We remove the steering column switches for repairs, as well as for removing the steering column
The steering column switch consists of a connector secured with a clamp to the steering gear shaft bracket, and two switches.
The left switch turns on the turn signals and headlights, and the right one controls the operation of the windshield washers and wipers.
The switches are secured in the connector with latches.
The positions of the switch levers are shown in Fig. 2, and the contacts closed in this case are given in the table.
The bold lines show the initial positions, the thin lines show the fixed positions, and the dotted lines show the non-fixed positions of the levers.
