Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

H3 5-cyl

  • 79,000 miles
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

H3 5-cyl

  • 76,500 miles
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.
