2003 Chevrolet Trailblazer Problems
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 cooling fan clutch may fail causing excessive fan noise and/or the Check Engine Light to illuminate.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.
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.
The variable valve timing camshaft actuators may stick due to dirty engine oil or a faulty control solenoid. A sticking actuator may cause a rough idle and the Check Engine Light to illuminate. Our technicians tell us the engine oil should be checked to make sure it is clean and at the proper level before replacing any parts to correct this concern.
One or more of the rear lights may be out due to a failed light socket plate. Our technicians tell us some 2002-2004 models were recalled for this issue. For more information on this recall, please click here»
The CD player in the radio may fail. Our technicians tell us that the radio will need to be removed and sent out to a radio repair shop to correct this condition.
my gear lever is stuck in park and the car says it in drive
My car's shifter is in the "Park" position, but the indicator on the dashboard says the car is in "Reverse." Because the car is not in Park or Neutral it will not start. I have already tried re-setting the ignition switch, but no luck
I have a vibration when in drive while holding the car still at a stop light
This vehicle has a thermostat that fails in the open position which causes the temp gauge to drop below normal and heater to fail. The thermostat is located on the driver's side of the engine behind the alternator. You might need to remove the wheel to access the mounting bolts. You will need multiple rachet extensions and some patience. Dealer wants $500 to replace thermostat. Do it yourself for less than $100.
