Your air conditioner evaporator core drain is most likely plugged up. This small drain is located down low on the engine side of the firewall on the passenger side. Usually it's a little rubber or plastic hose that points out or down and is about 3/8" in diameter and a couple of inches long. It gets plugged up with dust and crud and causes the water that condenses on the evaporator core to fill up, overflow, and drip on the floor from the heater & a/c housing ductwork. Usually a puff of air will clear the clog although sometimes you may need to clean it a couple of times until all the crud comes out. Once the drain is clear and the a/c is running then you should see water dripping out of it after a few minutes of operation on a humid day. Not hard to fix but the drain can be hard to find. Hope this helps you fix your problem!

06 wrangler leaks on drivers side floor when it rains

I had the same problem, but on the passenger side. This may help. Look on the inside under the door for a seam where the two body panels meet. The seam should be tight, but mine had a good size gap and the water was coming in there. I took a tube of caulk and kept squeezing it in until it came out. No more leaks and I used to get a lake on the floor.

It must be a soft top? but if not does it leak when you turn or is it there in the morning when you get in? It could be the vent on top right behind the hood

Water leak to floorboard on drivers side. Carpet wet all the time with standing water. My Jeep is a 2007 Wrangler/rubicon

It it happens when it is raining. This seems to be a common problem with Vehicles.

There is a seal on the passenger side Hood Hinge area. If this seal is cracked or broken or missing you will get water in the car every time it rains.
The water runs down the windshield in to the Hing area under the Hood.

You may need to take the hood off to get to the seal. First pour water over the area, if it comes in the car there is your problem.

You can seal it with any water proof silicone sealer .

Water Leak in Passenger Side Floor Vent Area after car wash

Unless this happens in the rain as well, I would not worry about it. Likely in the car wash, far more water is coming in than the normal drain system can handle, therefore causing it to overflow. If you do have a drain obstruction, find the drain hose (small right angle hose on firewall passenger side) and roll it in your fingers to clear it.

I have a 1994 Jeep Wrangler. After it rains,

First make sure it's not antifreeze which I doubt it is considering it only happens when it rains, it is probaly a clogged drain hose for the vent chamber which is located at the base of the windshied,or it is a clogged drain for the a/c evaporator box, if you can find a small drain hose or orafice under vehicle toward the base of the fire wall under vehicle you could feed a length of wire up through to unplug it, a mud wasp is the usual suspect planting a egg and packing it with mud to seal the deal.

1999 Jeep Wrangler 4 cylinder (manual tran). I noticed a large pool of water in the floorboard on the passenger side of my Jeep. This was after driving for about an hour with the a/c on in Texas at about...

My dad has a 2004 Dodge Dakota with the exact same problem, the passengers side floor board is soaked with water after running the AC. Also there is a pool of water that collects under the truck.

We are getting a mechanic to look at it, I will post what the problem is when we find out.

Water on floor board of Jeep Liberty

It is most likely coming from a dried up or improperly installed window seal at the bottom of the windshield (under the wiper trim)

Take the trim off and caulk yourself - or have the entire seal replaced.
