Water is leaking into the passengers side of the 98 neon i looked for the hose underneath for the a/c evap line it is no where to be found. What can i do?

1--Evap system hoses
2--Purge Valve
3--Check Valve
4--Air pump
5--Canister valve(some people call canister purge valve)

A crack in an evap hose is the most common thing. I would definitely check the two evap canister hoses. These are easy to fine, one being the J hose, which is in a J shape, and connected to your canister and the other end to a valve. Then the Canister Evap hose, which is 18" or so long with a 4" L on the end of it. It connects to a hard plastic or metal hose that can easily be reached by removing the rear passenger side tire on a 98 S70 turbo. Check these 2 first. I found that the cracks in both of these hoses were where the clicks were or close to them(many old style clips causing this). Check these too, again they will both be connected to the canister valve that is right beside the charcoal canister on the passenger rear side.

98 grand cherokee limited 5.2L same problem found leak not from heater box but from drain mount on firewall under the glove box not behind it. drain line should be located behind right front tire in the frame. Turn your wheels hard left look inside fender well right side towards back side. hole in frame where drain line should come out.

IF YOU HAVE EVAP LEAK INSIDE VECHICLE.YOUR EVAP HOUSING DRAIN TUBE STOPPED UP LOOK UNDER VECHICLE NEAR PASSENGER SIDE LOOK FOR THE EVAP DRAIN HOLE USE A SHOP VAC AND SMALL VACUUM TUBE AS A HOSE TO REMOVE DEBRIS FROM EVAP DRAIN HOLE.SO EVAP TUBE CAN DRAIN FROM OUTSIDE OF VECHICLE WHEN YOU TURN ON THE AC.

The usual problem when this happens is that the drain line from the AC condenser is plugged causing it to fill up with water which eventually finds a way out and drains onto the passenger side floor. It is fairly easy to fix but requires getting underneath the car on the front passenger side, locating the drain line, normally a flexible hose coming down through the frame roughly below the dashboard. and running something like a coat hanger up through the drain line to remove the blockage. Beware that water will start to run out the hose as the blockage is removed.
Some cars have this problem more frequently than others and you may have to repeat this procedure every year or so. When it starts dripping water on the passenger side again it's overdue.

Is the coolant bottle actually leaking or do you have a more severe problem? I would start by looking on the ground underneath your vehicle underneath the engine. If its coming from the front look at your radiator first, then your hoses upper and lower then your water pump and finally your heater hoses. If you cant see a leak start the car and let it warm up so your system has pressure to it. Then take a look and please dont stick your hand anywhere around the engine while it is running. Last place to look is feel the rug on the passenger side of the car to see if the rug is wet that would lead to a faulty heater core. If your handy with tools call around to your local auto parts store or tool rental places to see if they have a pressure tester. You can then pressurise your system with this tool and it should help you to find the leak.

I hope this helps you out, and if so please leave me a rating.

first make sure all the hoses are in good shape, if so, it would have to be the heater core or water pump, not sure if you mean it leaking in the floor on the pasengerside, if it is this is definitely heater core, if its leaking on passenger side under the hood its the water pump or a hose

A Large leak is almost never a gas cap, thats usually the small leak. Dodge uses cheap hoses that crack badly. Check the canister in the Engine compartment, passenger side. Then check passenger side behind the cab by the frame. 2 canisters and hoses leaving that ,often cracked. Last is a piece that connects from the hard steel lines near the oil pan....one of these three usually

Most cars have the air conditioner drain on the passenger side just in front of the fire wall , if this becomes clogged it will back up and run out in the area you indicated. Look for the drain hose and make sure it is not kinked or plugged!

The problem you describe could be from condensation. On very humid days, I have seen some condensation from auto air conditioners blow through the ducts. If you run your A/C in the heat/defrost mode (it probably comes on by itself when you run the defroster), that could happen, and the water could be leaking down through the heater vent. It could be a sign that you're A/C unit is low on refrigerant, in which case, you'd need to get the system serviced.

A leaking door seal on the passenger's side could also cause that, but only if it was raining. If I assume that this is happening when it is not raining, the A/C is the only place water could be coming from. The only other, remote, possibility is windshield washer fluid, but you would probably notice that by its odor.

Hope helped (remember rated this help).

I would check the trunk seal first.

1. Thoroughly clean the seal and the surface it touches with windex.

2. Apply a semi thin layer of grease to the seal, you don't want alot just enough to transfer to the other surface when you close the trunk.

3. Close trunk completely and then reopen and examine the grease pattern on the surface it touches.

If there is a break or a messy spot (smear) in the pattern that is where the water might be leaking on from.

could be water pump or hole in hose.
