Washer Fluid Level Switch: Description and Operation

SYSTEM OPERATION
The washer fluid level sensor is mounted near the bottom of the rearward facing side of the washer reservoir. A barbed nipple on the sensor is press-fit into a rubber grommet seal installed in the mounting hole on the reservoir.

When the fluid level in the washer reservoir falls below the travel limit of the float, the internal switch contacts of the sensor close. Refer to Low Washer Fluid Warning Lamp in the Diagnosis and Testing of 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.
