2003 GMC Sierra 1500 Problems

Service 4WD Message May be Displayed

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.

Improper HVAC Temperature and/or Air Delivery Due to Failed Mode Door Actuator

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.

Erratic Fuel Gauge Operation

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.

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.
