2003 Chevrolet Silverado 2500 HD Problems

Heating and AC Temperature and Air Delivery Mode Door Actuators May Fail

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

Fuel Level Sensor Failure

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

Speedometer or Other Instrument Panel Gauge May Work Erratically

The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.

Dealers will cut the guide loop, remove a portion of the loop, and the remaining sides should be folded over and secured with a retainer. The recall began July 21, 2005. The GM recall number is 05037.

I would not buy another. In 12 years I have spent over 7000.00 in repairs and most of them I did myself. The transmission was done by others. Very poorly built truck. Everything is rusting out including brake lines and fuel lines. Only good side is the ride.

The truck clanks now I think its the throw out bearing and it leaks small amounts of oil not sure from where and the transfer case leaks tr...
