Land Rover Discovery: Headlamp Washers - Description

- Washer jet
- Telescopic arm
- Washer fluid supply hose
NOTE:
The headlamp washers will only operate if the vehicle headlamps are
on.
The front bumper is fitted with two headlamp washers. The headlamp
washers are located in the bumper, below the headlamp assembly. The
headlamp washer is located in an aperture at the front of the bumper and
secured with two self-tapping screws to a bracket molded into the bumper
structure.
The headlamp washers are telescopic units which extend forward from the
bumper under washer fluid pressure supplied by the headlamp washer
pump. When the pump pressure decreases the headlamp washer is
automatically retracted back into the housing. The outer end of the
headlamp washer is fitted with a trim which blends the headlamp washer
into the bumper when it is not operating. Each headlamp washer has a washer jet
which directs washer fluid under pressure onto the headlamp lens
when the headlamp washer is extended.
The headlamp washer pump is a bi-directional pump, Rotation of the pump
in one direction pumps washer fluid to the left headlamp washer jet, the
opposite direction pumps washer fluid to the right headlamp washer jet.
The change of pump rotation is controlled by the CJB changing the polarity
of the voltage supplied to the windshield washer pump motor via two relays
in the Engine Junction Box (EJB).
