MULTIFUNCTION Switch

Disconnect negative battery cable. Remove steering column covers. Disconnect multifunction switch harness connector. Remove combination flasher relay. Check continuity between specified terminals with switch in appropriate position. See MULTIFUNCTION SWITCH CONTINUITY TEST table. For dimmer resistance, see MULTIFUNCTION SWITCH DIMMER RESISTANCE (2001) or MULTIFUNCTION SWITCH DIMMER RESISTANCE (2002) tables. See Fig 1 . If continuity is not as specified, replace multifunction switch.
