OE Supplier Turn Signal Switch; With Dimmer and OnBoard Computer Function | 61318363668

The turn signal on your BMW has a stand alone or combination switch connected to the steering column that is used to turn on your turn signals. It is connected behind the steering wheel with an extended stalk so it can be used with your fingers without removing your hands from the steering wheel. When lifted up it turns on the right turn signals and when pushed down it turns on the left turn signals in left hand drive vehicles. Most turn signals have an auto cancel function that turns the turn signal off after completing a major turn and returning the steering wheel to the straight forward position.

Some turn signal combination switches will also include the switches for headlights and hazard lights. Furthermore, some turn signal combination switches are complete switch assemblies mounted behind the steering wheel to control turn signals, headlights, hazard lights, windshield wipers, and cruise control with stalks on either side of the steering wheel.

Turn signal switches fail when the hinges for the stalk no longer hold the stalk up or disconnect from the switch. They can also fail with internal electrical circuit malfunctions leaving the turn signals and other systems controlled by the switch to be inoperable.

Replacing Your BMW Turn Signal Switch
Replacement of the turn signal switch requires removal of the steering column cover to access the turn signal switch mounting. Some turn signal switch assemblies contain the ring contact for the steering wheel horn and will require removal of the steering wheel to be replaced.
