Wet driver's side floor board

Lately I've noticed that there are wet spots underneath the drivers's floor mat. It's strange because the wet spots show no visible way for water to get there. I'm assuming it's condensation from the A/C. But, I also see that condensation does drain outside of the car. Is there a drain tube close to the driver's side floor board?

Thanks.

Do you happen to park outside frequently under a pine tree?

I once had a problem in a Caravan with needles clogging the drains in the gutter at the base of the windshield (need to open your hood to examine). Wound up flooding the dashboard, I could actually hear water swashing back and fourth at times. Went to a "specialist" that diagnosed the problem, when I picked it up there was another Caravan there, the owner had a similar problem and also parked under a pine tree.

You can open your hood and clean this gutter with a hose yourself, not a bad preventive task to do once a year or so.

Do a search. This was discussed with remedies and even a TSB in 05/06.

A/C drains are typically on the passenger side. You may have a leak in one of the grommets feeding wiring, steering, or brake stuff through the firewall on the driver side. Or, a windshield-to-cowl leak on the driver side. Such a leak would come in under the carpet, and soak it, while keeping the floor mat dry.

This is a problem in older Fords. The drains clog, the cowl rusts out, and then leaks into the interior via the floor vents.

Much to my dismay, I recently discovered my Fairlane has this problem. :cry:

I just purchased a preowned 2005 Five Hundred myself and i also have this problem. One of my mechanic friends thinks it the weather stripping but the floor is not wet anywhere near the door. I brought it to the dealer on monday for the leak and weather striping. Called to check up yesterday, they found the leak, it was behind the dash so that had to be pulled to fix it. They are going to perform one more water test today and hopefully i will be able to take it back today. If you still have factory warranty on the vehicle take it in to a dealer. i could imagine the price if i had to pay for this out of pocket. :shock:

The leak was in a body seam, im thinking this car has been in an accident before :?

My 2005 had the same problem I located the source, and found it was coming from the ac evaporator core/heatercore box which is directly behind the radio and heater controls. If you look just to the right of the gas pedal you can see the bottom of the box meets the firewall. There is a foam seal that seals out weather, the problem is the drain spout which exits out the firewall (about 2 inches long) is slightly angled upward which allow the water to drip right back down the drain spout toward the firewall and then the foam that is supposed to stop water from entering the cabin becomes saturated with water and begins to drip inside the vehicle.I fixed this by taking a hose that snuggly fit over the drain spout and I put a hose clamp on it just to make sure. I did about 2 weeks ago and no wet floor!!! Just a bad design so hope this helps!

Just to clarify the hose I put on the existing drain tube was a 90 degree elbow so this allows the water to drain straight down and not back to the firewall.

I am at my wits end over a water leak on the drivers side floor of my 06 Five Hundred. It's at the dealer NOW and they are yelling me it's a firewall seam that needs caulk... Simple enough???? No, they want a grand, $1000, to remove the dash. The frustrating thing is thing I have the Ford ESP Premium Care extended plan and they say it's not covered. The car is less than 3 years old but has 52K.

I feel SOOOOOO deceived by Ford and the Ford ESP Premium Care extended plan. I specifically asked the dealer when they were putting the hard sell on me if leaks were covered as I had previously owned a Chevy ruined by leaks. They said it was.

I'm expecting this bill to be in excess of $1500 after also replacing the front 1/4 carpet ($500 itself).

DON'T, I repeat DON'T purchase a Ford ESP Premium Care Extended Plan!!!!!!!! There is more in what it doesn't say!

I would call the factory zone rep and ask for assistance from FMC.

AMEN! And tell him that they were yelling at you and don't want to cover what is covered.

I have this same problem with my 2005 Five Hundred. It is not an AC drain problem. I noticed during a heavy rain event water started pouring out of the plastic molding just under the light switch. I waited for everything to dry out and systematically soaked different parts of the car with a water hose starting at the bottom. I was not able to get any water in the car. I know it happens during rains because I have witnessed the water dripping down. I keep a towel jammed up against the molding and it gets soaked every time it rains. Has anyone come up with a fix for this yet?

As a side note...have you guys noticed how dirty the engine compartment gets from road spray/grime that enters near the strut towers and wheel wells?

Same thing with my car. I put a slug piece of hose, angled downward on it and have'nt had water leak in yet.

@ intimidater67 - Where did you get that 90 degree hose from?

Has anyone else solved this problem. I have a 2006 that started experiencing the same issues around 74K miles, been 3 times in the Dealership (b/c under 75K warranty) and the only resolution was the drain for the A/C, they supposedly (I can see it) glues around the firewall, but it is the not hardening glue. It has been about 3 weeks and several hard rains and it is leaking again. You can press on the glued area and it is like a sponge and it oozes out.

Anyone have suggestions?

BTW I did search the TSBs but could not find any that were mentioned.

My mechanic took a hose he had in the back room (just a black hose left over from something else on another car he worked on) that fit over the AC hose. He cut a 4"-6" piece off it and jammed it on the AC drain outlet. The hose had a curve in it already. All you need is to have the water drain lower then the AC hose. The water won't drain back upward after it come out the hose you just added. It's been 2 years since my mechanic put it on mine and I've never had another situation since

Thanks Paul for the information. Is it rain going back up or is it just the A/C and raining has nothing to do with the leak?

Mine was the AC. The AC drain comes striaght out the firewall, no angle at all and when the water got to the end of the hose, it would travel back on the bottom of the hose to that FOAM groumet that holds the AC drain tube. The foam absorded the water and transfered it into the cab and ran down the firewall to the floor board and drenched the whole floorboard and carpeting.

My mechanic lets me in the shop area. Once when my car was up on his lift, I reached up there and grabbed that foam surronding the drain tube. The foam was ringing wet with the AC drippings. It actually ran down my arm and soaked me. That when he put the extra hose on it. Dry as a bone since.

If you do what I did above and you still get water in the cab, I'd start looking for a leak around the door trim or window.

Yeah I will try that, everything you described sounds like mine. This is one thing I hate is water leaks.

Thanks again.

Just jacked the car up and they head told me they extended the drain charged $150 and than ain't nothing on that drain, foam soaking wet and drained down my arm.

Just use a regular hose clamp and rubber hose?
