    yeah i don't have a sunroof, so i'll look into the heater core. why does the heater core leak onto the floor? regardless, i'll look for a chilton's at the library. can you explain the kit that kills the mold? thanks so much! respect.

  • rayportante Nov 10, 2008

    the Chilton manual tells me that i need to get the A/C discharged. is that necessary? if so, what is involved?

  • rayportante Nov 10, 2008

    it's the standard 4 cylinder, not the vtec. the more i think about it, i'm going to call a few mechanics because i don't have specialty tools and i'm not a pro. i'll try the lysol idea and let you know how it works.

There are basicaly only 2 things that can leak onto your floor boards the first is your cooling system. If its your cooling system the only part of your cooling system that comes inside your car is the heater core. The 2nd thing that does happen but is unlikely, is if you have a sun roof. There is a drain and a tube that goes down to the doors. if its clogged instead of going down to the doors, it will over flow and spill under the head liner and flow to the floor. But because your widows are getting wet also I would bet its your heater core.

In most cases Heater cores are pretty easy to replace. they are usually located behind the glove box, but can get more difficult depending on the make and modle. I would purchase a Chilton. You can get one at the part store. Dont get a Haines, they are often difficult to read and are not as easy to use. Also Honda's are notorious for A/C mold, but you can buy a kit that you put down the vents that kills it. You should be running the vent with just air not A/C to dry out the vents every once and a while that will help keep the mold down also. Hoda's and Toyota's vents are so well sealed that they are natural borne mold growers. The dealers also have some kind of mold removal thing they can do but as far as I know its the same as what you would buy at the part store. you may have to do it more than once, mold is not always easy to get rid of.

    what engine does your accord have, is it the 6 cylinder or 4 cylinder and if its a 4 cylinder is it the vtec?

    although its good to follow directions. Not every direction is always required. I swear by the Chilton Manuels, but I also pick and choose what I will do. So if a step can be skipped without getting in your way or causing a problem, I don't see why not. I have never, ever drained or pulled the A/C system to put in a heater core because they don't cross sections in any of the cars I have ever worked on. Not saying Hoda didn't do something wierd to cause the do it yourselfer a big problem.

    Now I do see that you are basically going to have to remove your entire dash no matter what engine you have. I have done this before on a couple other cars. This is not for the beginner. It will take quite a few specialty tools and expierience that comes with a lot of other jobs. If you take this job on, and you remove your dash. Just remember the big problem isn't fixing what you saut off to fix. Its putting the dash board back on with all the screws bolds and pins. Without it sqeaking and making noises for the rest of its life. Getting all the litle spots to align up and match where they go. You will need some one to work with you and to help lean it back and forward, and if they are not working with you, they will DRIVE YOU NUTS!!!!!!!!!!!



    This may be one of those jobs you start taking bids from all the mechanics around town, and Just save up and get it done by some one else.



    As for the mold kit,



    Ok, Honda's are quite air tight when all doors and windows are closed as the pressure releasing vents (that are typically found under the back bumper fascia) for door slamming etc. are a bit too efficient at sealing when not in use. This results in the smell that is normally caused by mildew(mold), and always turning off your a/c before you arrive somewhere (3-5 mins if possible) will help dry out the exchanger and avoid the problem.

    Once you have the mold, Lysol does kill it. It's also much safer than spraying in a mixture of bleach and water (bleach kills mold as well, but also can take out dye in carpet/upholstery).

    The one thing newer Honda's have that older models don't is the fresh air filter. I'd suggest:

    1. Removing the fresh air filter and replacing the holder (so it seals).
    2. Open the hood and secure with it's holder.
    3. Let the car idle with the a/c on and full fan. Be sure you are NOT on recirculate.
    4. Open all doors and windows and do not let anyone sit in the car.
    5. Spray 1/3 to 1/2 of a can of Lysol into the incoming air ducts at the base of the windshield.
    6. Turn off a/c, fan and shut off the car while letting it air out.
    7. Replace the fresh air filter.

    That should do the trick, just remember that the first usage of your HVAC system after this will be VERY strong smelling of Lysol, so the use of a scented type (fresh linen is not bad) is warranted. May want to crack the windows for a bit .

    Hope that helps someone out.

    If not a newer model you will have to put the fan on not the A/C and spray the lysol in under the dash where the intake is and you will have to do this several times a year.

    Correction to the last part leave the A/C on while spraying your Lysol, and turn the fan on full blast, sometimes my fingers and my brain don't work in tandom.

What is causing water to leak down onto the floorboard of my 2004 Mazda 6 when I have AC on?


this will be condensate from the fins of the ac evaporator in the car and is leaking onto the floor because the drain on the unit is blocked either in the hose or at the bottom of the ac box

What is causing water to leak down onto the passenger side floorboard of my 2004 Mazda 6 wagon when I have AC on?


Feel the water and smell it. If it smells sweet and fells oily, is is coolant. If is isn't oily and has no real smell, it is water. There is a tray under the evaporator and heater cores that catches water/coolant and drains it via a tube thru the firewall to the outside of the car. This tube is probably clogged and needs purged. If you have coolant on the floor, you'll need to replace the heater core. If it is water, purging the hose will solve the problem as the water is just condensation from the AC coils

Air cond. don't leak onto the ground


If you mean the condensation water from the a/c - the drain tube is probably gunked up.
There is a small tube or hose near the passenger floorboard that the water drains thru. You should be able to see if from under the truck.

Water leaks onto the passenger floorboard during heavy rain


Floor plug or plugs have fallen out most likely.There Should be some plastic plugs under the floor board outside. Look to visualy check to insure they are still in one piece.

A busted heater core will flood the passenger side floorboard when the heat is turned on.

Fluid leaking onto the front passenger side floorboards.


2004 TB 60,000 miles. i was just told that the leaking fluid in my passenger side floorboard was do to a clogged up A/c hose. An A/C works by drying/ removing the moisture from the air inside the vehicle and cooling it. The accumulated fluid is usually evacuated under the vehicle which is what you see when people are stopped at a red light and there is dripping under their car. when a hose is blocked there is a vent that from some reason flows directly into the passenger side floor board. If you can not manually knock loose the block your probably going to have to take it to a mechanic.

Leak onto floorboard


Here is what all dealers do to find water leaks, we spray a fine mist of water on the car near where the water might be comming in with a spray nozzle, someone gets inside the car and look for the leak, there is no other way, and I have been doing this 30 years.
