Low Wash Fluid Level Indicator
When the Ignition Switch is turned to "RUN," voltage is applied to the Windshield Washer Solvent Level Switch. If washer solvent level is low, and the Windshield Washer Solvent Level Switch is closed, ground is applied to the "LOW WASH FLUID" Indicator. Once the indicator has been turned "ON," it will stay "ON" until the windshield washer solvent container has been refilled and the Windshield Washer Solvent Level Switch is open and the Ignition Switch turned to "OFF" and back to "RUN."
