Front Wiper Switch Test

NOTE: All terminals specified in this test are on wiper switch connector for vehicles with standard wipers. For vehicles with intermittent wipers, specified terminals are on switch side connector of intermittent module. Module is on lower instrument panel cover, near steering column.

Disconnect negative battery cable. Unplug multifunction switch harness connector. See FRONT WIPER SWITCH under REMOVAL & INSTALLATION. Using ohmmeter, check for continuity in wiper/washer terminals of multifunction switch with turned to listed wiper/washer positions. See Fig 1 . See WIPER SWITCH CONTINUITY . If continuity is not as specified, multifunction switch must be replaced as an assembly.
