Here's why:
* AC Condensation: Air conditioners remove moisture from the air. This moisture condenses on the evaporator coils inside the car's dashboard. This condensate is then drained away via a small drain tube or line.
* Clogged Drain Line: If this drain line becomes clogged (with debris, mold, or other gunk), the water can't drain properly. Instead, it backs up and overflows, often finding its way onto the passenger side floor (as this is often the lowest point in the system). The water may run down behind the dashboard and emerge near the blower motor area.
* Leak from Fan Motor/Condenser: Water leaking from the fan motor area is likely the *result* of the clogged drain, not the primary cause. The water is likely traveling along the path of least resistance and finding its way through the blower motor area or around the AC condenser. The fact that your AC isn't cold further supports this – a full condensate pan can prevent proper airflow and cooling.
In short: The primary issue is almost certainly a blocked AC drain line. The leak near the fan motor and the lack of cold air are symptoms of this blockage.
What you should do:
1. Locate the AC drain: This usually involves looking under the car's dashboard on the passenger side. It might be accessible by removing some trim pieces.
2. Clear the drain: Use a shop-vac, compressed air, or a long, thin, flexible tool (like a coat hanger) to clear the blockage in the drain line. You may need to remove some under-dash panels for proper access.
3. Inspect the drain line: Check for any cracks or damage to the line itself. A replacement might be necessary if it's damaged.
Important Note: If you're not comfortable working on your car's AC system, it's best to take it to a qualified mechanic. Improperly handling the AC system can lead to refrigerant leaks, which are harmful to the environment and can damage the system.
