Why does water leak into passenger compartment?

Water can leak into the passenger compartment due to various reasons, including faulty door seals, damaged window seals, or blocked drainage channels. Additionally, a malfunctioning sunroof or improperly installed windshields can also contribute to leaks. Over time, wear and tear on these components can allow water to seep in during rain or when washing the vehicle. Identifying and repairing the source of the leak is essential to prevent further damage and maintain a dry interior.
