Wiper Switch: Testing and Inspection





WIPER / WASHER: WIPER SWITCH: INSPECTION

1. INSPECT WINDSHIELD WIPER SWITCH ASSEMBLY

(a) Check the front 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 (w/o Intermittent timing adjustment).

(1) Connect a voltmeter's positive (+) lead to terminal E14-3 (+1) and the negative (-) lead to terminal E13-2 (EW).

(2) Connect a battery positive (+) lead to terminal E14-2 (+B) and the negative (-) lead to terminals E13-2 (EW) and E14-1 (+S).

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

(4) Connect a battery positive (+) lead to terminal E14-1 (+S) for 5 seconds.

(5) Connect a battery negative (-) lead to terminal E14-1 (+S). Operate the intermittent wiper relay and check the voltage between terminals E14-3 (+1) and E13-2 (EW).

OK:

Voltage changes as shown in the illustration below.





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

(d) Check the intermittent operation (w/ Intermittent timing adjustment).

(1) Connect a voltmeter's positive (+) lead to terminal E14-3 (+1) and the negative (-) lead to terminal E13-2 (EW).

(2) Connect a battery positive (+) lead to terminal E14-2 (+B) and the negative (-) lead to terminals E13-2 (EW) and E14-1 (+S).

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

(4) Connect a battery positive (+) lead to terminal E14-1 (+S) for 5 seconds.

(5) Connect a battery negative (-) lead to terminal E14-1 (+S). Operate the intermittent wiper relay and check the voltage between terminals E14-3 (+1) and E13-2 (EW).

OK:

Voltage changes as shown in the illustration below.





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

(e) Check the front washer operation.

(1) Turn the wiper switch OFF.

(2) Connect a battery positive (+) lead to terminal E14-2 (+B) and a negative (-) lead to terminals E14-1 (+S) and E13-2 (EW).

(3) Connect a voltmeter's positive (+) lead to E14-3 (+1) and a negative (-) lead to terminal E13-2 (EW).

(4) Turn the washer switch ON and OFF, and check the voltage between terminals E14-3 (+1) and E13-2 (EW).

OK:

Voltage changes as shown in the illustration below.





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

(f) Check the rear 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.

(g) Check the rear 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.
