2003 Chevrolet Trailblazer Problems

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.

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.
