Wiper Switch: Testing and Inspection

Wiper/Washer Switch Test:

CAUTION:
^ All SRS wire harnesses are covered with yellow insulation. Before you disconnect any part of an SRS wire harness, disconnect the airbag connectors.
^ Whenever the ignition switch is ON (II), or has been turned OFF for less than three minutes, be careful not to bump the SRS unit; the airbags could accidentally deploy and cause damage or injuries.
^ For additional precautions, refer to the Air Bags and Seat belts.

Wiper/Washer Switch Test:

1. Remove the steering column covers.
2. Disconnect the 8P connector from the switch.
3. Remove the two screws, then pull out the switch.
4. Check for continuity between the terminals in each switch position according to the table.
5. If all the tests prove OK, but the system does not work, check for continuity in the switch harness (between the main wire harness and the switch assembly).
