Faulty Door Ajar Sensor: One of the door ajar sensors may be faulty or malfunctioning. This can cause the light to stay on even when all doors are closed.
Loose Wiring: Check the wiring related to the door ajar sensors. Loose connections or damaged wires can also cause this issue.
Faulty Door Latch: If a door latch is not functioning properly, it may not trigger the sensor to register that the door is closed, causing the light to stay on.
Door Seal Issue: If the rubber door seal around any door is damaged or not sealing correctly, it may affect the sensor's ability to detect that the door is closed.
Electrical Issues: There may be a more general electrical problem, such as a short circuit, that is affecting the door ajar sensor light.
BCM (Body Control Module) Problem: In some cases, the Body Control Module (BCM), which controls various electrical functions in the vehicle, could be faulty and causing the door ajar sensor light to stay on.
To resolve this issue, it's recommended to visit a qualified mechanic or auto electrician who can properly diagnose the problem and repair or replace the faulty components.
