ABSTRACT OF THE DISCLOSURE A vehicle preheating system which provides for the preheat- ing of the vehicle interior, as well as other components, is disclosed. The system includes an electrical heating element installed within the heater assembly of the vehicle and is sup- plied with electrical power by an external source. The standard vehicle heater fan is supplied with electrical power from a transformer and rectifier in the circuit, thus using only exter- nal power rather than vehicle battery power. The system is controlled by a timer controller,which may be preset to activate the heater assembly at some predetermined time prior to vehicle operation, and may provide for other component preheating devices such as engine and battery warmers. The timer controller may activate each of these devices simultaneously, or independently at various times depending upon the lead time required to thor- oughly warm each component. Alternatively, power may be applied to each device in turn in order to avoid excessive current draw from the external circuit. The timer controller may also contain additional circuitry interconnected with the vehicle ignition system which provides a visual and/or aural warning when the ignition system is activated and the system is still plugged in and receiving power from the external source. Alternatively, the timer controller may be set to deactivate the vehicle starter system when the timer controller is receiving external power. The external power cord is contained on a reel which is installed within the vehicle body and is retracted onto the reel for stor- age when not in use.
