HEADLAMP WASHERS - EXPORT (Continued)

OPERATION

The headlamp washer system utilizes a separate
high pressure pump that is attached to the wind-
shield washer reservoir. The headlamp washer pump
feeds four nozzles that are mounted behind the front
fascia of the vehicle. The nozzle bodies have a tele-
scopic action that will extend the nozzles in front of
the headlamp assembly. During the telescopic action,
doors in the fascia will open to allow the nozzles to
advance into the proper spray position. These nozzles
spray the headlamps when the system is activated.
