- Fuse Issue: A blown fuse could disable the power of certain components like gear shift lights.
- Damaged Shifter Assembly: If there is an internal issue or electrical wiring problem in the shifter assembly, it could cause the gear shift lights to stop functioning.
- Faulty Gear Indicator Switch: This switch plays a role in sending the gear position signal to the instrument cluster, but if it fails or has become disengaged the gear shift lights won’t work.
- Electrical Wiring Problems: Damaged or loose wiring in the gear shifter circuit can disrupt communication between the shifter, gear indicator switch, and the instrument cluster.
- Instrument Cluster Malfunction: In some cases, the problem could be with the instrument cluster itself; faulty or damaged circuit board or display panel can cause the lights to stop working.
