3-4 months ago my A/C unit started making a loud noise with a burning smell when I would put my A/C switch on level 3 or 4. It would sound like if my A/C unit was going to blow up. The next day I received a recall letter from the hummer company descriving the same symptoms my h3 A/C unit is having.I called the hummer company and asked them how long is going to take for them to fix this problem they stated in a very rude manner that they will fix it when ever they get the part. This is the worst experience ever I . I asked them if it can take more than a year and they responded we do not know. I got very upset because its not fair that I spend a lot of my money to buy my h3 and if its a recall why they dont help me to fix my problem, I explain to them that the weather in texas is very hot and I been without A/C since and they dont care. This is not fair please help me out. I dont even know what to do anymore, please advise. Help!!!!!!!!
2007 Hummer H3 electrical complaints
Page 3 of 4: complaints 41 to 70 of 76, newest first, as owners wrote them.
Today I am reaching out to you for your help. This letter is in reference to the gm recall on the hummer h3 A/C module resistor that was issued in july of 2015. My wife and I have reached out to gm on multiple occasions with no resolution in site. I ask that the federal safety agency demand gm establish a timeline for the completion of a corrected part and that gm provide an adequate alternative option to gm customers faced with this issue until the part is available. My concern is over my well-being as well as my families. On monday august 31, 2015, I was driving home from work when I noticed a burning smell coming from underneath my glove box. After I pulled over and examined closer I could see the issue was from the A/C module resister that was recently recalled. The resister had burned through part of the harness attachment. Upon reaching out to gm, they stated I only had two courses of action: 1) to replace the part with another faulty part (which I would have to pay for) and hope that the part does not short / catch fire before they are able to come out with the corrected part (which would be free). 2) wait for a corrected part to become available. The main issues with the second option are that gm has no timeline for the completion/availability of the corrected AC module resistor (customer service said anywhere from 1 month to multiple years). This would leave the customer (without heat or A/C) for an extended period of time. My current work commute totals 2 hours every day. Where I live this becomes problematic due to severe summer / winter climates (as I write to you there are heat warnings in effect). Gm has known about this issue since 2009, yet they failed to act. Now the consumer is forced to face the consequences of their ill planning and neglect while gm continues to act inept. Please help gm realize that gm customer lives matter.
Tl* the contact owns a 2007 hummer h3. While driving at approximately 40 MPH, the contact turned on the air conditioner and heard an abnormal noise and smelled a burning odor.

No air was coming out of vents, found the problem was faulty wiring with the resistor and wire harness blower motor both were burnt and smell of something burning.
Vehicle would not start called dealership where car was purchased - replaced ignition switch after diagnosis. Since then have had repeated episodes of vehicle ignition/electrical just shutting completely down on different occasions. I could be sitting or approaching a stop light vehicle shuts down upon taking off or idling down, vehicle also shuts down when making turns as well. It occurs so infrequently and has no pattern but it is indeed a safety concern because I have to put on the flashers and take time to restart the engine all before someone runs into me.
Engine check light came on for very short period of time then went out. About a week later it came on again. Went to chevy dealer who ran a quick code check which indicated the number 5 cylinder was misfiring. The chevy dealer indicated the engine/power train warrranty had expired and the problem could be from injectors, plugs, coil and valves. Initial computer check would cost $135. Vehicle is sitting in my garage awaiting money to get it checked.
The HVAC blower motor resistor connector located under the glove box was burnt, the red plastic on the harness was melted. The reason I became aware of this is because the blower quit working. I looked this up online and found it is a common issue. I feel anytime you have the potential for a fire there should be a recall. I feel it is fair to assume the new resistor and wiring harness will do the same thing since it is the exact same design.

I have a 2007 h3 hummer with 81000 miles. This past summer I got into my truck and put on my air conditioning on high. Nothing came out of the vents. Blower motor wouldn't even move. I did some research on the topic and it all lead to a burnt out blower motor resister. I had purchased a new one and replaced it to find out that there was a small fire in the plug from it getting to hot. This is a common problem with the h3. I talked to gm safety and they won't do anything and bout it because it's out of warranty due to age and miles. There is no reason for this not to be a recall issue. No blower motor means no defrost on your windshield. Due to cold winters in new york you need the defrost. Now my trucks blower motor works when it wants to due to faulty wire harness in truck. I have pictures of the plug and old resister. Thank you
Air blower for air conditioning and heater stopped working because melted plastic on resistor also fried wiring and harness needed to be replaced.
My son was driving his 2007 hummer h3 when it caught on fire. It was an electrical fire started on the passenger side in the dash. He didn't know it was on fire until he got out of the car to go into a restaurant. He didn't even smell anything burning and had only been driving around 5 minutes. People were pointing at his car telling him it was on fire. The local fire department got to him in 3-4 minutes. The hummer h3 was totaled out because of the fire. The car had approximately 64,000 miles on it and was in excellent condition.
Just had my hummer in 2 weeks ago at the gm dealership to have the ignition switch replaced. Had been dealing with it stranding me and my kids for 10 minute periods long enough. ( sometimes longer) while it was in there we also had to get the radiator replaced due to it being cracked. Now 2 weeks later my check engine light and traction light have come on. The traction light saying service sab system. After reading all the hummer problems I can not believe that there was not a recall on both the ignition switch and radiator. The ignition switch being faulty put me and my kids in situations in places for long periods of time that were not safe and at times we were very cold since we can have below zero weather in colorado. The ignition not recognizing the key causing the anti theft system to activate is recall issue and gm you should be taking responsibility for this!!

Was driving in a small town and the vehicle just lost all power with no warning. It cost me over 600.00 to get repaired and I'm thankful I was not on the highway going 60 or 70 and I'm thankful there was no vehicles behind me. Also the key won't come out of the ignition after I drive it for a while and this wears down my battery and I have to get a jump. Has there been any recalls or other complaints about these problems.
Fan blower resistor burnt up and melted wiring harness electrical seat button that controls position and heat turns on due to the side plastic seat molding that flexes when you sit in the seat.
My car began show the passlock disabling system light and then failing to start. After starting, it would then show the air bag warning lights for a period that might be several minutes to several days before going out again. This cycle happened at random times disabling the auto without warning and in some dangerous situations. It is a well known and publicized problem that gm has chosen to ignore. I have solved the problem by having passlock disabled and ignoring the air bag warning light with the assumption it is a false warning. These recent events have me reconsidering that action, but the cost of having the problem rectified would be more than I could afford.
Tl* the contact owns a 2007 hummer h3. The contact stated that while driving 25 MPH, she began to smell plastic burning under the dashboard.

Here are multiple issues well documented across the internet of hummers having and issue with these resistors, as well as chevy colorados. My blower quit a few months ago, and the resistors and wiring harness are melted to the point of charring! The federal safety agency needs to investigate this or are you waiting for an actual fire to cause gm to fix this issue?
The anti-theft passlock system is faulty and will not let me start my car. It has happened twice since I got the car in december of last year. Going on-line to see what to do about it made me aware of the overwhelming amount of gm car owners that this has affected. Some being stranded for hours and days of not being able to start their cars due to the faulty passlock system. It is happening to all makes and models of gm cars. I called gm and they weren't interested in doing anything about the problem unless you force them to. Please check into this and help those of us who get stranded in places (sometimes scary places) because our car won't start. Thank you.
Driving down the road at 20 degrees outside and the heater fan quit. Had cut out a couple times before and come back on.
Tl* the contact owns 2007 hummer h3. The contact stated that the ignition failed to recognized the key, causing the anti-theft system to activate. The vehicle was taken to the dealer several times who was unable to diagnose the failure. The manufacturer was made aware of the failure who did not offer any assistance. The vehicle was not repaired. The VIN was not available. The failure mileage was 40,000 and the current mileage was 98,000.
I was in a parking lot, I started the vehicle and turned the air conditioner on. It worked but suddenly stopped blowing air. I took it in and it was diagnosed as the blower motor resistor had gone out. I had it replaced only to have the same thing happen again one week later but this time I smelled something burning. The wiring had burned going to the resistor. The technician informed me that this happens often with these vehicles and he doesn't understand why there isn't a recall. After researching the problem, I found that this is a common and potentially very dangerous problem with the hummer h3. There needs to be an investigation and recall so that no one gets hurt. If I had a passenger in my vehicle at the time of this incident, they would have received burns on their feet from the wiring malfunction and burning. I again am having to pay to get this corrected.

Malfunction of air blower for air con and heat, melted plastic on resistor, rendered in opt.
I am the original owner of a 2007 general motors hummer h3. The auto has been well maintained and professionally serviced by a gm dealership. The vehicle has 53,600 miles and is in perfect mechanical condition except this recent issue with passlock security which has rendered the vehicle unreliable and a personal and public safety hazard. The vehicle is less than 30 days out of warranty and dealer will not repair under warranty. In recent weeks, the passlock security light began randomly illuminating while driving. This light could extinguish on next start or stay illuminated through several starts. Two weeks ago while returning from a trip later at night, the vehicle was disabled and failed to start in an airport parking lot. The passlock light continually flashed and the engine cranked, but without starting. A tow truck was called, but by the time it arrived, an attempt to start the vehicle was successful and the light was extinguished. This has happened at least twice since in less inconvenient and less dangerous areas. The vehicle is unreliable and unsafe. I cannot trust it to allow my wife to drive it for fear if her being marooned in a dangerous situation. The dealer has indicated it might be several hundred dollars to repair this problem and was well aware that it was a widespread problem with gm autos. There are hundreds of similar complaints on the internet and yet there is no response or attempt to remedy this situation by the manufacturer. I am a senior citizen and need to rely on my vehicle, but cannot rely on a vehicle whose security system can disable the vehicle at any random time. As my representative, I request the federal safety agency address this with the manufacturer and remedy this safety concern.
