The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

2008 Chevrolet Trailblazer Problems
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
Electrical power may be lost to the interior of the vehicle due to a blown 125 amp fuse located at the under hood fuse box. This fuse can blow if jumper cables are connected incorrectly. Replacing the blown fuse will commonly correct this problem.
GM recommends replacing the engine coolant at 100,000 miles; however, our technicians tell us that the coolant may become contaminated and require a complete cooling system flush every 60,000 to 70,000 miles.
Brake fluid can become dirty and may cause problems in the brake system; it should be flushed every 60,000 miles.

2008 Chevrolet Trailblazer Reviews
I purchased this SUV with 38,000 miles on it. I now have 129,900 and it is still going strong. I am just now needing to replace the front brakes. My gas milage on the hiway averaged to 18.2 mpg. Have not had to change spark plugs yet, but did remove and regapped them. I an sorry they quit makeing the TrailBlazer. It is great for city and some country driving, with good groung clearance. I have the 4.2L6 engine.
Without a doubt this is the worst vehicle I have ever bought. In addition the chevy dealers are the most uncooperative people I have ever encountered. They either don't know or will not be honest about your situation. This car is a electrical nightmare.
exaust pipe from engine to muffler , pipe broke by engine called chevy dealer told it would be $900 to replace. called several places was told only could get it from chevy. called different chevy dealere got a new story because i had less than 80,000 it was under warrenty because this pipe was part of converter.
I have the 5.3 v8 ,and completely satisfied with it. As far as I am concerned it's better then the inline six, and better on gas then the SS. I plan to keep it at least 7 years. I hate the auto ac controls, and would prefer the manual settings. It never seems to get air flow direction right.
I have the SS model and expect it to be my retirement car. I love this vehicle. It is like driving a sports car with extra room. It handles very well and has a lot of the comforts you would expect in a luxury car instead of a "muscle car". The suspension is automatically adjusted by a sensor valve and is a little stiff but it also tows well. No rattles or major problems after 12,000 miles. I did have to take it to the dealership to replace the rear Chevy Emblem as it was working loose. From slamming the rear hatch maybe? No rattles or strange noises yet.
