1. Apparatus for providing a cleaning fluid to a vehicle surface comprising:
- a) an inlet port for receiving an amount of fluid;
b) a reservoir in fluid communication with the inlet port for storing fluid which enters a reservoir interior from the inlet port, said reservoir including an expandable portion that expands when fluid in the reservoir freezes to prevent damage to the reservoir;
c) an outlet port in fluid communication with the reservoir for dispensing an amount of fluid; and
d) a control circuit for controlling dispensing of the fluid from the outlet port.

Abstract
Apparatus and method for providing a heated cleaning fluid to a vehicle surface. The apparatus has an inlet port for receiving an amount of fluid; an outlet port for dispensing an amount of heated fluid; a heating element that heats up fluid passing from the inlet to the outlet; and a control circuit for energizing at least a portion of the heating element with a voltage to heat the fluid passing from the inlet to the outlet.

44. Apparatus for providing a heated cleaning fluid to a vehicle surface comprising:
-
an inlet port for receiving an amount of fluid; a heating element in contact with fluid as the fluid flows from the inlet port flows; an outlet port in fluid communication with the heating element for dispensing an amount of heated fluid; a temperature sensor coupled directly to the heating element; and a control circuit for energizing at least a portion of the heating element with a voltage to heat the heating element and the fluid passing from the inlet, in contact with the heating element, to the outlet, wherein the control circuit selectively energizes and de-energizes at least a portion of the heating element based on input from the temperature sensor to prevent the fluid from reaching a boiling point of the fluid.
