I have an 03 dakota that had the a/c leak problem into the passenger floor boards.I tried to clean the drain tube, which you can only do if you have the v6 because the v8 is too close to fire wall. From what I have read this doesn't fix the problem anyway. I shoved small tubing in there and vacuumed and pushed air back in, but it didn't fix the leak. If you pull back the carpet you can see a trickle of water coming down the left side angled portion of the floor board. You can find the leak at the skinny portion of plastic condenser housing on the left, which apparently contains the tube. You can't see it but there must be a gasket or something that wears out. I cut back the rubber mat a little bit around the plastic portion where the tube exits. I lightly sanded the metal around where I wanted the sealer to bond. Then I shoved plumbers epoxy all around the tube sealing the (2" in diameter) portion of the plastic housing to the metal floor(firewall).This seemed to work The trickle of water has stopped and the flow of water seems to flow through the tube now. But it's only been a day or two. The plumbers epoxy is the type that comes in a cylinder. It's like a putty, and you knead it to activate it. It has a temperature rating of 250 degrees, which this area definitely doesn't get that hot. The bond strength of this stuff is fantastic. Beats paying $1000 for someone to rip the whole dash apart to fix it. It's really lame that Dodge has let this problem go on. It shouldn't be hard to make a seal there that lasts. This has been a good truck otherwise, but we'll see how many miles I get out of it. This dumb b.s. will definitely have me giving chevy or more likely ford a shot the next go round. I like the scale of the bed for a smaller sized truck. good luck.

2006 Dodge Dakota SLT 4wd Quad cab.
I have water in pass side floor. I believe its AC drain clogged because floor not wet when raining,
The only time I notice water in pass-side floor is after AC use.
I would really like to know where is the drain, I've looked from under vehicle for a drain hose or pipe with no success,I guess with 4.7 v8 the space between motor and fire wall is too tight for visual locating drain.
Can someone Please tell me where the AC drain is located and if its possible to clear the clogg drain.

I fixed my 04 Dakota after years of wet floorboard. Took the
right front wheel off and found the drain on the firewall behind
a small bracket or guard. The factory seal around it had dried
up and shrunk leaving a minute gap atound the tube. After
applying a high end sicone gasket pucky that cost @$8 a tube,
and only used part of it, so far it's been two years with no more
wet floor. Easy to find with the wheel off. You can feel it from
the top but its almost impossible to see and certainly
impossible for me to reach down and apply the silicone. Jack it
up and block it up, remove right front tire, and easy, easy,
easy then. Guy at a small town dealership told me he'd do it
for $300 or I could do it for $10. He was dead on. Thanks!!

Mine (2005 Dakota) was a gasket in/around the evaporator case for the A/C. It is up under the dash, inside, on the passenger side. Shop "fixed" it then water came right back - rain or not. They checked it and said their guy had pinched or damaged the replacement seal. They did it again at no charge and threw in $80 install of Ice32 in the compressor for free. Bone dry ever since. ANOTHER leak I had and fixed: the third brake light up on the cab roof. Had this filmy little "gasket" - what a joke. It let heavy rain wet and stain my headliner. I took out the two screws - laughed bitterly at the outrageously crappy "gasket" - gooed it all up on the lens with the black silicone - good to go. NOW my headlight lens' are yellowing. Going to try the YouTube trick using TOOTHPASTE to clear them up.

I know this is an older post, but it is one of the first ones that comes up when you Google this issue. I thought I would post a link to a video I just did on the AC leak fix for a 2002 Dakota 4.7L Quad Cab. Previous posters are correct in that you have to remove the passenger side wheel and fender cowling to get at the drain tube.

I hope this helps!

This is a pretty old thread, but I will go ahead
and add to it since it was helpful for me. I was
convinced my 2007 Dakota water on floorboard
problem was rain related, partly because the A/C
drain problems seemed to be all the previous
generation Dakotas. I assumed they fixed that
problem, but they didn't...
On my 2007, it is not a tube that goes though the
firewall, but an oddly shaped rectanglish drain,
with about a half inch gap all the way around it.
The "seal" is a very squishy pores feeling foam.
The design problem is that the drain just butts up
against the heat shield behind the engine, which
fills up with water, and makes it way back through
that foam around the drain. I cut away the heat
shield and sealed the gap with some high heat roof
repair seal, but with the heat shield gone, it just
drips directly on the exhaust which can't be good.
So I fashioned a gutter out of a piece of tin, and
bolted it to the firewall with bolts that were
already in place. This seems to be working in
testing, and water is not coming inside. But be
prepared to remove the front right tire and fender
skirt. I had to drill out all the mounting pieces.
If there is a trick to get them off and reuse them,
I don't know it. I have replacements from a kit I
got on Amazon. I hope this helps other people with
the same issue. I just wish I was able to post
pictures, but it doesn't seem that I can.
