2003 Chevrolet Silverado 2500 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.

Stalling or Low Engine Idle Speed Due to Dirty Throttle Body

A dirty throttle body may cause a lower than normal idle and possible stalling condition. Performing a throttle body service will commonly correct this concern.
