2004 GMC Sierra 2500 HD ProblemsSpeedometer 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.
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.
The daytime running lights are prone to burning out. Our technicians tell us that the light sockets may show signs of heat damage but usually are OK. Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 2001-2003 models is #4114K (trade number).
