Front Wiper Switch Test

WARNING: This page is about a different car, the 1995 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

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.
