Continuity Test

Disconnect combination switch connectors. Check for continuity between specified terminals. See Fig 1. See appropriate WIPER/WASHER SWITCH CONTINUITY table. If there is no continuity, replace switch. If there is continuity, apply battery voltage across terminals B16 and B18. Check continuity between terminals B7 and B18. If there is continuity, switch is okay. If there is no continuity, replace switch.
