Switch, Washer Fluid Level: Description
The washer fluid level switch (3) is a two-pin conductivity sensor with no moving parts. On vehicles with a gasoline engine, the switch is mounted on the rearward facing side of the washer reservoir on the front of the Front End Module (FEM) carrier, just to the left of the cooling module. On vehicles with a diesel engine, the washer fluid level switch is located in a dedicated hole on the lower, forward facing surface of the washer reservoir on the back of the left vertical post of the left fender support hydroform just outboard of the FEM carrier. 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 (1) extends from the inner surface of the switch mounting flange, and a barb on the nipple is pressed through a rubber grommet seal installed in the mounting hole of the reservoir. Two over-molded pins or electrodes (2) extend from the back of the nipple formation. The switch is connected to the vehicle electrical system through a dedicated take out and connector of the FEM wire harness.
The washer fluid level switch cannot be adjusted or repaired. If ineffective or damaged, the switch must be replaced.
