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

      2. Check the intermittent operation.


        1. Connect a voltmeter positive (+) lead to terminal L48-3 (+1) and a negative (-) lead to terminal L49-2 (EW).

        2. Connect a battery positive (+) lead to terminal L48-2 (+B) and a negative (-) lead to terminal L49-2 (EW) and L48-1 (+S).

        3. Turn the wiper switch to the INT position.

        4. Connect a battery positive (+) lead to terminal L48-1 (+S) for 5 seconds.

        5. Connect a battery negative (-) lead to terminal L48-1 (+S). Operate the intermittent wiper relay and check the voltage between terminals L48-3 (+1) and L49-2 (EW).

          OK
          Voltage changes as shown in the illustration.
