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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

CarComplaints.com Notes: The Trailblazer emerged from an "upscale trim line" of the Blazer, but there's nothing upscale about its transmission problems or its wonky, unpredictable headlights.

A/C is running ok then, it starts blowing warm air. Outside temp display drops quickly until it reaches +28 deg.F. (note that outside temp is +85 deg.F.) outside temp display starts rising slowly. When crosses +30 deg.F, A/C starts blowing cold air again. Outside temp display then sticks at +50 deg.F and does not go any higher.

A/C initially operates normally. Outside temp display then begins decreasing. When displayed temp passes +25 deg.F, A/C no longer produces cold air. Outside temp display continues dropping to -34 deg.F. after ~5 minutes, outside temp display starts rising. When temp display passes +25 deg.F, A/C starts producing cold air again. Outside temp display reaches correct outside temp. Occurs intermittently (I.e., once or twice a day -- or not).

I brought this SUV from the dealership and I started having problems with it a month after I brought it. The car air conditioner stop working and the transmission was making a horrible sound. I took the car to the dealer to get fixed three times. All the times I took the car it came back the same way that I took at first. I also took it to a different dealer to get fixed and they also didn't fixed it. I want to cancel this SUV purchase. Mainly because even before T brought the SUV the salesperson at the dealer added $5,000 to my income so I could qualify to get the SUV, but that was completely a lie. Right now I'm having many problems at work; that's the main reason I want to cancel the purchase of this SUV, which is just giving me many problems.

2002 Chevrolet Trailblazer experiencing problems with the air conditioner as well as with hesitation. Car hesistated every time the consumer tried to pick up speed. Also had problems getting car started at times. Had to play with the key on the passenger side door to start the car. The dealer couldn't duplicate the problem.

2002 Trailblazer has air conditioner problems. This is the third time this problem surface. It would produce hot air when the outside air temp is @mid 80's and the vents are producing extremely hot air when the temp selected (auto) to 74 and this time the driver air works fine but extremely hot air is coming out of the passenger side. Does not matter what settings are selected. Dealership states that this is a recurring problem with the Trailblazer air conditioner. Something with the sensor.

Electronic exterior rearview mirrors and power seat engage and operate by themselves. Dealership cannot fix the problem. The memory for the mirrors and seat would not keep their position. When the consumer entered or exited the vehicle the systems would reset to a new position. Occasionally they moved while the vehicle was in motion. The dealer has replaced many components but the problem still exist. The check engine light illuminated. The dealer replaced the oxygen sensor. The A/C control mode button became stuck and was noisy. The dealer replaced the A/C module head. The left windshield wiper chattered and skipped. The dealer replaced the wiper insert. The 4WD switch fluctuated between 4wh and A4wh. The dealer inspected the vehicle and replaced the transfer case select switch.

The vehicle stalled intermittently while driving. The dealer was unable to determine cause of problem. The vehicle periodically shut off while in the idle position. The vehicle was delivered to the service department on several occasions to have the problem identified and corrected. As of 07/07/2003, the vehicle continued to have problems with loss of power and the service dept. Has yet to determine the problem.. the air condition developed a foul odor which was present after the vehicle sat in the sun, the odor was detected immediately after the vehicle was started and the ac was turned on, the vehicle was serviced times and then the problem returned, the air condition now takes a long period of time to cool the vehicle and produce cold air.
