(b) Check the intermittent operation.

  1. Connect the positive (+) lead of a voltmeter to terminal A-3 (+1) and the negative (-) lead to terminal B-2 (EW).
  2. Connect the positive (+) lead of the battery to terminal A-2 (+B) and the negative (-) lead to terminal B-2 (EW) and A-1 (+S).
  3. Turn the wiper switch to the INT position.
  4. Connect the positive (+) lead of the battery to terminal A-1 (+S) for 5 seconds.
  5. Connect the negative (-) lead of the battery to terminal A-1 (+S). Operate the intermittent wiper relay and check the voltage between terminals A-3 (+1) and B-2 (EW).

    OK:

    Voltage changes as shown in the illustration.


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