Common Causes Of Ac Water Leaks
Blocked Drainage Tubestops water from leaving the car. This causes water to build up inside the AC system and leak into the car. Dirt and debris often block this tube.
Clogged Cabin Air Filterreduces airflow inside the car. This makes the AC freeze and then melt, causing water to drip inside the car. Changing the filter regularly helps avoid this.
Damaged Drain Pancan crack or rust, letting water leak inside. The pan collects water from the AC system. Fixing or replacing it stops the leak.
Low Refrigerant Levelsmake the AC coil freeze. When it melts, water drips inside the car. Checking and refilling refrigerant keeps the system working well.

Step-by-step Fixes
The drain tube can get clogged with dirt or leaves. Clear it using a thin wire or compressed air. This helps water flow outside the car and stops leaks inside.
The cabin air filter catches dust and dirt. A dirty filter blocks airflow and causes water buildup. Replace it every year or when dirty to keep air fresh and dry.
Check the drain pan under the AC unit for cracks or holes. Water collects here before leaving the car. Fix any damage with waterproof tape or replace the pan to avoid leaks.
