    See this A/C Heater Blend Door Actuator
    For your 1999 Oldsmobile Cutlass 3.1L SFI OHV 6cyl

    The blend door actuator is a servo responsible for controlling the mix of warm air from the heater core and cool air from the A/C and outside. If it malfunctions, your climate control system may not respond properly when you change the temperature on the climate control system.
