Front Wiper Switch Test

Disconnect negative battery cable. Unplug multifunction switch harness connector. See FRONT WIPER SWITCH under REMOVAL & INSTALLATION.
Check for continuity across specified terminals of multifunction switch connector. See Fig 1 . See appropriate WIPER SWITCH CONTINUITY table. If continuity is not as specified, replace multifunction switch as an assembly.
