2004 GMC Sierra 1500 Problems
The 4WD transfer case encoder motor position sensor or the selector switch may fail causing the service 4WD message to be displayed. Fault code(s) stored in the transfer case control module will be of assistance in determining the exact fault causing the message to be displayed.
One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.
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.

2004 GMC Sierra 1500 Recalls
The retainer clip for the fuel rail pulse damper may fracture and allow the damper to come loose from the fuel rail. A fuel leak in the presence of an ignition source may result in a fire. Dealers will replace the engine fuel rail pulse damper free of charge. The recall began August 31, 2006. The GM recall number is 06080.
The second row center seat belt routing may make it difficult to position correctly on smaller passengers. If the seat belt rides up to fit around the abdomen, the risk of internal injury is increased in a crash. 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.
