Wiper/Washer Switch
- Unplug the 2 wiper/washer connectors at base of steering column. Connect one probe of a self-powered test lamp (or ohmmeter) to the Black wire in the 2-pin switch connector.
- With switch off, no continuity should be present between Black wire and any others. With switch on low, lamp should light at White wire. With switch on high, lamp should light at Red wire. With washer on, lamp should light at Blue wire.
- If switch does not work as described, replace it.
