A few days ago I noticed moisture in the driver's footwell. I dried things out, confirmed that the sunroof drains worked and that the drain holes by the fuse box and battery were clear.



With heavy rains in NJ over the past two days I have water UNDER my driver's mat. The drain holes beneath the fuse box and in the battery well are both still clear. Water does not seem to drip on my feet. When I checked under the mat yesterday morning before driving to work after heavy rain the night before the carpet was dry. When I left work yesterday afternoon after still more rain the carpet was wet. It almost seems as if the water entered while driving, not while parked, but I am not certain.



Any success stories on this problem would be greatly appreciated.



Thanks,

Charlie

Charlie, that sounds somewhat similar to (one) problem I have on the passenger side. I can see water running down the carpet on the kick panel, then it hits the floor and, in my case, not only soaks the carpet there but runs along the channel between the side and the rocker panel, filling the rear passenger foot area. I've deduced (but not proven) that the water is getting behind the A-pillar seal and then taking the path described. I'm going to take some black sealant and try getting a renewed bond established. At worst, if that doesn't work, I'll purchase a new seal and install it. I seem to recall hearing that those seals are pretty pricey, so I'll do what I can before going that route.

if it's the one that goes up the a-pillar across the top of the windshield and then back down and the top rests down on it, sit down - $600!!

Wait. Charlie has a coupe, right? He mentioned sun-roof, so a cab-related seal can't be involved.

Right - Charlie has a coupe; I have a cab.

Anchorman, I know you have a cab, as does Flash. It seemed that Flash was describing a cab-specific seal. That's all.

yes i was - it was more to jim's thing than charlie's



lots of places to start looking - get comfy, get a flashlight, and get someone with a hose



battery box - windshield seals - window seals - heater core seals - wiring harness - those are good places to look for the water - dust them all with flour or talcum powder (if you use flour, make sure you clean it all up or you will get a yeats smell later) - then hose down the car - look for wet white stuff

A note on the water test..... When you start to hose it down from the outside, start at the lowest point where you think it may be entering the cabin, then work your way up SLOWLY. Do the same thing with the water pressure, you do not want to force the water uphill with strong pressure, start off gently. Sometimes it takes much longer than you might think for water to sneak its way in. When we do forensics on a home this is similar to how its done.

Thanks for the suggestion, SilverBLT (BTW - every time I see your sig, my first thought is lunch). I've removed the interior A-pillar panels so that I can see if there's any signs of water penetration in that area. No water tracks are noticeable, but I'm hoping.

I don't pretend to know anything about fixing these babies but...



Bob Kovacs at the 968celebration suggested that a major cause of leaks in the footwells (particularly passenger side...but who knows water can travel) is rust under the battery. He suggested that he has seen this problem often enough to write an article about it.



He discussed removing the battery and using a dremmel tool to remove the rust, then seal the battery pan with fiberglass.



Just my humble offering

Hey, no suggestion on my part... I said it loud and clear. My 1993 968 coupe was rotted out under the battery when I bought it in 1999 with 77k miles. I did use a piece of fiberglass fabric to fix the problem but it was soaked in Wurth Rust Guard paint instead of the usual fiberglass resin. The fix has been perfect ever since 1999. This is a neat technique that could help a lot of 924/944/968 owners.



I'd really like someone to loan me a 968 for a weekend so that I can do the work to his/her car and write it up. I'm in the Washington, DC area and would actually prefer to do the work at my house in the Blue Ridge Mountains. (That's where I have a garage.) Would anyone like to have this work done to your car and have it written up in Excellence? I can't promise Excellence will publish it, of course, but all my other stuff made it in.

Bob, that's a real generous offer. "Unfortunately" my battery tray is fine, otherwise I'd be there in a heartbeat for a fix. The Blue Ridge is some of the nicest scenic driving anywhere. I hope someone's able to take you up on the offer.

Bob, after a very heavy rain yesterday which had me seeing water literally running down the side panel of the passenger foot well as well as streaming from the bottom edge of the glove box, I'll be pulling my battery - again - to do a much more intensive examination. At this point, I'm really hoping that I'll find corrosion so that I can bring an end to this once and for all. Here's hoping...

Back to Chazmink's leak.... check the ROOF DRAINS for the sunroof - you have to remove the panel. What is common on 944/951's is a plugged sunroof drain - and water ends up getting in from somewhere near the "B" pillar, pooling under the seats and the lowest part of the car - the footwells. Do a "search" over on Rennlist forums and you should get lots of hits.



If the leak is on the PS up front, it's probably battery box related. On the DS, it's usually the sunroof drains unless it is getting into the instrument panel area which is usually one of the big harness plugs. Pop the hood open and look to the right side of the fuse box - close to the fan motor shroud and you'll find a large rubber plug with a main harness. I had a minor leak there on my 951S - a little clear silicone solved that one.

Anchorman...

I had a leak like that in a 944. I couldn't find the source, or corrosion, but i took out the battery, cleaned up the area, and sprayed in a liquid rubber undercoating substance i picked up at PEP boys. Where ever the crack was, it was filled and has been well nowfor over a year.

Thanks - I think this is going to be a Monday project.

Just discovered the REAR  "passenger " side  foot-well is completely soaked  !   The plastic segments / pillar, and carpet running down from the roof are all bone dry, all the way from the top to the bottom, so the soaked area is limited to only the base floor space .  Its been raining a lot here, and I do a lot of freeway driving, is there anything under the car , in that particular area which might cause water to be kicked up, permeate through and soak that small segment of floor space or is it likely a roof drain tube got plugged right at its bottom end somehow and the water has no place to go but underneath the carpet ?  Assuming that's the proximity of where where the drain tubes lead to...

likely a drain tube unseated and is dumping it into the passenger area.
