11. A method of providing a heated cleaning fluid to a vehicle surface comprising:

a) mounting a heater element in a heat exchanger and placing the heat exchanger into a fluid reservoir through an inlet port for receiving an amount of fluid;

b) coupling the reservoir to an outlet port in fluid communication with the reservoir for dispensing an amount of heated fluid;

d) heating fluid that passes from the inlet to the outlet port through said reservoir;

e) energizing the heater element with a voltage source to heat the heating element and the fluid passing from the inlet to the outlet through the reservoir; and

f) sensing the temperature of the heating element when voltage is applied to the heater element and de-energizing the heater element if the temperature is too high to prevent thermal runaway.
