Grand Marquis V8-4.6L VIN V Flex Fuel (2006)
C6-C7
Normal Operation
The instrument cluster is hardwired to the low washer fluid switch through circuit 82 (PK/YE). The low washer fluid switch closes when the washer
fluid level is low, providing a ground to the instrument cluster through circuit 57 (BK) and turning on the LOW WASHER FLUID LEVEL message.
When the washer fluid is above the low level, the low washer fluid switch opens, removing the ground to the instrument cluster, and the LOW
WASHER FLUID LEVEL message turns off.
Possible Causes
-
circuit 57 (BK) open
-
circuit 82 (PK/YE) open, short to voltage, or short to ground
-
washer fluid reservoir
-
instrument cluster
