Wiper Switch: Testing and Inspection

WIPER AND WASHER: WIPER SWITCH: INSPECTION

1. INSPECT WIPER SWITCH

(a) Check the resistance.

(1) Measure the resistance and check the results in accordance with the value(s) in the table below.

Standard:

Wiper Switch

If the result is not as specified, replace the windshield wiper switch assembly.

Standard:

Washer Switch

If the result is not as specified, replace the windshield wiper switch assembly.

(b) Check the intermittent operation.

(1) Connect the voltmeter positive terminal to terminal 3 (+1) of the E7 connector and the voltmeter negative terminal to terminal 2 (EW) of the E11 connector.

(2) Connect the battery positive (+) lead to terminal 2 (+B) of the E7 connector and the battery negative (-) lead to terminals 2 (EW) of the E11 connector and 1 (+S) of the E7 connector.

(3) Turn the wiper switch to the INT position.

(4) Connect the battery positive (+) lead to terminal 1 (+S) of the E7 connector for 5 seconds.

(5) Connect the battery negative lead to terminal 1 (+S) of the E7 connector. Operate the intermittent wiper relay and check the voltage between terminals 3 (+1) of the E7 connector and 2 (EW) of the E11 connector.

(1) Turn the wiper switch off.

(2) Connect the battery positive lead to terminal 2 (+B) of the E7 connector and the battery negative lead to terminals 1 (+S) of the E7 connector and 2 (EW) of the E11 connector.

(3) Connect the voltmeter positive terminal to terminal 3 (+1) of the E7 connector and the voltmeter negative terminal to terminal 2 (EW) of the E11 connector. Turn the washer switch on and off, and check the voltage between terminals 3 (+1) of the E7 connector and 2 (EW) of the E11 connector.
