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 Blue-White wire. With switch on high, lamp should light at Blue-Red wire.
- With washer on, lamp should light at Blue-Yellow wire. If switch does not work as described, replace it.
