ABSTRACT OF THE DISCLOSURE An auxiliary power system for an air conditioner and heater of a vehicle includes an auxiliary motor which is selectively connected by an electromagnetic clutch of a jack shaft assembly to drive the compressor of the vehicle's air conditioner. The jack shaft as- sembly reduces the RPM of the auxiliary motor to an RPM suitable for operating the compressor. The auxiliary engine has a cooling system and an exhaust system which are respectively connected to the cooling and exhaust systems of the vehicle's main engine. A baffle plate is provided at the point of connection to direct the flow of exhaust gases from the auxiliary engine into the exhaust system of the main engine. Solenoid actuated valves circulate coolant fluid from either the auxiliary or main engine to selectively heat water in a tank or to heat the interior of the passenger compartment of the vehicle. An auxiliary fan cools the condenser and radiator of the vehicle when the auxiliary engine is operating. Shroud doors are closed to direct the flow of air from the auxiliary fan when the main engine is not operating and are opened to bypass the auxiliary fan when the main engine is operating. The operational RPM of the auxiliary engine is maintained by a vacuum- actuated bellows which is spring-biased to control the movement of the throttle of the engine's carburetor.
