Wiper Switch: Testing and Inspection
Front Wiper/Washer Switch
Right Multi-Function Switch Test
Be certain to perform the diagnosis for the front wiper system and/or front washer system before testing the right multi-function switch. The wiring
information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out
information and location views for the various wire harness connectors, splices and grounds.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING
WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND
ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM
CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE
WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN
ACCIDENTAL AIR- BAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
1. Disconnect and isolate the battery negative cable.
2. Remove the right multi-function switch from the steering column and disconnect the cross body wire harness connector for the switch from the
switch connector receptacle.

3. Using an ohmmeter, check the right multi-function switch continuity at the switch terminals.
4. If the switch fails any of the continuity checks, replace the faulty right multi-function switch. If the switch is OK, repair the open or shorted front
wiper and washer system circuits between the right multi- function switch and the front wiper motor or the front washer pump/motor as required.
