ACDelco 15-71937 GM OE Temperature Mode Valve Actuator Assembly

The ACDelco 15-71937 is a GM Original Equipment Temperature Mode Valve Actuator Assembly designed to restore proper HVAC function on compatible GM vehicles. This pneumatic servo mounts directly on the HVAC housing and controls the movement of HVAC doors or valves that regulate airflow temperature and mode selection inside the cabin.

As a vacuum-operated actuator, it receives signals from the HVAC controller to precisely move and position the internal doors or valves. A failed or leaking vacuum actuator can result in loss of temperature control, stuck airflow modes, or reduced climate control performance — this direct OEM replacement restores full functionality.
