Meldoy, sister! I had the same problem with my '98 GT! Thought it was a crack or leak on windshield. It was the water regulator inside the bottom of the windshield! It just needed to be set back in place. Have someone remove the plastic plate holding your windshield on (Lower). It's rubber and easy to fix. Don't pay someone to do it you can do it yourself grilfriend!! I HOPE this is your solution! I almost know it is!  Marie

I have the same exact problem with my car... i poured water down the vent grills and the water came ou the bottom like its supposed to... now i jus took it to a mechanic and he said they have to take off the whole entire dashboard and do something with the water heater... i do not understand how all this water can come from a water heater? They want to charge me 325$ and id rather get a simple solution and do it myself.

I have a 99 Grand Prix GT and have the same problem. One day after a heavy rain I was driving and when I made a lefthand turn water started gushing from underneath the dash. I could hear it going through the a/c fan motor. The dealership said it was the a/c drain line and charged me to unstop it. Needless to say, it messed up my blower and resistor, which were easy fixes. The car also now has a musty smell. I still have my doubts if this problem is really solved. I never drive it in the rain anymore. I decided to sell it because i'm tired of worrying with it.

The water is leaking between the plastic that sits on the windshield behind the wiper blades. Behind the plastic is a foam gasket that deteriorates and the water runs down into the heater fan motor and overflows onto the floor. Buy a tube of black silicone and run a bead across the plastic where it meets the windshield if you do not want to take the whole thing apart. It was a problem with my wifes car until I took it all apart to find the problem. Okay now. Stan

I tried using some old weather-stripping I had on hand,but still had some leakage.Yesterday I used some clear RTV silicone sealant adhesive,and ran it across most of the windshield area you speak of.It rained cats n dogs today,but I still have a small amount of water seeping in.I dropped the glove box,and can stick my hand out the rubber door behind there,and there was no water standing there,so now I am stumped as to where exactly it is coming in at.I will put more sealant around the edges if it ever stops raining.I just got the car for new teen driver,and seems we have had more trouble than its been worth.The leak fried the blower fan relay (i think),so now the fan only works on #5,but hate to replace it and have it get ruined too!I am worried the water will ruin the wires,radio,etc.Winter is coming and I NEED to resolve this!
Also,how does one clear the things that run from front to back on each side of top of car? I dont know what they are called,but are tiny drain things.I think I heard someone say once that dealership maintenance people cleared theirs with a long pipe-cleaner thing,and ran it the length of the pipe.Just taking wild guesses now...........
Any more help and advice would be appreciated.reply on here or contact me by email if anyone has any words of wisdom Thanks

New ,Used G.P.owner,I have a good idea what causes this,after looking at the way they did that being an contractor and not a mechanic,Under The car the a/c Drain pops out horizontily With that cheap tee down spout,If that down spout is loose or is not there,water would simply travel back onthat plastic nub{which pops out from inside{Walks up the pipe back into the car,I connected a 1/2 plastic pipe to the inside and routed the water drip to a better place , instead washing the dirt of thecarrage.

Hello Stan
I hope you've had some success solving your problem. I recently purchased a 1999 Grand Prix and have not yet experienced any of the "leaking" issues that have been described by you and the others. However, I suspect there may be a similar problem with my vehicle because all of a sudden my heater motor will only operate on #5 (high). Like you, I don't want to replace anything until I know for sure what the problem is. Winter is already in full swing where I live so any help you can provide would be greatly appreciated.
Thanks
JD
