(b) Check the intermittent operation.
(1) Connect a voltmeter positive (+) lead to terminal D40-3 (+1) and a negative (-) lead to terminal D39-2 (EW).
(2) Connect a battery positive (+) lead to terminal D40-2 (+B) and a negative (-) lead to terminal D39-2 (EW) and D40-1 (+S).
(3) Turn the wiper switch to the INT position.
(4) Connect a battery positive (+) lead to terminal D40-1 (+S) for 5 seconds.
(5) Connect a battery negative (-) lead to terminal D40-1 (+S). Operate the intermittent wiper relay and check the voltage between terminals D40-3 (+1) and D39-2 (EW).
OK:
Voltage changes as shown in the illustration.
If the result is not as specified, replace the windshield wiper switch assembly.
