Water on passenger floor coming from AC drain tube

I have a Dodge ram 1500 5.9 l 1994 . I seem to have a leak coming from the firewall where the AC drain out tube connects on the passenger side floor.I looked at it after removing the rug and saw a round type of housing that makes getting to the tube for clean out difficult. My question is what should I remove in order to see where the leak is coming from. Ive read alot of ideas on it but none seem to address the way to access the tube.From the firewall side its just a 1" tube piece. I even tried hooking a wet/dry vac to see if it would work. No luck.

Are you sure it its you A/C Do you notice this when it rains.
The Dodge Cars have this problem also. Passenger side floor boards.

But it is the Hood hing area.. If the seal is broken there, it allows water to drain directly into the passenger side. You may have to take the hood off to get to the seal.

Test it first, pour some water into the hing area if it comes in the passenger side. There is your problem.

Sounds like the drainpipe has disconnected from the drainpan or evap housing. This is usually in a direct line with the hole in the firewall, so if you are lucky, pushing the pipe through the firewall and hopefully it is in the correct position to fit onto the drainpan outlet. The only other way is to actually do it by feel by sliding your hand up on the cab/dash side of the firewall and locating the pipe and outlet while someone else tries to push it on from the outside. Hope this helps

AC water leaks inside car, 2002 mercury sable


You probably have two different issues here.
The water on the floor is usually caused by a drain tube being stopped up. The tube is supposed to let the water drain out of the car and onto the ground. It should be on the bottom of the firewall or below the floor.
You would need to have the computer scanned for trouble codes to find out why the check engine light is coming on.

Water leaking from ac on passenger side front floor board on 2006 Dodge Stratus.


Look for an evaporator drain that is clogged. You'll find it on the firewall possibly on the underside of the car. It will look like a hose that is coming out of the car and is connected to nothing. You can try sticking a coat hanger gently in the hose to try and dislodge whatever is blocking it, usually leaves.

Where is evaporator hose on 2001 dodge dakota?clean water on floor .


Condensed water from the AC drains out through the fire wall. Check that small tube/hose for plugs. Some models just have a hard plastic tube sticking out and when the seal on the firewall goes bad, the water drains back into the passenger compartment. Add a piece of hose to that plastic tube so it drips down away from the firewall.

I have water on my passenger side floor board is this a ac leak and how can i fix this myself.2001 dodge 2500 diesel


There is a drain for the a/c evaporator core is down low on the engine side of the fire wall on the passenger side. Usually it's a very short open ended rubber tube that's a couple of inches long. It gets plugged up with dust and crud. Once the drain is plugged the condensation that occurs on the evaporator coil builds up and overflows out of the HVAC housing and drips on the floor. I just use a gentle puff of shop air to blow the tube clean. If there's a lot of crud in the housing it may plug up again after a while but usually the tube will get washed clean when the a/c runs again. Hardest part is often just finding where the drain is hidden. If you're having trouble finding it and have a friend or neighbor with a similar pickup it's sometimes easiest to watch where the water is dripping out of his and backtrack it up to the drain. Good luck, hope this helps!

Floor board wet drivers side. No drain tube for ac condensor. Not losing radiator water. Ac condensor not draing to outside. No tube on firewall. 4.2 dohc model


all of dodge models have a drain tube you'll find it over the rack n pinion on the right side passenger but you have to see when does the water comes in the floor board, when you use the AC or when it rains if it's the AC then it's you drain if it's when it rains then you have to check for leaks on your windshield or fire wall

2005 Chrysler Pacifica-Air conditioning leak


The 05/04 Pacifica did not come with an elbow tube on the drain line for the AC drip pan. As you drive, the air flow into the tube pushes the condensate water back into the pan which is inside above the passenger floor board, the drain line is under the hood on the firewall. I spoke with the parts guy at the local Chrysler dealer, he sold me a drain tube for the 06 (~$10) and I installed it, wasn't too hard to do from the top if the engine is cold. The elbow slips on over the drain tube. Make sure to point the tube down. It only took one trip to start seeing water drip out of the tube and the floorboard started to dry up and almost three years later, the floorboard is still dry.
