Wiper Switch: Testing and Inspection
INSPECTION1. INSPECT WINDSHIELD WIPER SWITCH ASSEMBLY
a. Measure the resistance according to the value(s) in the table.
b. Intermittent Operation Check
1. Connect the voltmeter (+) terminal to terminal C11-3 (+1) of the connector and the voltmeter (-) terminal to terminal C25-2 (EW).
2. Connect the positive battery (+) lead to terminal C11-2 (+B) of the connector and the negative battery (-) lead to terminals C25-2 (EW) and C11-1 (+S).
3. Turn the wiper switch to the INT position.
4. Connect the positive battery (+) lead to terminal C11-1 (+S) of the connector for 5 seconds.
5. Connect the negative battery (-) lead to terminal C11-1 (+S) of the connector. Operate the intermittent wiper relay and measure the voltage between terminals C11-3 (+1) and C25- 2 (EW).
Standard: Refer to the illustration below.
c. Front Washer Operation Check
1. Turn the wiper switch to the OFF position.
2. Connect the positive battery (+) lead to terminal C11-2 (+B) of the connector, and the negative battery (-) to terminals C11-1 (+S) and C25-2 (EW).
3. Connect the voltmeter (+) terminal to terminal C11-3 (+1) of the connector and the voltmeter (-) terminal to terminal C25-2 (EW). Measure the voltage between terminals C11-3 (+1) and C25-2 (EW) when turning the washer switch ON and OFF respectively. Standard: Refer to the illustration.
