Is there a way to unclog the air conditioning plug in your car?

Question

The air conditioner is draining into the vehicle - 2005 Nissan Sentra

Answer 1

If you see cars on hot humid day, you can see them dripping water in the middle (bottom near the firewall) when the AC is running. You can see similar thing when window AC is running.

There's actually a drain pipe for this purpose. If the drain plug is blocked then the condensation can build up and leak into the car. You can jack up the car and get under it. Look for an open pipe / hose under the car. You can even try this with the AC running to build the water (some of it might leak through).

Then using wire coat hanger try to clean out the pipe. And you can even use a wet / dry vac to suck out any larger build up.

Good Luck.

Answer 2

You have to locate the drain coming out of the ductwork inside the car to the outside---usually in the engine compartment towards the center of the firewall that lines up with the lowest point of the ductwork inside the car or in the general area of the a/c evaporator. Or, it may come downwards from the duct. It should be a small hose sticking out that you'll need to unclog---try poking a wire or coat hanger into it.

Answer 3

There should be an outlet hose under the car. You need to look for the outlet and use a coat hanger or something to clear it out. The clog is almost always at the road end, so expect a bunch of dead leaves / dirt / etc. followed by a gush of backed up AC water.
