Default Leak issue

I"m sure this is not the first post about the infamous '95 drain leak issue. I have searched for a hile online and haven't been able to find anyone who has a solution.

I have a '95 coupe and a leak issue that leaves water soaked into the passenger side carpeting. It is not the windshield seal or anything along the top of the door glass. When the water rolls off of the windshield into the drain (below the wipers),the water travels from there down through to the, what I call the flappy udder plug, down below. Apparently the plug had frozen up once, backed up and has not been right since. The water finds its way back up a bit, then comes into the fresh air vent on the passenger side and soaks the carpet.

One person suggested cutting the bottom of the plug, claiming he has not had any more problems. I'd prefer not to do that to keep dirt from getting back up inside of the blower motor housing.

Any definite "correct" fixes???

I had a similar issue with my 86. My problem was the windshield was changed out and the molding that goes down the side is in 2 pieces. Well, both pieces have to be sealed or water seeps down the pillar post reveal on the inside and gets the carpet wet and it was doing it on both sides. I was just wondering if you have had your windshield replaced recently?

Nope...The windshield isn't the issue. If I pour water into the drain without touching the windshield, the water gets in through the fresh air vent & soaks the carpet. If you happen upon anyone who knows a remedy, it would be greatly appreciated. Thanks for the response anyway.

On my way to work today driving my 92 and the windows were fogging up bad and the defroster wasn’t doing the trick. I would wipe them down with my jacket and it was greasy.

Tonight when I got home same deal. I opened the passenger side door and saw wet carpet and something dripping from under the dash. I put my hand in it and it was clear and a little greasy.

Just down I took a flashlight to it and it is green, the whole floorboard was wet. Right now I have soaked it up and have fans blowing in there.

I assume this is the antifreeze? I traced the lines out and don’t see any leaks in the engine compartment.

What am I dealing with here?

I know this is a stupid question but is this highly critical? I just sold my daily driver and am between cars. If I drive to work and dont use the heater will it be okay for a week or so as long as the fluid level is ok?

It will still leak unless you bypass your heater core. Just disconnect the heater hoses from the core and loop a peice of hose between the hose coming from the engine. This will do, but your defroster is not going to work very well. [8D]

One of, if not the biggest, pains in the rear associated with these cars.

Condensor drain could be plugged with leaf bits and other jam. Sometimes mold will build up also and plug the drain hole.
