WIPER SWITCH

INSPECTION

1. INSPECT WINDSHIELD WIPER SWITCH ASSEMBLY




a. Measure the resistance according to the value(s) in the table.







Standard resistance:

b. Intermittent Operation Check
1. Connect the voltmeter (+) terminal to terminal C11-7 (+1) of the connector and the voltmeter (-) terminal to terminal C11-2 (EW).
2. Connect the positive battery (+) lead to terminal C11-17 (+B) of the connector and the negative battery (-) lead to terminals C11-2 (EW) and C11-16 (+S).
3. Turn the wiper switch to the INT position.
4. Connect the positive battery (+) lead to terminal C11-16 (+S) of the connector for 5 seconds.




5. Connect the negative battery (-) lead to terminal C11-16 (+S) of the connector. Operate the intermittent wiper relay and measure the voltage between terminals C11-7 (+1) and C11-2 (EW).




c. Front Washer Operation Check
1. Turn the wiper switch to the OFF position.
2. Connect the positive battery (+) lead to terminal C11-17 (+B) of the connector, and the negative battery (-) to terminals C11-16 (+S) and C11-2 (EW).
3. Connect the voltmeter (+) terminal to terminal C11-7 (+1) of the connector and the voltmeter (-) terminal to terminal C11-2 (EW). Measure the voltage between terminals C11-7 (+1) and C11-2 (EW) when turning the washer switch ON and OFF respectively.

Standard: Refer to the illustration.
