Washer Fluid Level Indicator: Description and Operation
CIRCUIT OPERATION
Circuit G29 connects the low washer fluid switch to the warning lamp in the instrument cluster. Circuit F14 supplies battery voltage to the lamp.
When the low washer fluid switch CLOSES, it connects circuits G29 and Z1. Circuit Z1 provides a ground path, illuminating the warning lamp.
Circuit Z1 also provides ground for the windshield washer pump motor.
The low washer fluid warning lamp is located in the instrument cluster. Circuit G29 connects the warning lamp to the low washer fluid sensor in
the washer fluid reservoir. The switch in the sensor CLOSES when the fluid level drops below a calibrated level. When the switch CLOSES,
voltage flows through the warning lamp to ground on circuit Z1.
