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.

The ventilation system stopping blowing air. I went online and did some research about this and found that many others had the same complaint and how to diagnose it. I opened up the area under the glove compartment and found that a resistor was burnt up. This appears it could have been a very dangerous situation if it had caught fire.

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.

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. Service done by whitehead Chevrolet of truth or consequences, nm. The service mgr said this was a common problem.

HVAC system fan blower works intermittently...sometimes the fan blower doesn't work or stops working altogether causing a major problems on cold or foggy days when you need the defrost to work. Reported this to GM dealer but no repairs made.

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! updated 08/20/09.
