2004 Chevrolet Trailblazer Problems
RepairPal has identified the most common problems with the 2004 Chevrolet Trailblazer based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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.
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»
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
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.
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 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.
Our technicians highly recommend that the transmission is serviced every 30,000 miles to avoid problems and maintain optimal operating order.
