hey just wondering if anyone knows about our heater system in the car is there a shield over the vent to prevent water from entering the pollin filter i believe its called? i'm having the water in floor problem similar to that of the ford tauraus from what i've read online where the shield is knocked off and my heater fills with water and pours onto my floor when full

And there isn't a "cover" over the screen either. If there isn't any moisture on the upper part of the carpet check your passenger front door seal. Mine was leaking in at the bottom. It was runing down the lip and flowing in where the inner door sill molding snaps over the seal. I poked some holes in the outer part so the water would drip outside instead of flowing into the car. Haven't had much liquid percipitation to see if this actually works, and now I may never get to know...

Do you know if there's a body plug there or a seam on the outside?
I would look but I'm at work. My Jeep had a body plug rust through, letting water in. Of course I didn't notice it till the floor pan was rusted out. The hole was on the bottom so it never held water, just moisture. The best thing you can do is get someone to spray that side/wheel well area with water while you are in the car watching for the leak, and that can still be a PITA.

Water leaks in that area (well, any area for that matter) can be hard to track down because water will travel to the lowest point before falling to the floor, or pooling up on the floor. Is the water dripping from the HVAC box? If so, is it coming out of the seam where the two halves come together? Or is it running down the side of the box? If it isn't dripping from the box, is it running down the A-pillar and pooling at the carpet?

The best way to diagnose this is to do like the glass shops do. Have someone run a hose (low pressure, light steady stream) over one set area at a time. You have to be a contortionist to look under the dash to observe the water entering car. Once you have a place where the water from the hose starts coming into the car, start your focus in that area. Start at the top and work your way down.

It's not fun, but unless something is obvious, it's the only way. Good luck!

it makes a really weird sound when it happens almost like ouring water on a hot surface

If it happens when your heat is on (and warm) it may be water hitting the heater core.

is there an arear there that could hold water? because it seems like water is pouring into a pocket of some sort and when i start to move the car or turn is when it most oftenly happens

It's possible. There are too many areas to look at, and without seeing the car and using the techniques I outlined for you, we could guess at it all day. No easy fix on this one I'm afraid

does the water have a smell? ... if it does then it may be the heater core it's self that is leaking

Do you have floor mats that keep melted snow from you shoes from soaking the carpet? also check your door seals like I mentioned above. I usually put a small towel in the floormats to soak up excess water, and wring them out, but this only works with mats that have a large lip to keep water in. But the door seal thing is hard to detect, since it runs in directly to the carpet.

i'm betting thatswhat it is on the drivers side because when i was looking at my mat (the carpet one) it seems start down the the seat near the door so maybe it is the seal on the door how hard is that to fix?

Another common area to check...are the rear floorpans wet when the front is? The tail light seals (lamp to body) are known to leak. My car had had a leak on the passenger side, ran into the trunk, under the back seat, and pooled on the rear footwell.

this is in the front you can see the water on the floor pooling outwards front drivers door, on passenger side its the same coming from passenger door

HEATER CORE!!! you said that you keep pounding the heat. that's your issue. the more heat you're pushing the more COOLANT comes in. check your coolant levels in the system and the overflow. i'm willing to bet that they're low and that you need a new heater core

w0158981 · Post by **w0158981** » Thu Feb 21, 2008 12:15 pm

ok how do i check my coolant levels?

Post by **occasional demons** » Thu Feb 21, 2008 12:32 pm

Keep an eye on the overflow bottle on the firewall should be by the brake booster. If it's empty add some coolantwater to it and also check the fill cap on the head where the upper radiator hose comes out. If that's low fill it too. When engine is cold then run the car to operating temp and let cool completely and note where the level is in the overflow. if it steadily drops over the next few days it's leaking some where. Or you can rent a pressure tester from Autozone or buy from a parts store/online, and pressure test the system. if the needle drops then there is a leak, and it makes it eaasier to find.

SYMPTOM/CONDITION:

Water on the right front passenger floor.

DIAGNOSIS:

Run water over the right lower A-pillar with a garden hose. Remove passenger side cowl trim and pull back floor carpet to confirm water leaking into passenger compartment. If water/leak is present, perform the repair procedure.

PARTS REQUIRED:

REPAIR PROCEDURE:

1. Open Hood.

2. Remove the three screws holding the cowl grille/screen on the passenger side of the vehicle.

3. Partially remove hood to cowl seal, at the leading edge of cowl grille/screen.

The sealer beads are at the junction of the A-pillar, cowl plenum upper and cowl side panel. Apply Mopar Silicone Windshield & Glass Sealer, p/n 04467708, to the outer edge of all existing sealer beads.

7. Allow sealer to set up for 30 minutes. Water test right lower cowl area to verify repair. install passenger side cowl trim.

8. Reverse above procedure to install the cowl grille/screen.

read post #20 five more times.

And turn your hvac controls to inside (recircilated) air before you get out of the car until you fix it.
