SOURCE: 2001 Mitsubishi Galant leaks water into passenger

The A/C evaporator drain tube is most likely blocked. If you have a V6, you're in for a real treat trying to reach the thing to clear it. The tube is on the firewall behind the driver's side rear motor mount, and slightly to the left as you're facing the firewall. It is a 1/2" diameter metal tube projecting about 1/2" from the firewall, and is covered by the firewall sound and heat blocking material which has to be folded back to reach the tube. A pair of what I believe are brake lines are one finger's-width in front of it, making it VERY difficult to get to the tube. (Brilliant design, Mitsubishi!) If you are very dexterous, you can slip a small piece of wire or a cable tie under the brake lines and into the tube from the front to try and clear it. Good Luck!

SOURCE: 2002 Lancer heat/ac ductwork leaking water.


I can't believe I found a site that talks about the exact problem I'm having with my '02 Lancer. It must be a common problem for anyone living in a humid climate. The hurricanes here in Texas produce this problem almost state-wide as all of our A/C units are flowing water like crazy right now.

I'd like to expand on the solution that briankc43 so graciously provided above. The drain tube for the condensate reservoir is, indeed, found on the firewall on the driver's side (left hand drive vehicles if there's another). It's a small (1-1/2") rubber tube bent 90 degrees pointing down. In order to get to this tube you will probably have to remove the air intake tube that houses the (I'm guessing here) MAF sensor in order to get your hand down to that area. Once you've cleared the way for your hand the tube pulls off easily from the reservoir drain port that pokes through the firewall. When I did this there must have been nearly 1/2 gallon of water that flowed out! If you have a small, narrow bottle brush it would work nicely raking what muck remains in the interior of the condensate reservior. At this time I do not know if there's any way to introduce more water into the reservoir in order to flush it but this should be sufficient. I guess you could rig a small tube and funnel or syringe to squirt water into the drain port. If this works it may not be such a bad idea to mix a very small amount of bleach into the flushing water to help kill off any fungus as it's a pretty darn good place to grow a fine crop of it!

Because the drain tube narrows by about 1/2 at its end it encourages stop-ups with the dirt and fungus that grows and is deposited in the reservior over time. I thought about leaving the drain hose off but if you did you'd leave yourself open to the possiblity of water getting back into the interior during wet conditions (water splashing up on the firewall) especially if the foam seal on the inside of the firewall was damaged or deteriorated.

I hope this helps those that have been monitoring this site.

SOURCE: water on passenger floorboard when AC is on

You have a bad "heater core". It will leak inside, and outside once the enclosure fills. You need to replace it, or bypass it before your engine overheats and causes a lot more damage. If you're driving the vehicle daily, make sure you check and fill your coolant before you drive it.

SOURCE: 2004 Endeavor A/C water leaking on passenger side floor

Popular question. It's hidden unlike any other car. Outlet is behind driver side brake lines 1/2 way up in a frame weldment bracket hole. Impossible to get to. My dealer drilled a hole, inside driverside airdistribution housing (remove panel next to your accelerator leg) and blew air in it. Lasted 5 min. and plugged again. I found lowest point in righthand corner of housing. You can see molded round shape in housing that leads into firewall. Used hole drilled in line towards back of housing and ran a stiff wire down molded round shape. It went past firewall, felt it unclog some goo, and massive amount of water came out. Sill working.

Why do I have cold ac on driver side and stale air on passenger side. what could itbe? and notice water and antifreeze on passenger side floor board well at least that what it smells like like to me.

antifreeze anywhere inside the cabin is a sign of a leaking heater core. Rub the liquid between two fingers. If it feels oily, it's coolant.

You have a cracked condensation pan on your AC or a bad hose (could be cracked or clogged). You'll need to remove the dash to investigate which it is.

AC water leaks inside car, 2002 mercury sable

You probably have two different issues here.
The water on the floor is usually caused by a drain tube being stopped up. The tube is supposed to let the water drain out of the car and onto the ground. It should be on the bottom of the firewall or below the floor.
You would need to have the computer scanned for trouble codes to find out why the check engine light is coming on.

When i run air condition leaks water on passenger side floor mat

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.

Water on floor passenger side after it rains and after air has been running 2000 grand prix

Ac hose leak?
leaking heater core?

Hint: it leaks when it RAINS

If it were related to the heater core or the AC drain, it would be leaking when it is not raining also, so those diagnoses are not logical.

The grand prix has a long history of floor leaks from seal failures around the air intake under the windshield cowling, where RAIN water runs in.

The passenger side floorboard gets wet =

is it only when the ac is on? there is a pan under the ac unit that has a hole in it to allow the condensation to empty. if that hole gets plugged it could cause the condensation to build up and back into the inside of that car. i unplugged mine and floor stayed dry

Water is leaking in the passenger side floor when the ac is on. 2008 tribeca.

This means your air conditioner drain tube is clogged. This will take about a hour shop rate to repair or if you look behind the glovebox you will see it. Thanks

Water leaking onto floor of front passenger side of vehicle

Water on the floor indicates a heater core leak. You may also find a mist coming from the inside of the car when you run the heat and or AC. If this is the case, have your heater core checked out. Best of luck.
