Headlamp Washer Spray Nozzle: Description and Operation
Headlamp Washer Nozzle - Operation
HEADLAMP
When the headlamp washer pump/motor unit is activated, pressure builds within the high pressure hoses to each headlamp washer nozzle. Driven by this
pressure, a control valve integral to each nozzle allows a precisely metered quantity of washer fluid to be sprayed in several high pressure streams against
the lenses of both front lamp units. When the pressure drops, the control valve closes and the nozzle spray ceases.
The headlamp washer system only operates when the engine is running and the headlamps are turned ON. When those conditions have been met, the
headlamp washer system operates whenever the front (windshield) washer system is activated.
