Take back control of cabin temperature with the SKP HVAC Blend Door Actuator, part number SK604101. This heater blend door actuator opens and closes the blend door inside your vehicle's HVAC system to regulate air temperature. It fits many vehicles, among them the 1999-2002 Chevrolet Silverado 1500, 1999-2002 Chevrolet Silverado 2500 and 1999-2002 GMC Sierra 1500. It is a direct-fit replacement for the listed applications and is cataloged for the main / lower main position. See the Buyer's Guide tab for the full list of vehicles.
The blend door actuator sets the position of the door that controls how air is split between the heating and cooling paths of the HVAC system. Signs it may need replacing include a clicking or ticking noise from behind the dash, air that stays hot or cold no matter where the temperature control is set, or a temperature setting that does not respond. Because these symptoms can also come from controls or wiring, diagnose the cause first. If a failed actuator is the cause, SKP SK604101 replaces it.
What does a blend door actuator do?
It opens and closes the blend door in the HVAC system, setting how much air passes through the heater side versus the cooled side so the cabin reaches the temperature you select.
