ABSTRACT:
In an air conditioner control system for vehicles, a first control signal generator is responsive to a first switch to energize an actuator to place the system in its inside air recirculation mode of operation, and a second control signal generator is responsive to a second switch to deenergize the actuator to place the system back into its outside air supply mode of operation. A third control signal generator is responsive to a third switch whereby when the output value of an outside air sensor exceeds a given value within a given time period, the actuator is energized for a given time interval to place the system in the inside air recirculation mode and after the expiration of the given time interval the actuator is deenergized to place the system back in the outside air supply mode.
