- Blocked sunroof drains: If the sunroof drains are clogged or blocked, rainwater can accumulate and overflow into the footwell area.
- Leaking windshield: A leak around the windshield can allow water to seep into the car and collect in the footwell.
- Damaged door seal: A torn or damaged door seal can let water enter the car when it rains or when you wash it.
- Leaking heater core: A faulty or leaking heater core inside the dashboard can cause coolant to leak into the footwell. This is usually accompanied by a sweet odor.
- Blocked cowl drains: The cowl drains located at the base of the windshield can get blocked by leaves and debris, causing rainwater to overflow and enter the footwell.
- Air conditioning drain tube: If the air conditioning drain tube is blocked or kinked, condensation from the air conditioner can build up and drip into the footwell.
- Defective weather stripping: Deteriorated or damaged weather stripping around doors, windows, or the sunroof can allow water to seep in.
To identify the exact source of the water leak in your Mercedes, it's recommended to have the car inspected by a professional mechanic or an authorized Mercedes-Benz service center. They will be able to properly diagnose and fix the issue to prevent further damage and ensure the comfort and safety of your vehicle.
