<p>A system and method for maintaining a washer fluid above a predetermined temperature at a point of delivery where the fluid is directed onto a windshield of a vehicle. The system and method include a washer nozzle (26) that has an internal resistance such that, when a current is passed through the nozzle, a temperature of nozzle is maintained at a predetermined temperature which is above the freezing temperature of the fluid. In one embodiment, the nozzle body (28) and its electrical terminals (36, 38) are an one-piece molded construction, with another embodiment having a plurality of metallic conductors (40, 42) insert-molded into the nozzle. The nozzle (26) has a nozzle body (28) which is molded of an electrically conductive, internally-resistive, thermo-plastic which can be energized with less than about twenty or even ten amperes so that the nozzle body temperature is maintained.</p> |
