Diagnostic Procedure

*LOW WASHER FLUID INDICATOR NOT OPERATING PROPERLY

Test	Action
1	Turn the ignition off. Check the level of the washer fluid reservoir. Is the washer fluid reservoir full? Yes: Go To 2 No: Add washer fluid as necessary. Perform BODY VERIFICATION TEST - Ver 1 .
2	Did the low washer fluid indicator fail to turn on when the reservoir was low? Yes: Go To 3 No: Go To 7
3	Turn the ignition off then on. This will start the bulb test. Did the low washer indicator illuminate for 3 to 10 seconds? Yes: Go To 4 No: Replace the Instrument cluster. Perform BODY VERIFICATION TEST - Ver 1 .
4	Turn the ignition off. Disconnect the washer fluid level sensor harness connector. Measure the resistance between ground and the ground circuit. Is the resistance below 10.0 ohms? Yes: Go To 5 No: Repair the ground circuit for an open. Perform BODY VERIFICATION TEST - Ver 1 .
5	Turn the ignition off. Disconnect the washer fluid level sensor harness connector. Disconnect the Instrument Cluster 9C29 harness connector. Measure the resistance of the washer fluid switch sense circuit between the washer fluid level sensor connector and the Instrument Cluster 9C29 connector. Is the resistance below 5.0 ohms? Yes: Go To 6 No: Repair the washer fluid switch sense circuit for an open. Perform BODY VERIFICATION TEST - Ver 1 .
6	Turn the ignition off. Disconnect the washer fluid level sensor harness connector. Turn the ignition on. Connect a jumper wire between the washer fluid switch sense circuit and the ground circuit. With the DRB, select Body, Electro/Mech Cluster (MIC) then Inputs/Outputs and observe the washer fluid switch status. Does the DRB display Wash Fluid: Closed? Yes: Replace the washer fluid level sensor. Perform BODY VERIFICATION TEST - Ver 1 . No: Replace the Instrument Cluster Perform BODY VERIFICATION TEST - Ver 1 .
7	NOTE: Perform this test if the low washer fluid indicator is on all the time. Turn the ignition off. Disconnect the washer fluid level sensor harness connector. Turn the ignition on and wait one minute. Monitor the low washer fluid indicator. Did the low washer fluid indicator turn off? Yes: Replace the washer fluid level sensor. Perform BODY VERIFICATION TEST - Ver 1 . No: Go To 8
8	NOTE: Perform this test if the low washer fluid indicator is on all the time. Turn the ignition off. Disconnect the washer fluid level sensor harness connector. Disconnect the Instrument Cluster C2 harness connector. Measure the resistance between ground and the washer fluid switch sense circuit. Is the resistance below 5.0 ohms? Yes: Repair the washer fluid switch sense circuit for a short to ground. Perform BODY VERIFICATION TEST - Ver 1 . No: Replace the Instrument Cluster Perform BODY VERIFICATION TEST - Ver 1 .
