Sensor-Washer Fluid Level: Description
The washer fluid level switch is a single pole, single throw reed-type switch mounted on the left outboard side of the washer reservoir (5), just rearward of the washer pump/motor. Only the molded plastic switch mounting flange (2) and the integral connector receptacle (1) are visible when the switch is installed in the reservoir. A short nipple formation (3) extends from the inner surface of the switch mounting flange, and a barb on the nipple is pressed through a rubber grommet seal (6) installed in the mounting hole of the reservoir.
A small, molded plastic float (4) has two pivot pins (7) near its center that are snapped into two receptacles near the ends of two stanchions that extend toward the float from the nipple formation. 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. If ineffective or damaged, it must be replaced.
