mikeyp... From the manual Whistle

Quote:
HEADLAMP POWER WASH
If the headlamps are on, and there is sufficient liquid in the washer reservoir, operating the screen washer will also power-wash the headlamps.
The headlamp power wash will operate on every fifth operation of the screen washer, provided that the headlamps are still switched on and 10 minutes have elapsed since the last headlamp wash.
Switching the headlamps off and back on again will reset the cycle.
If the vehicle is fitted with the Terrain Response system, the headlamp wash will operate every third operation of the screen washer in all Special Programs (see Terrain Response, 210).
Note: In the screen washer reservoir, if the fluid level sensor detects a low level, the headlamp power wash is inhibited. Heated washer jets
If the ambient temperature falls to a point where icing of the washer jets could occur, power is applied to heat the jets provided that the starter switch is in position ’II’.
An approved screenwash is necessary to prevent freezing in very cold weather, see LUBRICANTS AND FLUIDS, 329.


The plot is getting sinister now. In the manual I downloaded from the LR web site just at the end of 2009, and as per the printed manual I got with the car, heres all it has to say on the matter on Page 109 (as per the Index under Headlamp Washers):

"HEADLAMP WASHERS
If the headlamps are on, operating the screen washer will also power wash the headlamps.
Note: If the fluid level sensor detects a low level, the headlamp power wash is inhibited."


How old is your manual?

The dealer is only interested is selling cars. He doesn’t care how the work.

Thank you so much Pete, I never thought the fuse was in that place and not with those behind the glove box. Rolling Eyes
