Electrical heater for vehicle windshields and windows

A method for installing an electrical heater for defrosting vehicle windshields and windows in a vehicle having:

• a conventional DC electrical system, a fan cooperating with a heater core of the vehicle engine, and forced-air ducting for providing heat from the heater core driven by the fan through the ducting to the passenger compartment of the vehicle via at least one under-windshield vent in the vehicle dashboard directed to the underside of the vehicle windshield, the method comprising the steps of:
• a) providing an electrically driven heater element;
• b) providing heater circuit wiring and electrically connecting said wiring to said element to electrically drive said element to produce heat from said element, wherein said heater circuit wiring is adapted to only be electrically connected to the conventional DC electrical system of the vehicle,
• c) mounting said heater element only to the under-windshield vents of the vehicle to thereby direct airflow flowing over said heater element as forced by the fan through the ducting and out from the under-windshield vents only onto the underside of the windshield.
