To complete the work you will need a multimeter.
Removal the steering column switches
1. Prepare the vehicle for work and disconnect the wire terminal from the negative terminal of the battery (see "Preparing the car for maintenance and repair").
2. Remove the decorative steering column trims (see "Decorative steering column trims - removal and installation").
3. By squeezing the spring clips of the right switch, we remove it from the connector together with the connected wiring harness block.
4. Disconnect the wiring harness connector from the switch.
Position of the steering column shift levers:
A - left steering column switch (headlight and turn signal switch);
B - right steering column switch (windshield wiper and washer switch).
Note: The dotted lines indicate positions in which the switch levers are not locked. The right switch lever has two buttons for controlling the trip computer.

* Terminal designations are printed on the switch body.
** Non-fixed position.
*** Installed on some vehicles.
5. Disconnect the wiring harness block of the trip computer control buttons.
6. Remove the left steering column switch in the same way.
Examination
Using a multimeter in ohmmeter mode, we check the closure of contacts in the switches at different positions of the switch lever.
Note: The order of contact closure for different positions of the switch levers is presented in Table 13.9.1.
Installing steering column switches
We install the switches in reverse order.
Removal the connector
1. Remove the decorative steering column trims (see "Decorative steering column trims - removal and installation").
2. Remove the steering wheel (see "Steering wheel - removal and installation").
3. Remove the steering column switches (see above).
4. On vehicles with a driver's airbag, disconnect the wiring block from the contact ring.
Note: The connector can be removed together with the contact ring. If necessary, unscrew the four screws and remove the contact ring from the steering shaft.
Warning! When removing the steering wheel, the movable part of the contact ring is fixed by a locking mechanism, which prevents it from rotating. Do not press on the retainer ring or rotate the movable part of the contact ring. As a result, the central position of the movable part of the ring may be disturbed during assembly. In this case, there is a high probability of damage to the contact ring when turning the steering wheel to one of the extreme positions.
5. Disconnect the horn switch wiring harness.
6. Using an 8 mm socket wrench, loosen the bolt securing the steering column switch connector and remove the connector from the steering column.
Installing the connector
1. Install the connector on the steering column.
2. Lightly tighten the connector mounting bolt (so that the switch position can be changed by hand).
Note: It is necessary to install the steering column switch connector in such a position that the central screw for fastening the lower steering column trim can be screwed into the corresponding hole in the connector.
3. Install the lower steering column trim in place and use a Phillips screwdriver to tighten the two screws securing the trim to the instrument panel crossbar.
4. Adjust the position of the connector on the steering column, achieving the ability to screw the central screw for fastening the steering column trim into the corresponding hole in the connector.
5. Having found the optimal position of the connector, unscrew the two screws and remove the lower steering column cover.
6. Without moving the connector, tighten its mounting bolt.
7. We carry out further work in the reverse order of removal.
