ABSTRACT OF THE DISCLOSURE A system for heating a volume of windshield cleaning fluid in a motor vehicle. The system comprises a long narrow heating tube positioned in a U-shaped configuration and connected between a cleaning fluid reservoir and a pair of nozzles that spray the cleaning fluid on the windshield. A plurality of elongated nickel strips within the heating tube heat the cleaning fluid held in the U-shaped section when power is supplied to the nickel strips. A control circuit that includes a timer circuit, an engine speed sensor, a pulse stretcher, a heater turn-on circuit and a temperature sensor, controls the power supplied to the nickel strips. The engine speed sensor shuts down the system if the engine is not running and functions by sensing the AC signal component that is superimposed on the vehicle DC power supply when the engine is running. In an alternative embodiment, the U-shaped heating tube is replaced by a hollow aluminum vessel having an internal fluid chamber. Cleaning fluid is held in the fluid chamber and heated by a plurality of metal heating fins or pins that extend into the fluid chamber. The heating fins or pins are heated by a plurality of PTC thermistors positioned on the outside of the aluminum vessel. The heating process is controlled by a control circuit connected to the plurality of thermistors.
