Wiper Switch: Testing and Inspection

WIPER AND WASHER: WIPER SWITCH:

INSPECTION

1. INSPECT WINDSHIELD WIPER SWITCH ASSEMBLY





(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:
Front Wiper Switch





Front Washer Switch





(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.
