Warning. The models described in this manual are equipped with an airbag system. Before working in the immediate vicinity of impact sensors, the steering column, or the right dashboard, disconnect the negative battery cable, then the positive battery cable, and wait at least 3 minutes. Accidental deployment of the airbag could cause injury (see paragraph 28).
Examination
1. The multi-function switch is installed on the top of the steering column. The left switch turns on the direction indicator circuits, hazard warning lights, and also switches the headlights. The right switch turns on the windshield wipers and washers. In models produced before 1997, both switches are combined into one block. On 1993 and 1994 models, the airbag coil spring can be removed from the switch assembly. In models produced in 1995 and 1996, the coil spring is part of the switch block and can only be replaced together with the switches. In models produced since 1998, the switches are made in the form of two blocks and can be replaced separately from each other.
2. On models produced before 1997, remove the lower section of the steering column trim and disconnect the 6-pin and 12-pin connectors located at the base of the steering column. Further testing is performed on these connectors. On models produced since 1998, remove each switch being tested.
3. Using an ohmmeter or test lamp and the appropriate wiring diagram, check for contact between the switch terminals in each position (figure 7.3, a-c). If there is no contact between the terminals, replace the switch.
Replacement

6. For 1993-1994 models, apply two strips of tape across the airbag coil spring and outer housing (for fixing springs). Remove the three screws securing the coil spring to the switch. Disconnect the wiring connector and ground wire, then remove the coil spring.
7. On models made from 1995 to 1997, the coil spring is part of the switch, so DO NOT attempt to remove the coil spring from the switch. The new switch has the coil spring installed in the middle position.
8. Remove the switch mounting screws, disconnect the wiring connectors, then remove the switch from the steering column (figure 7.8).
