2001 GMC Sierra 2500 Problems

Heating & Air Conditioning -- Verified

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.

Electrical & Lights -- Verified

A clicking noise may be noted from the turn signal flasher after the turn signals are switched off.  This is commonly cause by a faulty turn signal switch which will require replacement.

Drive Train -- Verified

The 4WD transfer case position sensor or the selector switch may fail causing the service 4WD message to be displayed.

Engine -- Verified

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.

Exhaust & Emissions -- Verified

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
