WINDSHIELD WASHING:
Pulling the Windshield Wiper Switch rearward closes the “wash” contact providing a
switched ground input to the GM. The GM activates the windshield washer pump directly
via a power output final stage transistor.
HEADLIGHT WASHING:
When the headlights are on, the headlight
washer pump is activated with the first
activation of the windshield washer pump.
The GM recognizes headlights on via K bus
signalling.
Within the same “on” cycle (ignition key has
not been switched off), it is only activated
again after five successive windshield washer
cycles.
The GM provides a ground on the headlight
washer relay control circuit providing pump
operation. The relay is located in the e-box.
The X5 uses three separate washer pumps
which are all easily accessible on the 5.3 liter
washer fluid reservoir located in the engine
compartment.
