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.

Print this page Notes: Carrying the not-so-proud traditions of its 2002 predecessor, the 2003 has a handful of instrument panel malfunctions that can leave you guessing your speed, engine temperature or how much gas is left in the tank.

2003 Chevrolet Trailblazer Owner Comments

problem #5

Aug 192003


  • 5,457 miles


The contact owns a 2003 Chevrolet Trailblazer. The contact stated that upon entering the vehicle she smelled a foul odor which she described as mildew. The vehicle was taken to an authorized dealer who installed a delayed blower. Approximately 2 years later the odor returned and the battery began to drain rapidly due to the delayed blower which continued to function when the vehicle was turned off. The vehicle was taken to an authorized dealer where a module within the delayed blower was replaced twice. The contact stated that a few months later, the blower stopped working. The vehicle was taken to an authorized dealer to replace the module inside of the blower. Approximately 2 years later the contact stated that the wiring within the delayed blower burned out and it was replaced. The failure had become progressively worse over time. The failure mileage was 5,457 and the current mileage was 140,000.

Spare tire carrier not operational. Inability to change flat tire unsafe and costly (of course, to the owner). General Motors poorly re-designed spare tire winch includes plastic housing for cable that deteriorates in the severe service area of a motor vehicle. Previous designs did not involve the use of plastics in the external mechanisms. Mine failed leaving me with a flat tire and a perfectly good spare that I was unable to lower from the rear undercarriage of the vehicle. Makes no sense to replace the winch with another of the same design leaving most people no option to either not carry a spare or carry inside the vehicle either unsafely anchored or not anchored at all becoming a projectile in the event of an accident.

I have a 2003 Chevy Trailblazer that I have been having problems with the A/C since the date of purchase. I have taken the vehicle back to the dealer and the continually advise me nothing is wrong with the A/C. the A/C blows hot all the time, for that matter the blower vents omit hot air continually. I have made every effort to have the problem fixed without any assistance. This seems to be an ongoing problem with the 2003 model.

The contact owns a 2003 Chevrolet Trailblazer. While driving approximately 5 mph the vehicle began making a loud noise. The contact pulled over and noticed that the rear driver's side tire was flat. While attempting to remove the spare tire the hoist failed to crank to release the spare tire. The serial number for the crank was not visible. The mechanic stated that the wires for the hoist were crossed. The current and failure mileages were 48,000.
