Why does the turn signal automatically reset?

[DelLeonardo]

It is designed so that when the driver intends to turn left and manually pushes the lever downward, upon completing the turning action and steering the wheel back to the right, the mechanism on the steering column triggers the fork, turning off the left turn signal to achieve the automatic reset effect. When you hear a 'click' sound while steering back, it means the turn signal lever has reset. If the turn signal does not reset automatically, it is likely due to a damaged positioning pin. Below is additional information: Turn Signal: The turn signal is the primary device indicating a vehicle's dynamic information, installed at the front and rear of the car. It is activated during turns to ensure driving safety. Proper use of turn signals allows other drivers to anticipate the vehicle's movements and make correct judgments. Turn Signal Bulb: The turn signal bulb uses a xenon tube with a microcontroller-controlled circuit, enabling continuous alternating flashing on both sides. The turn signal employs a flasher to achieve blinking lights, which can mainly be categorized into three types: resistance wire type, capacitor type, and electronic type.
