Washer Fluid Level Switch: Description and Operation
SYSTEM OPERATION
Washer Fluid Level Sensor
The standard washer fluid level sensor is mounted on the back side of the washer reservoir. A barbed nipple on the sensor is press-fit into a rubber
grommet seal installed in a hole in the back of the reservoir.
When the fluid level in the reservoir falls below the pivoting float on the sensor the float changes position and closes the internal switch contacts of
the sensor. Refer to Instrument Panel, Gauges and Warning Indicators/Instrument Panel Systems for diagnosis of the low washer fluid warning
lamp and circuit, including the sensor.
The washer fluid level sensor cannot be repaired. If faulty or damaged, the sensor unit must be replaced.
