1. Faulty Rain Sensor: The rain sensor, located on the windshield, detects the amount of rainfall and automatically turns on the wipers. However, if the rain sensor is faulty or dirty, it may malfunction and trigger the hazard lights.
2. Electrical Short: A short circuit in the electrical system, caused by moisture or water ingress, can also cause the hazard lights to turn on. Check for any damaged or exposed wires under the hood or near the rain sensor.
3. Faulty Hazard Switch: The hazard switch itself may be faulty, causing it to engage involuntarily. Try switching the hazard lights on and off manually to see if the problem persists.
4. Communication Error: If the hazard lights are integrated into the car's electronic control system, a communication error between different modules could also lead to the lights being turned on.
To resolve the issue, it's recommended to seek assistance from a qualified mechanic or an authorized Mercedes-Benz service center. They can properly diagnose the cause of the problem and perform necessary repairs to ensure that the hazard lights function correctly.
