WIPER / WASHER: WIPER SWITCH: INSPECTION
1. INSPECT WINDSHIELD WIPER SWITCH ASSEMBLY
(a) Check the windshield wiper switch.
(1) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
If the result is not as specified, replace the switch assembly.
(b) Check the front washer switch.
(1) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
If the result is not as specified, replace the switch assembly.
(c) Check the intermittent operation.
(1) Connect the voltmeter positive (+) lead to terminal E16-3 (+1) and the negative (-) lead to terminal E15-2 (EW).
(2) Connect the battery positive (+) lead to terminal E16-2 (+B) and the negative (-) lead to terminal E15-2 (EW) and E16-1 (+S).
(3) Turn the wiper switch to the INT position.
(4) Connect the battery positive (+) lead to terminal E16-1 (+S) for 5 seconds.
(5) Connect the battery negative (-) lead to terminal E16-1 (+S). Operate the intermittent wiper relay and check the voltage between terminals E16-3 (+1) and E15-2 (EW).
Standard Voltage:
Refer to the illustration below.
If the result is not as specified, replace the switch assembly.
