Water leak on the passenger rug for 2003 Corolla

Dear Sir,
I have the same "Water leak on the passenger rug" problem with my 2003 Corolla. And I wen to toyota dealer and checked my car, they told me that I have a leak somewhere under windshield and around firewall, and quote me $500 to fix that. That's too much for me, and I'd like to know if the "condensate drain tube" will be the issue for this, how much that cost?
Thank you so much for any assistance you can provide.

    Toyota EdThank you so much for your quick response. I will show your solution to the dealer and see if they can help me out.
    By the way, if this a common problem, will Toyota be responsible for the issue? I have this issue since I own the car at 2003. I do hope they can do something for this customer on this issue.
    thanks!

    By the way, what do you mean "If the windshield was never replaced, I would HIGHLY doubt that it is leaking." Do you mean replacing the wiper or the whole windshield. I replaced the wiper last year, but never replaced the whole windshield.

    thanks!

    Thank you Sir,
    I will try to check it by myself. But I just realized that I made some mistake on my question. My leak is actually on the driver side and also the seat behind the driver side (the rear seat is worse). So will that be the same issue?



  • ezstudio Jan 05, 2009

    No, I don't have a sunroof.
    Actually, when the car is still in warranty, I had it fixed in a dealer, and I was told that they sealed something around the firewall. But after that I still have the same problem. Just the Driver side and the seat behind the driver side.
    thank you!

    Hi Toyota Ed,
    I went to dealer this noon to check that up, and was told that the condensed pipe was not the problem. The technician was nice and told me that it may take hours just to locate the problem, so it could be costly.
    Thank you for your kind response.


  • ezstudio Jan 05, 2009

    I went to 2 deals already, one said there is some leak around windshield and firewall, which I have no clue where that is. They charged $70 already to check it up, and quote for another $500 to seal that.
    The other dealer I went to today couldn't find the problem, and just told me that they could spend hours just try to locate the problem.

    Any suggestion? I think it is a no win game, since even the first dealer couldn't promise to fix it with charging $500 to seal a leak, too bad -:(

    Hi Toyota Ed,
    I check the chunk and no water in the spare tire area. thanks!
    I do appreciate all the helps you've offered, and I wish you could have a shop around our area, by any change you living in PA? -:)

    any time it rains my passenger rear carpet is soaked. Dealer sprayed it with a power washer and said I must have spilled something. Did you ever get your problem resolved? If so please let me know how The dealership is no help at all, without me paying them some more money.

    Do this: Open the trunk, and look to see if there is water under the spare tire.

    I would like to know what the actual cause of the problem is, BEFORE you pay to fix it. Thanks.

    It still could be water held in the heater box.

    Does you car have a sunroof?

  • Anonymous May 11, 2010

    If the entire windshield was not replaced, I doubt that it will leak. It is what we call "Glued in". Rare for it to leak. Toyota will not fix your issue for free, unfortunately, as your car is out of warranty. I suggest that you follow my directions, check it yourself.

    Save your money. This is an EASY fix.

    GLAD to provide assistance, thanks for the request!

    The condensate drain tube IS a major cause for water leaks on the pass side. Here is what to do:



    Open the passenger side door, pull back the carpet between the floor and the center console. Look for a black rubber hose that comes from the bottom of the heater box, in front of the center console, and pokes thru the firewall. Have a small container handy, and pull the hose off of the heater box, look to see if water comes out. Catch the water in the container as best you can. IF water comes out of the box, your windshield is NOT the culprit. Then, pull the hose out towards you, from the hole in the firewall, and clean out the obstruction in the hose. Let me know if this helps.

Had similar problem with 2003 corolla. Water on passenger side floor, primarily in the back. Water only showed up on long drives, in the rain, with a/c on. Checked floor pan drain plugs first. No problem found. Pulled back passenger side front floor carpet and drain hose from a/c was pulled out. Drain hose located behind centre console against firewall immediatly ahead of where passenger left foot would be. Removed front seat and lifted outside edge of carpet to drain water out of jute. Blew out drain hose and and re- inserted. Done.

Well if you have water or coolant leaking on to the rug in your car, first you must remember that every car has 2 radiators. One for the Engine which is in the front of your car under the hood and one for your heater, which is usually hidden deep behind the dash inside of your car. So if you are leaking fluids on to the rug in the car; Im 90% sure its going to be something dealing with the heater radiator. What you have to do is find out where your heater radiator is on your car and check all the hoses.

Water leak on rear floor board 2011 camaro convertible

I had water behind the seat under the rug and it was the bladder in the car. The water runs off the convertible top and into a bladder that directs it out through the bottom of the car. My bladder/hose broke/came apart and therefore water was now coming into the car under the rug with no visible water coming down the inside of the car. It was fixed by Chevrolet a year ago and now the other side must have let go because again I have water under my rug behind the other seat. I am less than pleased. Car is going into Chevy this week and I will again demand that the rug be replaced after the problem is fixed. If I didn't love my car so much I would leave it there because I am furious that this has happened again

Defrosting vent is steaming out and smells like anti freeze. would it be heater core

It sounds like it, feel the rug on the passenger side if its wet then that will confirm a heater core problem.

I hope this helps you out, if it does any positive feedback would be appreciated. Thank you.

I have a 1993 toyota wish, no manual, and what looks like water dripping out of the plastic trim from beneath the glove box??? I am guessing it must have something to do with the air con?? Help!!! Had to...

It is either water from the a/c drain hose, which, if leaking inside the car is plugged up, and must be cleared (from under the car, the tube is in front of the the passenger area, roughly behind the front tire, near where the passengers feet would be. Use a thin wire to dislodge junk in the tube.
Or it is your heater core leaking, which means it needs to be replaced (you can determine if it's this if the 'water' is antifreeze, by checking the color, and the odor-anitfreeze has a sweet smell.)

1998 jeep grans cherokee leaking water in the

Hi Vichall,

The first step is to locate the leak and identify the source.

Pull the rug back. Dry the area. This will help locate new moisture.

  • Is the water clear? Does it smell sweet?
  • Does it only leak with the engine running? After Turned off? All the time?
  • Does it only leak with the heater on? A/C on?
  • Is your coolant level down?
  • Is their a time of day it happens more? (Early morning)
Comment back with your findings. We can take it from there

Best regards
Mike

My 05 corolla is kept in uncovered storage outdoors and due to my current job it does not move alot. Recently (last 4 months) Every time I go into the car after it rains heavily there is pooled water...

first park your car where the back is flat then spray with a water hose on the back widow only and if you still have water go to a glass shop and let them seal your glass properly water is going in the car because there is a leak in the is or when you drive in the rain the water is coming up in the wheel well

Leaks on inside Toyota Corrolla on the passenger side

It could be water condensing from the A/C and dripping onto the passenger rug. Check under the passenger side dashboard, above the footwell, for the drain pipe from the A/C. If it's loose the water may leak into the footwell when the A/C is running. Should be reasonably easy to fix.

Water leak on the passenger rug

I provided the solution to the link that you provided.
The condensate pipe is your issue, I am sure. Let me know how it turns out; plugged, etc. If it IS plugged, expect a quart of water to come out of the black box.

Water leak on the passenger rug

You may have a buildup of A/C condensate water in the A/C cooler box. Start the car up, and run the A/C; you should start to see water dripping out from under the car onto the street. If not, the A/C condensate tube may be blocked or dislodged from the A/C box. The water then leaks out of the box onto your floor. The drain is on the pass side, under the dash, close to the center console. The pipe goes thru the body. This is a very common issue.
