Hello, I have a passenger car leak. its under the door panel, and makes the passenger floor wet and the rear passenger side wet as well. I am not sure if its coming from were the whipper are or the seal under the door, the panel seems to have water spots on it as well, I pulled the panel off to get the water dry under the carpet on the floor in the passenger. Not sure what the problem but its not that bad in the front passenger but the rear passenger floor seems to be the worst with the wetness. HELP ME, its a 2000 pontiac grand am se2, two door.

I have a 95 Grand Am and my floor was getting wet and my windows fogged on the inside. I was told it was my heater core (which seems to be a problem on the 95 Grand Am) and had it replaced.

For Everyone that has this problem and has a sunroof the water is leaking in from there the are 2 drainage holes that are visable when the sunroof is open the water will back up inside of the car on eitherside depending on which hole is blocked. easy fix is a straw, blow into (gently if you break the tube you have to buy the part an have it installed) pour sum water repeat till u see water clearly roll out, the water should come out under or near the front fenders by the wheels

I have a 94 Grand Am and have been fighting this problem for awhile now. Still no success, but I can give you a money saving tip while you try to diagnose the problem. You MUST determine what kind of water is leaking....rain water or engine water. Engine water will have coolant in it, will smell and have a sweet taste(lol, I know gross). Dont waste your money replacing a heater core unless its engine water thats inside the car. Another thing to consider is if your car is parked on an incline over night...if so the water maybe coming in from the front and running under the carpet into the back seat. Thats whats happening to mine but I cant find where its coming from at the firewall.

Look on the firewall on the drivers side for a rectangular electrical box about 2" x 4", its about 8" below the windshield and about 8" from the inner fender. Buy a tube of weather stripping sealer. Seal around the base of this box, On mine after the sealer I sprayed black rubber under coating over it. This worked for me. It took a year to find the problem. Good Luck.

I agree. I am so glad to have found this forum.. I will add another level to the Pontiac Grand Am water issue.. Mine is 94. I recently got this car, as it was my dad's. Very low mileage, and he kept it very well maintained BUT it sat for quite awhile without being driven (about 6 months and then went through a cold winter in an unheated garage (Northern Wisconsin) .
I have water that now accumulates in the back passenger floor well and on the driver's front side only. Sometimes I have 2 inches in the back seat. I dried it all out, (still not knowing for sure where it is coming from), and with the floors perfectly dry, I drove it for about 2 miles, let it sit in front of my office, (not raining) and when I came back out to go home, it looked like a poured a couple gallons of water in it!
My guy and my mechanic that there is a leak where water is getting in and getting trapped. I will pass these replies onto them BUT how do I explain the two different places that ge t wet.. (Front Driver's and back passenger)?
I would love and greatly apppreciate all the help and suggestions that any has to offer.. I love the car, but I hate letting it just sit and not be used.

Honestly, I think you should take advantage of the Cash For Clunker government program being offered right now (I would think a 94 Grand Am would quality for this deal). The Cash For Clunker deal is sweet and I only wish I wouldn't have let my 95 Pontiac Grand Am go to the Demolition Derby at the County Fair last summer. If I had kept it on the road one more year I could have traded it in at book value PLUS the government would have given me an additional $4,500 on top of that! It's a program they are doing to get older cars off the road and stimulate business at dealerships. If there is anyway you can make a monthly car payment of any sort you should seriously consider this program. Not sure how much longer it's going to be going on for. I can say from experience that once the Pontiac Grand Ams start getting their mystery leaks they can be impossible to fix... I had 3 or 4 mechanics look at mine and none of them could permanently fix it although they tried several things. Basically once they're they're for good! I don't even think Pontiac Grand Ams are being made anymore. I have a 2008 Toyota Camry now and am loving it... it's reliable and more gas efficient and has much higher safety ratings than the ol' Pontiac did. Best of luck!

According to the latest info on the fuel economy site, neither a 4 or 6 cyl 94 Grand Am qualifies under the CARS program since they have combined economy ratings above 18 mpg. I doubt if a 95 would either.
