Sensor-Washer Fluid Level: Description
The washer fluid level switch is located on the left outboard side of the washer reservoir (5), near the windshield washer pump. The washer fluid level switch is a single pole, single throw reed-type switch. Only the molded plastic positioning flange (2) and the integral connector receptacle (1) are visible when the switch is installed in the reservoir. A seal flange with a large barbed nipple (3) on the switch housing passes through a rubber grommet (6) installed in the dedicated switch mounting hole of the washer reservoir.
A small, molded plastic float (4) with two pivot pins is attached to the stanchion (7) that extend toward the float from the nipple. A small magnet (8) is secured within the end of the float nearest the nipple and a reed switch is concealed within the nipple. A diagnostic resistor is connected between the two switch terminals within the switch mounting flange.
The washer fluid level switch cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
