What is the reason for water leakage under the co-pilot's air conditioning filter in a car?

[DelLuna]

The reason for water leakage under the co-pilot's air conditioning filter in a car may be due to a blocked condensate drain outlet, causing backflow. The functions of the air conditioning filter include the following 3 points: 1. Provide fresh air: It prevents the car windows from fogging up, ensuring clear visibility for the driver and safe driving; it supplies fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety; it effectively sterilizes and deodorizes. 2. Ensure safety and hygiene: It keeps the cabin air clean and prevents bacterial growth; it effectively separates solid impurities such as dust, core powder, and grinding particles from the air; it intercepts pollen, ensuring that passengers do not experience allergic reactions that could affect driving safety. 3. Adsorb harmful substances: It adsorbs moisture, soot, ozone, and odors from the air, with strong and long-lasting moisture adsorption capabilities.
