PINPOINT TEST F: THE WASHER FLUID LOW LEVEL WARNING IS INOPERATIVE

F1-F2:

F3-F6:

F6-F7:

Normal Operation
The instrument cluster is hardwired to the low washer fluid switch (part of the windshield washer reservoir) through circuit CMC20 (VT). The low washer fluid switch closes when the washer fluid level is approximately 1/3 full, providing a ground to the instrument cluster through circuit GD108 (BK/VT) and turning on the WASHER FLUID LOW LEVEL warning. When the washer fluid is above the low level, the low washer fluid switch opens, removing the ground to the instrument cluster, and the WASHER FLUID LOW LEVEL warning turns off.

Possible Causes
- Circuit GD108 (BK/VT) open
- Circuit CMC20 (VT) open or short to ground
- Washer fluid level switch (part of the windshield washer reservoir)
- Instrument cluster
