Washer Fluid Level Switch: Description and Operation
Description
DESCRIPTION
The washer fluid level switch (1) is a single pole, single throw reed-type switch mounted on the outboard facing side of the washer reservoir, just forward
of the washer pump. Only the molded plastic switch mounting flange and the integral connector receptacle (4) 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 is pressed through a rubber
grommet seal (2) installed in the mounting hole of the reservoir.
A small, molded plastic float (3) pivots on hinge stanchions that extend toward the float from the nipple formation. A small magnet 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, the switch must be replaced.
