2002 Chevrolet Trailblazer ProblemsFuel 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.

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.

2002 Chevrolet Trailblazer QuestionsWhy can I turn my drivers side door key, but it will not unlock? (1 answer)
I can not get into my car! I only have one key hole and it's on the drivers side door. Its not cold out so I don't think it's frozen but I can not open my door.. The key turns both ways but feels very loose and will not unlock. Any ideas? Thank you.
Won't even turn over, nothing. Starts fine for a couple days, then won't start. Starts when jumped after the 4th or 5th try. Thought is was security system problem, and tried resetting that but still having problems.
