dt*: the contact stated while driving on 5 separate occasions the message center read, power reduced and asc failure. The vehicle would not exceed 35 MPH during the power failures. The vehicle was pulled off the road without incident and towed to the dealer on 3 occasions. The other 2 occasions the vehicle was driven to the dealer. It was determined the computer that controls all electrical functions failed; however this did not correct the problem. The manufacturer was alerted.
