-- locate the small diameter metal lines running horizontally and attached to the engine compartment firewall
-- locate the hole in the engine compartment firewall panel behind the small diameter metal brake lines
-- this hole leads to the drain opening in the air conditioner blower box mounted in the passenger compartment
-- follow the brake lines as they run from under the vehicle and turn toward the front wheel on the driver's side
-- locate the hole in the engine compartment panel behind the brake lines
-- insert a short length of stiff wire into the hole through the engine compartment panel to unblock the drain hole

    I actually found the hole but my problem is accessing it. I can stick the wire in the hole but can't get it inside the drain opening simply because I cannnot see it. I've tried a mirror only to discover it was too dark to see inside the hole. I can feel the drain with my finger, a bit of water even drip out. Is there no other way to access this?

    this is a good answer to the question. But its missing the final piece. The AC drain opening is NOT straight back! The AC drain hole opening is off center from the hole in the firewall and a couple of inches behind the opening. Aim your stiff wire slightly to the drivers side and a little down. about 1/4 inch each. Keep trying.

The drain is located on the rear lower firewall. Use compressed air to blow back into the drain or remove the dash and airbox and clean.

Answer #1 is very good. But it's missing a key piece. The AC drain hole opening is NOT straight back from the opening in the firewall. I had the same problem in my 2008 Endeavor.

The drain hole opening is off center; it's slightly to the drivers side and slightly down and a couple of inches behind the opening in the firewall. From memory, I would estimate about a quarter inch over and quarter inch down.

I used one of those "As seen on TV" sink drain clog cleaners that has the velcro like material on the end. it worked very well.
Just another note, its easiest to reach the opening if you safely put the front tires on ramps or put the driver's side tire up on the street curb to get some ground clearance, then get underneath the car.

Also once you get into the AC drain opening and push through the blockage of leaves/twigs/ etc prepare to get wet. A gallon of water at least must have drained out when I cleared the drain in my car.
Good luck. Hope this helps you.

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.

Water is pouring into the passenger footwell of my 2013 VW Touareg. I suspect the AC drain is clogged. Where can I find the plug & unclog it?

There is no "plug" it is supposed to drain out as it is created, the drain is under the car on the passenger side, it is a rubber tube blow compressed air into that drain to clear the clog (most likely bits of leafs)..

Why does my air conditioner leak water on passager side floor

The Evaporator box has a Drain tube, this is blocked and not letting the water drain off ,hence the build up of water in the box which will overflow into the passengers side .
The drain tube needs to be unblocked to let the water drain off.

Water leaks are fun to trace out. the drain holes and tubes can be seen with roof open and can be unplugged with compressed air . but usually the headliner is soaked and leaks on to seats the windshield will leak on to passenger floor. remove glove box and check for wetness along "A" pillar.

The air conditioner drain is clogged on my lasabre. How can I unclog it?

I usually unclog them using a puff of compressed air. The crud that plugs them is pretty soft and generally is quite easy to blow out. It may plug up again a time or two until the crud works itself out but usually once the drain is finally clear it will stay open for quite a while.

The air conditioner condensation drain is under the hood not inside the car. The fluid is probably a leaking heater coil. It is located on the passenger side firewall.

The airconditioner drain is clogged. How do I unclog. Also there is an odor when I run the air conditioner. Could they be related.

It is definetly connected. Once the drain is clogged mildew will begin to grow.
You will have to get under the car and locate the drain. Usually you can insert a small screw driver in the end of the drain to clear the large debris. Next, use a small bottle brush to remove as much as you can. Next, take a garden hose and run water into the cowling at the base of the windshield. You should start to see water exiting the drain tube.
Repeat as necessary.
Good luck, let me know.
Regards,
Also, once the area is cleaned and dried out, the odor will start to go away.
