Detailed Product Information

This Global Parts HVAC blend door actuator is used to position internal HVAC doors that control air temperature, vent selection, and recirculated air intake. In select Buick LeSabre and Buick Park Avenue models, as well as Oldsmobile 88, LSS, Regency, and 98 applications, it supports climate control operation where the system relies on an actuator to move the blend or temperature valve. It also fits Pontiac Bonneville and several Cadillac applications listed below. If you are replacing a failed HVAC actuator on a Buick LeSabre, Oldsmobile 88, or Pontiac Bonneville, confirm the vehicle’s HVAC configuration before installation.
