Swap out a malfunctioning original climate control module with the Dorman OE Solutions 599-009, a remanufactured Dorman HVAC control module that is function tested to operate like the stock unit. It fits many Chevrolet, GMC and Cadillac trucks and SUVs, among them the 2003-2004 Chevrolet Silverado 1500, 2003-2004 Chevrolet Silverado 2500 and 2003-2004 GMC Sierra 1500. See the "Vehicles it fits" section for the full list and engine details.
Have the climate controls stopped working? If a failed module is the cause, this unit replaces it. Diagnose the problem first, because wiring, fuses and other HVAC components can produce similar symptoms. Signs this module may need replacing include controls that stop responding altogether, buttons or knobs that no longer change fan speed, temperature or airflow mode, and settings that work only intermittently.
- Direct replacement: designed to look and work like the original module on the listed vehicles.
- Function tested: the module is tested to confirm it operates the same as the stock unit.
- Simple installation: no advanced vehicle knowledge is needed to install it properly.
- Quality backing: supported by a team of engineers and inspectors in the United States.
Position: front and rear.
