Washer Fluid Level Switch: Description and Operation
Description
DESCRIPTION
The washer fluid level switch is a single pole, single throw reed-type switch mounted just above the sump area near the bottom of the washer reservoir.
Only the molded plastic switch mounting flange and the integral connector receptacle are visible when the switch is installed in the reservoir. A short
nipple formation extends from the inner surface of the switch mounting flange, and a barb on the nipple near the switch mounting flange is pressed
through a rubber grommet seal installed in the mounting hole of the reservoir.
A molded plastic float rides saddle-like over a molded plastic beam that extends axially from the switch mounting flange. A small permanent magnet is
secured in a receptacle on the top of the float, and the reed switch is concealed within the beam. 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.
