Unhappy 92 sunbird water leak on floor

I have a 92 sunbird and i am getting water leaking onto the driver's side floor and would like to know where the water is coming from
A few friends have similar cars (cavaliers) and are having the same problem The cannot find where the water is coming from either
Your knowledge would help some soggy feet
thank you

First, we have a question. Is it water or is it coolant. It could be either. If it's water and is happenning when the A/C is on, then it's likely that your A/C condensation drain is plugged. If it is coolant leaking, then you have a bad heater core which is very common in those cars.

4 or 5 yrs ago there were a couple, maybe 3 TSB's on windshield sealant, check with a dealer, just maybe they can still pull up the tsb's. Some one on the board may be able to give you the details from alldata. The sealant used could be the water problem you have. However this late in the game you will likely have to cough up the repair bill.

Is the water clear or stained?does it occur only during rain or ac operation?Does the floor get wet if the car is parked or only if driving?Water leaks can be checked by the following procedure.Two people on in the car looking at the suspected leak area the other applies low pressure water stream to the lowest point of the car and slowly works up higher on the car until alerted by the person inside.A horn beep perhaps.Then you know where the water is coming in and you can repair it.Sometimes components of the car will need to be removed to diagnose water leak concerns.I searched for bulletins and found none.

If it is a heater core leak and want a temporary fix until you can afford to get it changed, pour a box of ground black pepper into the radiator. this will plug small holes. Just make sure to change the coolant after you get the heater core fixed.

I just checked the gazillion TSB's in Alldata and the only thing there related to windshields refers to the type of sealer to use when REPLACING the windshield, and some others related to convertibles. Nothing that refers to leak repair.

I still haven't heard weather it's coolant or water yet. We need some more input from the original poster here.

water leak

The water is from rain not the heater core and the vehicle does not have to be moving as I have found water on the carpet after the being parked for the night
The carpet going behind the brake pedal doesn't seem to be wet either
I might try to get a friend to help look using a hose but the temperature outside right now is not going to helpful
Thank you for your insight Mike

These type of leaks are very difficult to find sometimes. My 92 Camaro had one up until I got rid if it. I never could find it. But of course the windshield had been replaced before I purchased it.
Good Luck,
Billy

The water leak is most likely from a shoddy windshield replacement. It could even be so bad as to have caused the pinchweld (depressed area that windshield fits into) to rust badly.
The other possibility is one mentioned earlier. GM had problems with paint bonding issues on several colors. White, silver and silver-blue are the ones that I can remember off the top of my head. There may have been more. When the glass is bonded to the paint but the paint is not bonded to the car, a leak results.
All this is provided that you don't have a sunroof of course.
That's a whole `nuther can of worms...

Windshield: Only other alternative is some clear silicone. I have sealed a few this way. Wipe off excess asap.

Not to be a know it all or anything but...
Never use silicone RTV to seal a leak in the glass areas.
That vinagar smell is the acidic part of RTV. If there is a rust issue behind that moulding, the acids in RTV will make it rust worse. There are non acidic RTV's but they are usually only available through glass shop suppliers.
One should always use urethane based sealants for sealing glass.
