Question about 1994 Jeep Wrangler

I have a 1994 Jeep Wrangler. After it rains,

I have a 1994 Jeep Wrangler. After it rains, water comes out of the ventilation system onto the floor of both the driver and passenger sides. This usually happens when rounding a corner. If I am running the defroster or heater, the windows will immediately fog up. What causes this and how do I fix it?

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.

You need to locate your drain hose or port, and clean it out, which is probably clogged with debris. Best thing is to try & remember if possible, where you seen water dripping under vehicle when AC as on & vehicle was sitting on hot summer day in a parking lot or in driveway. Normally it is more on passenger side, sometimes coming out of firewall , down low. Look for a rubber tube like piece, or even a short,round piece of plastic like sticking out somewhere in that area. When/if you find it, poke a piece of coated wire or something similar up through it to unclog debris & get water flowing out of there again. Don't poke anything hard up there, especially too far, and damage something else, only far enough to unclog it.

Water leaks into rear left cargo area in 2006 Jeep Liberty during heavy rain. Think it's coming from roof rack but no water comes in when I aim a hose at it.


Could be the rear wheel is splashing up the water onto the cargo area, only when you drive. It might be a hole in the floor of the cargo area letting in the water.

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.

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.
