Washer Fluid Level Switch: Description and Operation

The washer fluid level sensor is mounted near the front of the washer reservoir, above the two washer pumps. A barbed nipple on the sensor is press-fit into a rubber grommet seal installed in a hole in the front 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 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.
