Windshield Washer Pump: Description and Operation
To engage the windshield washer pump, push the knob at the end of the multi-function switch toward the steering column tube. When the multi-function
switch is in the OFF or INT position, the windshield wipers will run in LOW while the knob is pushed in. When the washer knob is released, the washer
will stop immediately, but the windshield wipers will continue to run for two or three sweeps, then return to their previously set mode. Washer
engagement does not affect windshield wiper operation when the multi-function switch is in the LOW or HIGH position.
