SOURCE: Have a leak under passenger side dash when it rains. I think the door under the cabin air filter isnt closing is it an easy fix

Having just repaired this problem in a 1998 Buick Regal, I can tell you that fixing the water leak is actually quite easy. It took me quite a while to track down the source of water, but I have discovered that it comes through the cabin air filter. There is a seal on the passenger side of the cowl (A two piece unit, black plastic, against the windshield) that seals it to the windshield to prevent water infiltration. It is very small and somewhat hard to miss. I took the cowl off to change the filter when I discovered this.

You can make a diverter to go over the air filter under the cowl, or even easier is to use some clear RTV silicone (avalible at any automotive and most hardware stores) and put a good bead on the old seal. When you re-install the plastic cowl, be carefull where it goes against the windshield to make sure you don't "smear" the silicone. After you re-install the plastic retainer hardware, smooth out the bead and clean up the excess silicone(a wet finger and some old cardboard works great). Let it dry and clean up the water in the passenger compartment.

Cleaning up the water is the hard part. Removing the plastic trim around the door (if you grasp the trip peices firmly they just pull up off some metal clips,but they can be quite stubborn) you will notice the carpet just pulls up. At the bottom front corner of the front doors the carpet has a plastic hook that is around one of the trim clips. Lift it off that and the rest of the carpet towards the firewall just pulls up. If it has been a long problem, your carpet may be moldy. Also, the carpet edges and some of the more hidden panel clips are very sharp and may cut you while you are poking around, so be carefull.

Since the water entered through the air filter and right over the fan, you will at minimum want to replace the filter. I had mold and moss growing on mine. My fan also squeels and chirps now, so I know it got wet. Not much to do about that but replace it or carefully lubricate the motor.

In your question you mentioned a door underneath the filter not closing. On my '98 Buick Regal there is no door or valve of any sort. The filter sits right above the fan blades. It is the cowel's job to prevent water from entering this part of the vehicle. I hope this helps you fix your problem.

SOURCE: driver side floor water leak

Well, you are on the right path; the rubber seal around the windshield could indeed be deteriorating...what may be happening is the water is coming through the cowling and pooling up on the seal there...as the water sits, the seal deteriorates and eventually you will see water like you are now.

My recommendation to you is to take your Edge to a shop and ask them to look for a leak at the bottom seal of the windshield.

SOURCE: have a benz 01 ml320, with leaking sunroof drain on

Open up the sunroof and try to unclog the drainage. You will see this from the inside of the ML by opening the whole sunroof and stickin your hear thru. On the drivers side you will see a drainage whole similar to the passenger side. Mine did the same thing and unclogged it with a straw. ljsloan@gmail.com

SOURCE: Air Conditioning water leak inside

The drainage tube for the evaporator case is plugged causing the the condensation to drain inside instead of outside the car. The car will probably need to be lifted to find the drainage tube. Use a pick to gently remove the debris blocking the tube. You must be very careful as not to puncture the evaporator core.

Water leak driver floor board


You have to find the leak
Have a shop use their Evap Smoke Machine
Pressurize the cabin & see if smoke comes out
around the windshield,engine compartment,etc
Hate to run hose over the car, but you can see it come
in,so that is an option,with someone under the dash with
a light watching.
Check on internet for the issue on your vehicle
Call an auto glass place, for advice on what they solve

Rain leaks


NO, it is most likely getting in through the cowl vent area under the wipers. Normally the water drains out the inner fender, but if its clogged with leaves and pine needles, it wont drain and will fill up past the cool air intake and get into the cabin. I would pull the cowl vent grille and make sure the drains are not clogged.

2005 Elantra leaking under the dash on driver's side


It is more than likely coming down your Cabin Air Filter into your HEATER BOX adn then onto the Floor.

If it happens when it is Dry, then you have a hole in your Heater Core....

Rain water under dash


Hello, You may have a potential claim under your Car Insurance for Comprehensive which may have no deductible.

There is every potential for water damage to the components under the dash besides the rust of the metal dash framework.

Your windshield seal may be leaking and a simple removal and replacement of the seal by a Glass shop may fix your car. But there may be other wiring "boots" going through the firewall and those chassis seals may also leak.

You have a problem which does not necessarily have a bolt-on solution except possibly a worn door hinge pin allowing for a leak to run along the top of your door weatherstripping and into the dash on the drivers door jam.

There are a number of paste or tube type gasket sealants. But you would want something like the glass shops use. The fumes from some of the products are meant to be used under the hood and not inside the cabin where the people are.

Check with your insurance company, often Comprehensive does not raise your rates if you need to use it. Otherwise if you want to fix it yourself, look for water tracking. You could also position yourself under the dash and have a helper spray a garden hose on the car while you look for the water to enter.

I have a 96 jeep grand cherokee straight 6 with 102000 miles i just found what appears to be water leaking inside the cabin under the passanger side seat and rear left side.


The drain for the water coming from the ac is clogged. Clean it up. It's easier to do that from underneath the car - the drain is located on the firewall.

Since I purchased my 2000 GMC Yukon XL 1500 we have had a water leak that soaks the drivers side floor and passenger floor behind the drivers seat. I took it to my GMC dealer and they had it two days and...


You may be right about the sun roof. It should have 4 tubes to drain water that comes in around the glass. Sometimes the tubes fall off letting the water come into the cabin. The horn may be the part in the wheel. Apply it at different angles and it might start working. Sometimes they get rusty. I think your cabin filter would be under the hood near the firewall on the passenger side with a plastic cover.

2005 Toyota Corolla - car smells after rains


Look under the passenger side of the dash, behind the carpet. Feel the back side of the carpet for dampness. If so, try this: In the same area, look for a black rubber hose that comes from the heater plastic box, and pokes thru the firewall. See if it is plugged up. This is the drain pipe for the AC box, and the cowl panel if the side drains are plugged up. Try that, and please get back to me.

1998 lincoln town car


If you notice a 'sweet' smell, or windows tend to fog up, it's your cars heater core leaking. The heater core is located under the dash, passenger side, it's like a mini radiator. The cars cooling system directs hot coolant to it so you can have heat. To change it is an involved procedure.
If there is no evidence of the anti-freeze smell or windows fogging up, and u have been using your air conditioner, it would be a blockage in the drain tube from the a/c. The end of the tube is located under the car on the passenger side , behind the front wheel. The blockage needs to be removed, and will solve the problem. Let me know what u find Curt
