This small electric actuator drives the blend door inside the HVAC heater case, positioning it to control the mix of heated and cooled air that reaches the vents. When the original left-side unit strips its gears or loses position, temperature output can stick or swing from side to side — if a failed actuator is the cause, this replaces it.
Assembly contents: includes the lever arm, gear, cam gear hardware and linkage as applicable.
Quality internals: motor, drive gears, electronics and connections.
Validated: tested for function, durability and longevity.
OE-level fit: built to OE-level fit and function specifications.
