Replying to: 93grandamsev6 (Jun 05, 2007 12:22 pm) I have a 1995 red pontiac grand am GT, 4 door... got in march 2004, had 120k miles on it. not too bad for the age I guess. it had one owner prior to me and it looked as if the previous owner took good care of the car. The exterior is in great condition and so is the interior (except for the driver and passenger side floor). I have a leak on the driver side floor, this has been going on for over a year now. I've taken it to several mechanics, paid all sorts of money and it's STILL not fixed. Finally I just got fed up with pulling money out of my a$$ and it not doing any good. Mechanically the car is great and I have NEVER broke down... the car now has 165k on it. I try to take real good care of the car, regular oil changes/maintanence..etc. Truth is I HATE that car right now, I HATE IT SOOOO BAD! I hate when I spend lots of $ for something to be fixed and it's not fixed. I'd pay any amount of money to just get it fixed! well last night it was raining hard... I KNEW that this morning I would walk to my car, open the door and see a puddle on the driver side floor... YAY! no shop vac to suck it up so I had to keep my feet out of the water so it wouldn't soak into my shoes.. and of course I needed to be able to use the brake/gas. YAY! (sarcasm) WELL I found out today not only is my driver side filled with water. but after reading everyone's post here I decided to investigate. I lifted up my passenger side floor mat and it's a little wet as well. NOW I remember checking it before and it was never wet, so obviously the problem is getting worse. Before I left work today I decided to pop the hood as well and check my oil/fluids and all that. I popped the trunk, went to grab my paper towels and they were soaking wet! that's a first! SO NOW my FREAKING TRUNK IS LEAKING! WTF?! ya know?! I hate this POS and never again will I buy a grand am just because of all the forums I have read about them. NOT JUST THIS FORUM, but I've searched online and looked at many other forums, grand am's are notorious for leaking in these area's. (mostly the driver side floor) and yes I know my car is 12 years old... (actually 13 cuz it came out at the end of 94 but whatever). so I don't expect the car to act like a brand new 2007 ford mustang or anything like that. Right now the car runs fine and I'd gladly race anyone in it if I had to.  LOL the water leak has got to stop though, it's disgusting smelling. someone told me to get some baking soda and put it in there, it's supposed to suck up the smell.... IT BETTER! It's been well over a year and it's annoying. only when it rains real hard is when it leaks. although even when it's not raining, the floor is damp. (yep, there's water under there hanging out having a party, waiting for me.. I know). I am dreading even seeing what all is under the carpet. YUK. Anyways this weekend if I'm able I'm going to have a buddy of mine check it out. it sounds like the water is coming through these "weep holes" you're talking about. I sure hope I can get this fixed and move on. as for the trunk leak, hell if I know. who knows. I've never had any problems with it til now. maybe a seal somewhere near the tail lights? Anyways, glad to be a part of this forum, glad we can all vent to each other about our grand am problems.  -Nikki p.s. think it's time for me to get that 2007 ford mustang I've been wanting so bad. hate car payments like the next guy but after all the money I've put into the car, mis well get a stang instead of having this POS grand am nickel and dime my a$$.

I had many of the same leaks described in other posts. This car has smelled mildewy for years, but only in the last 2 years did we start noticing puddles. We thought it was just the Louisiana humidity for the first 15 years, but it is becoming clear, that this car was just not seaworthy, and probably had some small leaks almost since it was new that we did not notice because the carpet covered them. I wonder if all cars have minor leaks lurking under the carpet, or if Grand Ams have some special problem: 1. Trunk leak. After a somebody bumped into me at a stop light, the trunk started collecting water. I did not correlate it to that at the time, but this jarred one of the rubber washers ( or seal/grommet) loose on one of the screws holding the taillight assembly. I re-sealed with some RTV silicone sealant and it has been dry since. 2. I was collecting water in front of the rear seat on the right side. (It smelled like a cat had left a liquid gift there, and I thought that was what it was for a while, but it was just water festering under the rubber-backed floor mat.) I took off the plastic trim and peeled back the carpet in that area and put a hose on the top to pour water on that side, and it was definitely leaking in the door area. I tried to seal around the weatherstrip with silicone sealant and then with weatherstrip adhesive (3m 8011). There was still some dripping so I looked closer and noted water was dripping in from the center pillar of my 4 door. On closer inspection, I saw a small crack in the sheet metal seam sealer under the exterior drip edge trim, so I bought some new seam sealer and patched it up. 3. Things were better for several months, but then I noticed that dreaded smell again. Then I realized the carpet was wet also on the driver side and some in front of the front seats. I decided to remove the carpet until I could get this under control. If necessary, I was considering drilling holes in the floor to let the water drain out. I went through several stages around the doors and ultimately I replaced the weatherstrips on 3 of the 4 doors and re-did the seam seal. The weatherstrip needed careful application of weatherstrip adhesive 8011 on the top half of the door on the external side. It is not supposed to need that, but I needed it to stop the leaks. I think the adhesive would have worked without the new weatherstrip. I applied new seam sealer on the seams on both sides at the top of the pillar between the doors. I did more careful surface prep this time and completed the job with some touchup paint to protect the sealer. I should have primed the bare metal before applying seam sealer, but I hope what I did do will hold. This dried up the leaks around the doors. 4. Much to my chagrin, I was taking on more water than ever, though. With the carpet removed I was able to see it was pretty clearly coming from the firewall area, which I never bothered to test with the hose. There are channels in the flooring leading to the back seats, so this was probably the major source of the problem all along, although I am still glad I fixed the leaks in the door area. The interior of the firewall looks very difficult to access so I investigated the external side. I removed the wipers and the plastic cowl pieces. On this car, it does not look like the issue is drain holes on the sides plugged. There is a seam about a third of the way up the firewall from the bottom and applying water there with a hose will show the leak in the interior. The main drain for the cowl area seems to be a channel around the HVAC system intake and the blower. This was blocked with leaves. I removed the duct around the blower, and also noticed a pile of mildewy leaves bunched at the evaporator, and cleaned out all the leaves. I am hopeful this will clear up the recent loss of air conditioning capacity on hot days. I am in the middle of this part, but my plan is to go to town with some black roofing caulk on all the sheet metal seams on the firewall and to put some plastic screen material to block the leaves out of the air intake and cowl area. Finally, I will get some black RTV to seal off between the windshield and the plastic cowl, also for the leaves. This has been a ridiculous amount of work, but after all this, I just have to get it stopped. Hope this is entertaining if not helpful. |

I have a 2002 Grand Am and it seem that the only time I have water is when I park on a little bit of an incline. I only get it on the passenger side of the car though. I'll have my boyfriend check to see if anything is clogged...didn't think about that. I'm more concerned that mine is going to leave me stranded somewhere again! Have any of you posted complaints with the National Highway Saftey Admin to see if you can get them to force GM to do a recall? |

I have a 95 Grand Am, floor was wet everywhere. Found that the Plenum or area under the cowl has two drains on either side that dump water onto a portion of the fire wall that meets up with the front wheel well. There is a Seam there and it collects water, causing it to rust out on both sides of the car. Pulling out the computer on the passenger side (beneath glove box), and behind the carpet an sound materials, there was a 2" wide by 12" long hole extending towards the centre of the car and under the heater. Also, on the drivers side, same spot between E-brake and brake peddle, a 2" hole. Since I only intend on keeping car for a few more years, i gutted it, dumped the soaked under pad, filled the holes with spray foam, coated the foam with undercoat in the engine compartment and drilled a few drain holes in the floor pan, in each channel. Got some cheap rubber under pad and put the carpet back. Problem solved. What a pain in the butt though. I work in one of GM's assembly plants and am happy to say that today, the firewall and wheel well on the inside of the vehicle are one stamped piece with no seem. i guess they figured it was a problem.

Replying to: mikey001 (Nov 21, 2007 7:14 pm) dang that does sound like a pain in the butt. me and my boyfriends uncle have been working on finding the leak for a while now. we spent 9 hours on the car last sunday. We'll see if it worked after we get a good rain. Right now I got other issues besides water in my car. First, my car started smoking one day when I arrived at work so I popped the hood and a good bit of smoke was coming out and a fluid was leaking onto the ground. I believe it's the power steering going out or something because my car is making a horrible loud noise when turning the steering wheel and it's getting progressively worse and hard to turn. bad news is no one is open because it's near thanksgiving so I gotta wait til maybe black friday and hope some mechanic can get me in short notice/without an appointment and hopefully fix it without it costing me too much money. All I do is keep putting money into this 95 POS grand am. GETS ANNOYING! after I get it fixed I'm selling it! right now I'm waiting on the ford dealership to call me back cuz I want a damn mustang  , so I'm in the process of spending money to buy a newer car. LOL so happy thanksgiving to myself I guess. LOL stupid car problems. I wish I was a mechanic then I could fix my own shit.

Replying to: pos95ga (Oct 26, 2007 2:22 pm) Bulletin No.: 73-10-68 Date: April, 1998 Subject: Water Leaking into Passenger Compartment (Apply RTV Silicone Sealer to Top Vent Grille Assembly) Models: 1996-98 Buick Skylark 1996-98 Oldsmobile Achieva 1996-98 Pontiac Grand Am Condition Some owners may comment on water leaking into the passenger front floor area. Cause Condition may be due to poor adhesion of the top vent grille assembly to the windshield. The existing seal tape can separate from the glass or the grill above the A/C air intake canister and allow water to overflow into the passenger front floor area. Correction Remove the top vent grille assembly. Clean the grille assembly and the surface of contact on the windshield of all sealing tape and adhesive residue. Apply a bead of RTV Clear Silicone Sealer from SM(R), Part # 08662, or equivalent, to the underside of the top vent grille assembly where the old seal tape was removed. Reinstall the grille. Wipe excess RTV Sealer horizontally across sealing area to achieve a smooth finish.
