Reasons for car air conditioning water leakage into the interior: 1. Drain pipe obstruction: Long-term use of the drain pipe leads to aging, loosening, or bending, forming a wave-like shape that causes poor drainage and local blockages. 2. Drain outlet blockage: The drain outlet leading outside is blocked by debris, preventing condensation water from draining and gradually causing water to flow back. 3. Improper unit installation: Excessive tilt of the indoor unit or the pipe opening being too high prevents water from flowing. Here are additional details: Solutions: When water leakage occurs from the indoor unit, you can perform a self-check based on the above situations. If you can handle it yourself, that's better; if not, promptly seek professional technical assistance for on-site resolution.
