How to Unclog a Blocked Car Air Conditioning Drain Pipe?

[KingLee]

Use a Phillips screwdriver to remove the front panel and partition, exposing the condenser and drain tray. Fill a plastic water bottle with water and flush the drain pipe along the tray several times to see if it can be unclogged. If that doesn't work, use thin iron wire to slowly unclog and remove the blockage, then flush with water until the drainage is smooth. Reinstall the partition in the reverse order of removal.
