Why is the turn signal not working on Wuling Sunshine?

[Laila]

There are many possible reasons for the turn signal not working on a Wuling Sunshine, including circuit breaks, faulty flasher relays, excessive contact gap, and other factors. Below is an introduction to turn signal knowledge: 1. Introduction: Turn signals are important indicator lights that activate when a motor vehicle turns to alert surrounding vehicles and pedestrians. The turn signal bulb uses a xenon tube, controlled by a microcontroller circuit, with alternating left-right flashing for continuous operation. The turn signal employs a flasher to achieve blinking lights, mainly categorized into resistance wire type, capacitor type, and electronic type. 2. Structural Principle: The resistance wire type can be further divided into thermal wire type (electrothermal) and vane type (spring-action), while the electronic type includes hybrid (relay with contacts and electronic components) and fully electronic (no relay). For example, the spring-action flasher operates on the principle of thermal expansion and contraction, using current heating effects to cause sudden movement of the spring plate, thereby opening and closing contacts to achieve light blinking.
