Washer Fluid Switch Failure

Possible Causes are:

Turn ignition off. Disconnect the Washer Fluid Level Switch harness connector. Measure the resistance of the Washer Fluid Level Switch between Terminals No. 1 and 2. Does the resistance measure greater than 3000 ohms? If yes, replace the Washer Fluid Level Switch. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS. If no, go to next step.
Turn ignition off. Disconnect the Washer Fluid Level Switch harness connector. Measure the resistance between ground and the Washer Fluid Level Switch Ground circuit. Is the resistance more than 5 ohms? If yes, repair the Washer Fluid Level Switch Ground circuit for an open. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS. If no, go to next step.
Turn ignition off. Disconnect the Washer Fluid Level Switch harness connector. Disconnect the BCM C2 harness connector. Measure the resistance of the Washer Fluid Switch Sense circuit between the Switch connector and the BCM connector. Is the resistance less than 5 ohms? If yes, replace the Body Control Module. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS. If no, repair the Washer Fluid Level Switch Sense circuit for an open. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS.
