Chevrolet Trailblazer Problems

Cooling Fan Clutch May Fail Causing Noise and Check Engine Light

The cooling fan clutch may fail causing excessive fan noise and/or the Check Engine Light to illuminate.

Fuel Level Sensor Failure

The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.

On certain 2005 - 2007 vehicles, General Motors has provided a special service policy covering the fuel level sensor, agreeing to pay 50% of the repair cost. This coverage extends for 10 years or 120,000 miles from the original "in service" date of the vehicle. Please contact your local GM dealer for more information.

AC Blower Inop Due to Failed Resistor

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.

Chevrolet Trailblazer Recalls

Driver's Door Window Switch Shorts And Catches Fire

The driver's door power window switch module may get contaminated with liquids causing a fire hazard. Dealers will replace the driver's door switch module free of charge to resolve the concern.

Headlights & Daytime Running Lights

These vehicles are being recalled because the headlamp driver module (HDM) can overheat and fail. This will cause the headlights and daytime running lights to stop working. Loss of this lighting will affect the ability of the driver to see the road and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash. The remedy for this problem is still under development and not yet available.

Power Door Locks And Windows Do Not Operate

The module that operates the power window and lock switches can allow moisture in, causing corrosion that can lead to a short circuit. This results in window and lock functions not working, and creates a fire risk. Dealers will inspect and replace affected modules free of charge to resolve the concern.

Chevrolet Trailblazer Reviews

This is the worst vehicle ever made. It's worse than the ford pinto, the Chevy corvair ( which is exactly what this piece of garbage is like ). I repair one thing and an hour or less later something else goes wrong. I keep hoping the thing would catch fire most of the time. It always breaks down when it is cold outside also. I will never buy another GM product again.
I am 57 yr's old and always drove a Chevy but my 2003 Chevy Trailblazer is a big disappointment to me, on Chevy's part. If it is'nt one thing it is something else. I am going to get this POS running the best I can and it is going to another fool like me for buying it in the first place.
Bought my 2006 Trailblazer in 2010/2011 with 68k miles on it and initially liked it (first two years), but four years later (127k miles) nothing but trouble. This Chevy is a piece of JUNK IMO. Terrible design, cheaply built, junk parts, etc. I get it the vehicle is almost 10 years old, but come on. Does every part HAVE to be designed to fail after 100K when you pay 30+ thousand dollars bran...
