These are under the vehicle usually parallel to the fire wall and more towards the passengers side tire.

but if it smells like antifreeze then the heater core is leaking

The drain hole is located on the drivers side right above the drive shaft. You will not be able to see it clearly, you will need a piece of wire. I used house wire. You will need to lift the suv off the bround either with ramps or a jack stands. There are two lines running down and about six bolted to the firewall where the drain hole is at. The steering wheel linkage is to the right and the accelator bolt is next to the hole. You will need to reach up and insert the wire into the hole and move it around, make sure that the engine is cool as the exhaust pipe will burn you. Once you think you have it unclogged run the a/c and watch the water pour out. Now that it is unclogged you will need to pull the seat, and carpet out and dry up the water.

Mitsubishi Endeavor 2004. 1. the tail gate and the tail gate glass do not open 2. the AC drains into the driver flooring instead of draining outside to the ground. Why? And where is the output drain...


The door and the glass just needs some penetrating lubricant( WD 40 ), just a few squirt will do on hinges and locks!
The drainage hose would be under the passenger side( RiGHT FRONT SiDE) glove box, look down there, u will see a black hose from the center that houses ur A/C & heater housing! Lift up ur floor covering to see it clearly. check and clean the hose it might already been clogged by moss and dirt or dislocated thru the drain holes on the flooring! Hope that helps out! Taah!

My 2004 endeavor a/c is draining in the vehicle on the drivers side floor board and i took that side up and was water galore. it looks like it is draining from that black drain from the center but does not...


Same thing happened with my 2004 endeavor. There are 2 fixes (as I understand) for this...the first is to get the drain hose blown out. It can get clogged with gunk, then the resevoir fills up with condensation water and overflow.
The other fix is much more involved and expensive. As I understand it from some research I have done, the drainage hole in the resevoir gets clogged with debris that has made its way down from the grill on the hood just in front of the windshield. There is no filter there (Mitsubishi now has one available), so leaf crud, dust and dirt can get drawn into the resevoir and clog it up.
The permanent fix is to pull the AC to get to the resevoir, pull and clean the resevoir, reinstall everything, then put the filter under the grate.
BTW, when my mechanic blew out my hose and was draining the car, he said there is a hollow space underneath the floorboard and it was holding about 5 gallons of water.
So far, running the AC in southern humidity, it has not backed up in about 4 months. I may have to have it blown out again next spring to avoid the water problem again (this was the second time I had to have the condenser drain line blown out).
Hope this helped.

it is a fuse for the glass. The a/c drain is underneath the car, it is not a hose. The drain is located under the hood on the drivers' side. You will have to get under the vehicle, it is to the left of the steering wheel linkage. A bolt is coming through for the accelerator and there is a hole to the left of the bolt and on the bottom of the hole is where it drains from it is like 3/4" down and 3/4" towards the driver side. A stiff wire or pipe cleaner will fit into the nipple, it is not easy to get to but it can be got to. If it is not clogged then it is the actual rubber seal and you will have to find a piece of hose to fit around the nipple and allow all the water to drain through the hose. Hope this helped tim

The system is freezing up,the reason,the evaporator box is filling up with condensation,the drain needs to be unclogged,there is a drain under the car right below where the ac lines go into the firewall into the car.It is hard to find,and you will need an air tank to blow air into the drain and unstop it,water will pour out like mad when it is unclogged.Keeping the cabin filter will help keep this from happening again.If this was helpful,please rate,and thank you.

Can not locate duckbill drain on 05 Endeavor Passenger side of firewall


I assume you are referring to the AC drain.

It is located on the driver side, just toward the center from the gas pedal.

From the outside, you will not be able to see it. It is located in a box in the frame and does not protrude all the way out.
You need to be underneath the vehicle to reach it at all.
On the frame right where the brake line packs turns from horizontal to vertical is a hole roughly 1" in diameter. Facing the vehicle, the drain is in that hole, 1/4" down and 1/2" to the right.
You can feel it if you stick your little finger in the hole so that your finger bends down a little.

If you have an AWD endeavor, this is even more difficult to reach, and should be left to someone with a lift to put the vehicle in the air.

2004 Endeavor A/C water leaking on passenger side floor


You may have to jack up the front passenger side frame enough to get underneath. Please use a jackstand. If you slide under the vehicle and look at the bottom section of the firewall you'll see an approximately 2 inch long by 3/4 inch diameter black rubber hose that is pinched at the end, that is your drain pinch it open and flick it with your finger a few times. If it is badly plugged get a pencil and push it around a bit. Thanks, Dana

Water in driver side floor


The condensation tube is blocked more then likely, a shop can unclog from underneath for about 30-40$. It is usually located near where the a/c aluminum lines enter the firewall if you want to attempt it yourself. If the line is not blocked then the evap box probally has a crack in it and will need replaced

Exact location of A/C drain tube


Open hood, near center on firewall at back of engine, below and about midway between the AC lines and steering column, a small rubber "L" nipple should be visible, if not, line is draining under dash at the firewall, if it is, it may be clogged again. Find a mechanic that you trust and have them them clean it out for you.
