Fig.19 Washer Pump Fluid Flow
Washer fluid is gravity-fed from the washer reservoir to the inlet port of the washer pump housing. An integral shuttle valve is located in a housing
on the outlet port side of the pump housing. This shuttle valve controls which washer system plumbing receives the washer fluid being pressurized
by the pump. When the pump impeller rotates in the counterclockwise direction (viewed from the bottom), pressurized washer fluid is pushed out
the front washer system port and biases the shuttle valve to the left, sealing off the rear washer system outlet nipple. When the pump impeller
rotates in the clockwise direction (viewed from the bottom), pressurized washer fluid is pushed out the rear washer system port and biases the
shuttle valve to the right, sealing off the front washer system outlet nipple.
The washer pump/motor unit can be diagnosed using conventional diagnostic tools and methods.
