We remove the steering column switches for repair, as well as for removing the steering column.
The steering column switch consists of a connector fixed with a clamp on the steering shaft bracket and two switches
The left switch turns on the turn indicators and headlights, while the right switch controls the washer and windshield wipers.
Scheme for switching on direction indicators and alarms: 1 - direction indicator lamps in headlights: 2 - ignition switch; 3 - turn signal switch; 4 - side direction indicators; 5 - turn signal lamps in the rear lights; 6 - alarm switch; 7 - instrument cluster with control lamps for direction indicators and alarms; 8 - mounting block; K3 - relay-breaker for direction indicators and alarm; A - to power supplies
The switches are clipped into the connector.
Switch lever positions are shown in fig. 2, and the contacts closed in this case are given in the table.
Bold lines show initial positions, thin lines show fixed positions, and dotted lines show non-fixed positions of the levers.
