        Component with harness connected

        (Windshield Wiper Switch Assembly)

        Connect a voltmeter positive (+) lead to terminal E16-3 (+1) and a negative (-) lead to terminal E15-4 (EW).

      2. Turn the wiper switch to the INT position.

      3. Operate the intermittent wiper relay and check the voltage between terminals E16-3 (+1) and E15-4 (EW).

        OK
        Voltage changes as shown in the illustration.

        w/o Intermittent Time Adjust Dial
        *1 Connect battery negative (-) lead to terminal E16-1 (+S)
        *2 11 to 14 V
        *3 Voltage between terminals E16-3 (+1) and E15-4 (EW)
        *4 3.3 +/- 1 second

        If the result is not as specified, replace the windshield wiper switch assembly.

    2. Check the front washer operation.

        (Windshield Wiper Switch Assembly)

        Connect a voltmeter positive (+) lead to terminal E15-7 (WF) and a negative (-) lead to terminal E15-4 (EW).

      2. Turn the power switch on (IG).

      3. Turn the washer switch on and off, and check the voltage between terminals E15-7 (WF) and E15-4 (EW).

        OK
        Voltage changes as shown in the following illustration.
