Possible Causes:

Damaged Rubber Seals: Worn o r cracked rubber seals around the windows can allow water to seep into the door panel.
Clogged Drain Holes: If the drain holes at the bottom of the door are clogged, water may accumulate and leak inside the car.
Loose Regulator Fittings: If the regulator assembly is not properly sealed, it can allow water to enter.

Solutions:

Inspect and Replace Seals: Regularly check the rubber seals around the windows and replace them if they are damaged o r worn.
Clear Drain Holes: Ensure the drain holes are clear of debris to allow water to escape properly.
Professional Sealing: If the issue persists, visit a professional mechanic to inspect and reseal the window components.
