WASHER SWITCH

Description

INFOID:0000000006247908

• Washer switch is integrated with combination switch (wiper and washer switch).

• Combination switch (wiper and washer switch) switches polarity between front washer operating and rear

washer operating to supply power and ground to the front and rear washer motor.

Component Inspection

INFOID:0000000006247909

1.

 CHECK FRONT WASHER SWITCH

1. Turn the ignition switch OFF.

2. Disconnect combination switch (wiper and washer switch).

3. Check continuity between the combination switch (wiper and

washer switch) terminals.

Does continuity exist?

YES

>> GO TO 2

NO

>> Replace combination switch (wiper and washer switch). Refer to 

WW-70, "Removal and Installa-

tion"

.

2.
