Leaking from passenger side floor board jeep grand?

Answer 1

heater core may be leaking, check to see if liquid is antifreeze, use a white cloth to see if fluid is green or pink. smell may also indicate what the fluid is. if you are low on antifreeze in radiator that may be the cause. a heater core can be purchased at any auto parts store & can be installed by anyone with general knowledge of tools & automobiles. The wetness can also becoming for the air conditioner. If this is happening during the summer, that is probably the cause. Check and see it any of the drain holes are plugged up with leaves or dirt. I believe either the evaporator or dryer is also behind the dash.

I, too, just recently discovered this problem. A couple weeks later I discovered the entire passenger side was full of water. Hey, that nicely constructed, one-piece carpeting makes a great sponge it turns out!! Pull down the carpet in the front to look for water. I'm willing to bet you have it there, too. It's either the a/c water discharge hose is backed up or you have a rainwater leak somewhere. You can find plenty of info on the fix for the a/c hose clogging. You'll have to drill a hole through the plug, ect. You can find past recall notices on this very problem with very specific instructions to cure it. (or you can remove the entire dashboard) A water leak will just take time. In my circumstance, I read on this site, pulled the carpeting back some in front, sucked out all the water I could, and then used the a/c to see if it happened. After a week, I'm convinced it's a leak somewhere else as there's been no leak from simply a/c usage. But last week I drove from Indy to Hammond in a horrendous downpour for 3 hours, and later found the water in the back seat and - lo and behold - actually the entire carpet was soaked. This carpeting can hold a lot of water!!! So check it out, and good luck to you. After 227,000 miles on my '97 JGC Laredo, this really is the only real problem I've had, so I guess I shouldn't complain...

What you're seeing is an air conditioning system that's all plugged up. The evaporator box that condenses the water from the inside air (this box also contains the heater core) is located on the firewall up by the front passenger side. This is a black box that sticks through the firewall by the passengers feet. Inside the condensor box is a thin styrofoam liner that is designed to prevent condensation from forming on the outside of the box. Water drawn from the inside air collects and is supposed to drain out the bottom and down to the ground. Also inside the box are coolant lines that come from the radiator to make hot air via the heater core during the winter.

So this is the problem: The styrofoam liner breaks up and goes into little pieces and the air that is drawn though the evaporator box has lots of dirt in it and all that stuff clogs up the system. In typical systems the dirty water goes from the bottom of the condensor box to the ground via a rubber hose but in our Cherokees this water drains from the bottom through a little hole and into a frame member. Cherokees are built on a unibody and therefore do not have a regular frame under them. When all these parts become clogged with styrofoam and dirt the system backs up, the condensor box fills up with water and it leaks all over the passenger floor and beyond.

The fix? Sadly, because of this poor engineering, the whole dashboard has to be removed in order to get to the condensor box to clean it. While the dash is apart the air ducts should be cleaned of any styrofoam etc and the heater core should be replaced. At any AC/Heater shop this job will take at least a day or two and will cost you around $2000.00. This will be, for a 95 perhaps more than the vehicle is worth.

Wiki is full of other fixes that can be done which include things like drilling a hole in the bottom of the evaporator box and running a new hose through the floorboard etc but if you want to do it right, the dash has to come out. I tried that once with one of my previous 95 Cherokees and it sat in the driveway for two weeks while I tried to figure out what screws to take out next and I never did get it done completely right. This will not be an afternoon project if you decide to do it yourself. Bear in mind that if you decide to drill a hole in the condensor box that the heater core is immediately on the other side of the plastic and if you put a hole in that with your drill you'll have a much bigger problem than water on the carpet.

Answer 4

Probably a leaking heater core or hose to or from it Probably a leaking heater core or hose to or from it

Answer 5

Ive had several heater cores go out in most of my cars and that's a sign of the heater core beeing clogged or not working correctly.

Answer 6

some pump underneath the passenger side floor is clogged. unsure of what pump it is though. Mine was like that too. Cost around $200 to fix.

Answer 7

Check the Sun Roof Drain. It runs down the passenger pillar. It may be brittle and broken.
