#26 of 48 Water Leak by appjej123 Apr 25, 2007 (4:47 am)
That is awful! They KNOW it's a design flaw. It's been happening since the 90's! Mine is a 2000. I had to have my windshield replaced due to a crack and I'm hoping that since I told them and asked them to that they added silicone or something to keep the seal.

Replying to: cobbler63 (Apr 22, 2007 10:49 am) I had a similar problem, it was the tail fin silicone around the bolts. There are six nuts attaching the fin to the trunk lid (bolts are embedded in fin). The silicone around the bolts had deteriated and was allowing water in. I cleaned up the area, apply a health layer of black silicone and no more leak. Hope that helps.   My problem with leaks is when I run the AC. I it hasn't rained in days and yesterday I was blasting the AC on a long ride and water starting pouring out of the passenger side floor vents after an hour of running it. It has to be the AC somehow I'm just not familiar enough with where the water run off from the AC is at.

I have a major water leak in my 2004 grand prix. It first happened around 2005 when it rained during hurricane Katrina. I didn't really think anything of it. Thought maybe the water in the backseat could have wasted because we had water in the cooler for our road trip when we were getting out of town.      Well, we moved to Oklahoma, and for this year it has been very rainy and stormy. Water has been getting in the car nonstop. I finally decided I had enough when water was stagnant on the passenger rear floor board and took it to the shop (pontiac dealership)last week. My insurance covered it because they said it could be water damaged.      So the car sat up there 10 days. No solution. No problem. No one knew what was wrong. The insurance decided to replace the carpet that was molded by the rains without knowing what was wrong. At this point, I became really upset. Covering up the problem without fixing it. I also forgot to mention that water had gotten into the car 2 months prior during a heavy rain and knocked the a/c out. The a/c was fully functioning fine until that night. Well, the insurance decided it was not the water that knocked it out, it was a mechanical issue and my warranty covered it. So back to the story. I called the insurance and went off on them asking them how can give an estimate, release the car and try to cover up the problem without knowing the cause. This was 2 days before I picked up my car. They said they needed to see if they could find out what the problem was first before they could do anything else.        I decided when Thursday rolled around, I would just pick it up. It better be dry and if it happened again, insurance was going to pay. I was going to find someone that could diagnose the problem. There was still no resolution to this ongoing issue. Thusday was accompanied by a heavy rain. Friday rolls around. I am at work at 6:00 PM. Mind you it is sunny, and nice. I haven't felt the carpet since the rain, so I decided to. Front driver side. Dry. Front passenger side. Dry. Back driver side. Dry. Back passenger side. Wet. Wait a minute? Wet....So the water has something to do with something near rear passenger that is causing water to build up in the car. I called the insurance back upset. I told them that water is coming in the car still, and they need to fix this problem. They are obviously missing something. Well, the guy who handles my claims is off. Great. He won't be in until Monday. I told them well, I need this fixed now. I was advised I can take my car to a shop and be reimbursed for any out of pocket expenses. So I will take the car in immediately as soon as a shop opens while this is fresh. I also started researching on the internet to see if there are people that have this problem and low and behold....A lot of people seem to be having a problem with leaks. I was really surprised because it was a shot in the dark. I just want to know if anyone knows what is causing the water to first enter the rear passenger side? What could be causing this issue where water is getting into my car? Replies to this message: netman1 (Dec 25, 2007 12:31 pm) dtrombley (Dec 26, 2007 5:57 am)
#30 of 48 Water Leak by nategrey Jul 24, 2007 (10:28 am)
I have a 1998 pontiac grand prix gtp coupe and my passenger side floor gets flooded everytime it rains.   Temporary solutions seem to be that when I park the car DOWNHILL, water doesn't seem to get into the passenger side floor. When parking straight or even uphill, that's when the water starts coming in.   I'm going to try some of the suggestions on this forum to see if I can fix it completely.

Replying to: nategrey (Jul 24, 2007 10:28 am) The body shop finally found out what was wrong with the car. They said the seal on the windshield was bumpy and was letting water in. They also said there was a loose cowl, which was diverting water into the car. It was a good soaking rain the day after I picked it up, and I checked the car. No leaks. Clean as a whistle. I am very happy this was finally solved. They had the car for almost two weeks trying to figure out what was wrong with it. I was so worried it would not be solved. I would suggest looking to see if there is a problem with the cowl which probably has something to do with the majority of all grand prix leaks. I saw there was a recall about it on pontiac website. Also try looking at the windshield to make sure it is sealed all the way. These problems could be an issue since your leak is coming in the same side mine was.
#32 of 48 WATER LEAK by bigskidogg Aug 09, 2007 (4:43 am)
My 2000 gran prix has been leaking water in the front passenger side also, i fixed the rubber seal as stated in another post and this solved the rain problem but now the air conditioner is leaking into the same area just as bad as when it rains, i know its the a/c because it leaked on a sunny hot day with no rain, i read of a fix on an a/c drain line in another message, does someone know the exact way to unplug the line? any help is greatly appreciated.

Replying to: brybry (Dec 14, 2006 10:02 am) This worked for me but I would add. You might want to go to Auto Zone and buy some 5/16" nylon rivets, 961-060 by Dorman before you pry them out, because they are worthless after you pry them out. Also there is a another cap on my 2001 with a flat line that screws out which is reusable. It's also advisable to pry the rivets out from under the hood so you don't damage your windshield, I used a nail puller.

Replying to: henriejo (Jul 13, 2007 11:58 pm) I am having the same problem. Did you ever isolate the cause of your leak on the back passenger floorboard? Replies to this message: dtrombley (Dec 26, 2007 5:57 am)
