#72 of 81 Wet trunk and back floor board 96 Grand Am
Nov 28, 2009 (4:12 pm)
I too have wet trunk and floor board back drivers side with a puddle. After investigating where the water could possibly be coming from I discovered the spoiler was dripping water. I have taken spoiler off and will seal it. Has anyone also had this problem???

I bought a 2003 Pontiac Grand AM - 4 door - in 2007 and it has leaked almost from day one. I have gotten no assistance from the dealership. They told me that they don't work on doors or windows. The water appears to be coming in right where the release latch is for the hood. I can see the water when I open the door. It also appears that water has gotten into the fuse box panel and it appears to also be minimally wet on the inside. If I stick a flat-head screwdriver in the joint and lift it back a little, Ican also see water where the dashboard meets the windshield area right above the fuse panel (hopefully this gives enough reference points so that you can tell where in the car I am talking about). I put silicone all around the windshield and this didn't help. I then sealed all around the door and this didn't help either. I also sealed around the area of the door where there is a hoze leading into the side of the car (near the area of the hood release). This hasn't helped either. It does not leak on the passenger side or the trunk just the driver side. The leak has gotten progressively worse to the point where now the entire left side of the car is wet, front and back and the windows are fogged up and sweating from the inside from all the moisture. The smell is also horrible. I put down several towels and it dries out a little bit but if it rains (even a little bit) it is soaking wet again. I cannot afford another car but this problem is driving me crazy. I have standing water in my car EVERY time it rains. Any suggestions or correcting this problem? PLEASE HELP!!

If you are having wet floor problems and you have a sunroof, it is very likely this could be the cause. If the water is on the outer edge of the floorboard (nearest the door) and just under the edge of the dash (either side, driver or passenger) check this solution.
Open the sunroof and look all the way to the front and in the corners. You should see a pencil sized hole for drainage. This hole leads to a tube that drains down the A-pillar (the front posts on both sides of the windshield) and out between the door hinges (on a 2002 Grand Am). If you see debris in front of the hole clean it out. Now pour about a 1/4 of a cup of water down next to the drain hole and watch for it to come out the hole between the door hinges. Make sure both sides are clear. If it doesn't drain and you can't see any debris try blowing it out with an air hose or use a straw and your mouth if you're desperate.
How would this get the floor wet instead of the seat you ask? Your sunroof is designed to deal with water that gets past the seal. Believe it or not, it is not designed water tight. There is a small drain pan that holds that water until it gets drained. If it goes over the edge it gets into your headliner which has a plastic underlayer and (depending on the angle that your vehicle is parked) it runs out the front corner of the headliner where it is channeled by the A-pillar cover down to the top of the dash. It runs down beside the dash into the floor. If you are parking on a steep incline, I suppose you could get water in a different location.
Hope this helps! Oh, I almost forgot. Check those drains regularly!
#75 of 81 The thing about Grand Ams.
May 28, 2011 (10:33 am)
Now into my second Grand Am (1994 SE) I've torn the thing apart and have found many problems No matter the year of the car ever person that I've spoke to that has owned one has had leaks. First off the car is one of the cheapest cars that you will find on the market. I got my second one in a trade. The first one that I owned was a 1992 four door base model with the 3.1 v6. Boy did it leak!!! It was more of a starter car into the world of Grand Am problems for me than anything. The first leak I found on the 94 was on the passenger side going directly into the floorboard. Which for those of you that do not know your ECM/brain of your car is mounted on the firewall inside the car there. Which mine got brain washed (pun intended) If you take off your windshield wipers and the plastic shroud covering the base of your windshield and look to your passenger side you will see a plastic flap that is directly behind the blower fan which is suppose to open and close as you turn on and off your air condition. Once that flap opens it is a direct shot into your floorboard. They put no after thought into the fact that if the flap ever wore out the car would flood. Do not wast your time going to the dealership because they are useless. If their computer can not tell them where the problem is and how to fix it then their useless. Unfortunately there are some thing that has to be done by them like reprogramming the ECM/brain if it gets wet and has to be replaced. Back to the problem. The best thing to do is to reseal the base of the plastic case that the flap is attached to. Forgot the technical name of the part. (work with me people) Be careful because there are screws near the firewall that have to be removed as well as the screws that you can see before you remove the item. It is also glued so if it will not come of easy and the plastic flap is okay the just hit the base of it with some silicone and remember to clean the area good so as to have a good seal form with the silicone. I will post more later. Good luck...

I believe I found the culprit (in my 1986 Grand Am anyway). I just bought the car about two weeks ago and it is in really good shape.
I noticed this leaking you all are referring to almost at once.
Today, it was raining and I had already pulled up the rug and padding on the front floor boards the other day. I noticed water running to the front from underneath the front seats through a channel that seemed to be there under them coming from the rear of the car.
I opened up the trunk lid and the passenger front corner of the trunk was wet. At each corner of the upper part where the gasket sits of the trunk lid GM, for some reason, put a channel under the corner of the back window going somewhere. It seemed to me that it was running down the floor board to the front floor board of the car. I caulked it shut and will do a water test tomorrow.

I have found that grand am's from the mid 90's have a firewall defect. The firewall rusts through, letting in the water that rolls down your windshield. It's most certainly a GM defect, A firewall should never rust through.

#81 of 81 Water Leaks Grand Am's
Aug 05, 2013 (10:54 am)
I have had such problems trying to locate and fix the water leaks on my 1995 Grand Am, that I have come up with my own solution....buy a tarp for around 12 bucks and cover it up when it looks like it might rain or rain is forecast. Other than taking out the carpeting and seats and a whole lot of other stuff that is just too much trouble to do to fix it. When I can afford to I'm getting rid of this mechanical misery...it's more trouble than it's worth!
