My wrangler was doing the same thing. As it turns out the condensate dripping from the drain tube was running back toward the firewall along the bottom of the tube and was getting past the foam gasket which wasn't sealing off very good any more because of age, dry rot or for whatever reason. The solution: Go to the parts house and get a bypass hose, which is a piece of heater hose molded in a 90 degree bend. They will have one that fits snug over your drain tube. You could even put a bit of black permatex inside the hose to help seal but I didn't need any. Now the water drips out below the hole cut into the firewall preventing the liquid from getting into the cabin of your jeep.

Good luck!

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.

Lots of water in my driver side floor board, where is this coming from? 2007 Jeep Wrangler

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!

2000 Jeep Wrangler 4.0 liter: Air conditioner drips condensate on passenger side floor. Is there a drain somewhere that could be plugged?

There is a drain tube on the lower part of the firewall that is probably plugged.Normally I use a pick to dislodge debris some use coat hangers but you must be careful not to poke at too hard and cause a freon leak in the evaporator core.

Where is the jack located in a 1999 Jeep wrangler

The 99 TJ Wrangler has the Jack strapped to the floor board under the passenger seat, tilt the passenger seat forward toward the glove box like you would if your were getting into the back seat and then you should see it strapped to the floor directly under the seat.......My guess is that if the Jack is not there then it's probably missing if you purchased the Jeep used from someone else.

Its leaking under the dash on the passenger side when the ac is on, it feels like condensation from something under the dash but its alot and is soaking the floor of the front passenger floor

The water is probably coming from the air conditioner. Check the air-conditioning box or ductwork that surrounds the evaporator. There should be a drain hole in the bottom for the water to escape to the outside of the car. The drain hole may be plugged or the ductwork cracked or broken.

Also, this video can help as a reference guide...

Hope this help.

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 leaking on passenger side of 1999 jeep wrangler

If you look on the engine side of the firewall on the passenger side about even with the bottom of the heater box, you will find a short pliable stub hose. you can clear it by rolling it between your fingers or using something soft and inserting it into the hose (using anything hard or long can damage stuff inside the box) Once cleared, you should have no more problems.
