SOURCE: Leak into passenger footwell (LHS) on Renault Scenic RX4

It sounds like you may have a blocked drain in the evaporator box. This is where the heater core and evaporator are located.

If you look under the vehicle about where the heater is located, you should see a small tube sticking down ( plastic or rubber ) this should be he drain.

You can squeese the tube open and see if it will drain, If not it may be clogged up with dirt and debris that may require the box to be removed and cleaned.

Check the air inlet, usually located in front of the windsheild, just under the wipers for debris. Keep this area clear. If it has a lot of leaves or other things around it, it can cause water to build up and flood the evaporator box, as well as get down inside.

You may need to take this to a shop that can put it on a lift and get at the drain from the underside, they may be able to clear it without too much troble

SOURCE: 2002 Toyota RAV4 passenger side floor Water

Hi, we also have a 2002 Toyota Rav4 and developed a leak in the front driver's side of the car. After much research, we discovered that the drain wells from our sun/moon roof were clogged. If you have one of these, I suggest that you open the sun roof and look carefully. You will notice some tiny little holes in front and in the rear of the sun/moon roof tracks. Over time, these become clogged with dust and debris. You need to find a long, sturdy piece of thin wire and run it down the holes. To test if you have properly unclogged these, take a small amount of water and pour it down the holes. You should see water coming out of the drain wells under the car around the rear of the front tires. Hope this helps.

SOURCE: floor board on passenger side door gets wet when it rains. i am sure a vent drain is clogged

The drains in the wiper wells are probably clogged. You need to remove the plastic 'vent screen' under the wipers to clear out the debris. Remove the wipers and a few screws, not difficult at all. Also, under the hood, you will see a vertical tube on each side of the car under the wiper wells. These can be removed from under the hood without removing the wipers, but you will probably have to clear the wells anyway. What happens is the water backs up and enters the car through the fresh air inlet and comes in around the blower fan. Good Luck.

SOURCE: when it rains water in in the rear sloshing

The 1997 Sebring convertible has rocker panels (the metal that goes from front to back wheel well and directly under the doors) that have five drain channels each.  The sloshing noise occurs when the drain holes plug up and a rocker panel fills up with water.  Often, the water will then leak into the right rear footwell, soaking the carpet.  A quick fix is to locate the drain holes and run a flat (unused) twistem-tie (they come with your trash bags) through each hole several times.  Commonly, doing so will result in a deluge of water, along with spider web parts, leaf parts, and whatever else washed into the rocker panel fromo the rear window.

To find the drain holes, just 1) lie under the car with a flashlight, or 2) sit alongside the car with one of those mirrors that come on a telescoping stick.  Since I don't like to lie in dirty water, I use the mirror to guide my twistem-tie (or ice pick or spring wire or whatever) into each hole.  NOTE:  the drain holes are flat and run at a 30 degree angle from back to front on the right side and from front to back on the left side.

When first driving forward there is a sound of rushing water heard from passenger front firewall area. is there an area that water can be trapped.


Yes there is. When your a/c runs it creates condensation which collects under the evaporator in a small collector, and then drains onto the ground. This is the puddle of water you will see under a parked car if the a/c has been running. If the drains are blocked the water will not drain away and you will hear water sloshing about. If it gets too full, the water will overflow and you will get water onto the front mats and you might get wet feet. You will need to find the drains under the car and clear what ever is blocking them. It is usually road grime and dirt. It might also be the drains at the front of the windscreen are blocked, although this usually wont end up in the car.

Why does my air conditioner leak water on passager side floor


The Evaporator box has a Drain tube, this is blocked and not letting the water drain off ,hence the build up of water in the box which will overflow into the passengers side .
The drain tube needs to be unblocked to let the water drain off.

My passenger side floor is saturated with water when it rains. When I make right turn I hear what seems like water sloshing.


Hello,
If you can smell a little bit of a sweet smell from the water on the passenger side floor, or if it has an oily film to it, you may have a leaking heater core.

They usually leak on the passenger side floor, and that might explain why you hear water sloshing around.

If you can run the engine for about 5 minutes and then turn your heater on. Look under the dash in the area where the dash meets the floor board and see if you can see anything leaking.

I hope this helps you.

I've got a 2006 Saturn Vue that keeps getting water in the front, under the floor mats. It appears to be coming from the center underneath and behind the instrument cluster/center console. Could this be...


The most common source of water on the floor is a plugged a/c evaporator case drain hose. This drain is generally located down low on the engine side of the firewall at the passenger side and is usually a small short open ended hose that points down. Debris and bugs will clog this hose which makes the water that condenses on the evaporator [whenever the a/c is on] overflow and leak out of the heater/air conditioning housing and onto the floor. If it hasn't rained for some time yet you are still getting water on the floor I would bet on this hose being plugged. A puff of compressed air is enough to clean most of them out. Most sunroofs have one or two small drain holes that allow water to run down through the door pillars and onto the ground. If you pour a small amount of water around the top edges of the sunroof when it is closed you should soon see water dripping onto the ground under the outer edge of the vehicle. A few sunroofs just rely on tight weather stripping to keep the water out but those usually drip water on the driver or passenger if they are leaking. I see a lot of leaky windshields but again, it has to be raining for water to get on the floor from them.

Water sloshing around in the vent, leaking onto passenge floor.


There should also be a drain tube or hole below duct work on outside of firewall or maybe even lower.

Wet floors on passenger side after it rains.


Is it possible the water is actually coming from the A/C evaporator case, whose DRAIN IS CLOGGED ? The water produced by the A/C then leaks out of the case, down under the carpeting, then depending how vehicle is parked, can flow to the rear floors and carpet. Hope this helps
