Air conditioner condensation dripping into the floor.

I had the same problem. Drilled a hole in the round plastic extension beneath the glove box, behind the carpet. Now run a coat hanger through it, followed by alot of compressed air. It may take several times, debri from above may be continuosly replugging drain. when you are done, clean thoroughly, and patch with hot melt glue. Good luck.

SOURCE: Where do I find the air conditioner drain tube

the tube is located on the passenger side firewall you can see it from under the car where you will have to be when you clean it out with either blowing air into it or clean it out with a coat hanger. just becareful not to push to far inside so you don't poke a hole into the evaporator. Hope this helps leave a comment. By the way it is usually a little rubber tube hanging out of the fire wall.

The AC drain tube is located on the lower passenger side fire-wall, and it resembles a heater hose protruding out from the fire-wall about 2 inches (5 cm) and it will look like a small heater hose that is not connected to anything, and the AC drain is easily viewed from under the vehicle.

Use long pipe cleaners folded in half to clean out the AC drain, and be very careful that you do not damage the AC evaporator/core or the heater core.
