Carpet very wet on drivers side floor

Hey guys, need some help. Every time it rains hard the drivers side floor gets completely soaked. I've opened my door to a puddle of water sitting in the drivers side. Usually about 2 inches of water sitting there. I have no idea where its coming from and dont know what to do. Any help would be appreciated, thanks

They only talk about passenger side not the driver side.

Yeah, I've never seen the deflector problem get the driver's side wet. The deflector problem causes water to pour directly into the blower housing and it leaks out the housing on the inside effectively soaking the passenger side. Since it's your driver's side suffering, I'm sure the deflector is not the problem. Unfortunately, I'm afraid you may have some other problem and I'm not sure which direction to steer you in on this one to help you solve it. :(
 
hopefully you dont have the same problem i do causing water on my driver side carpet. the roof is rotted and rusted away under the rubber seal around the windshield. roof looks perfect till you lift the black seal around the windshield , lotsa rust under there on mine. upside is this gives me a reason to pick up a gtp :D
 
Close the window. JK, had to try and throw a little humor in there. Not sure what would cause the driverside to leak. I have always hear of the pass side. Do you have a sunroof? Headliner wet any? If you have a sun roof, that could be leaking and the water running down the a piller to the floor.
 


i was able to sit in my car and watch the water drip (sometimes stream) right out of the corner of the dash , onto the parking brake pedal then onto the floor.
 
Sounds like a windshield leak. I would pull your a-piller trim off and possibly the driver's sun visor so you can pull the headliner down just a little. You should be able to see the urethane adhesive that glues in the windshield by looking in between the glass and pinchweld from the inside. While keeping an eye on that, have someone run water on the top corner of the glass and watch for leaks all the way down that side.

Sounds like that is the problem and it is running down the a-piller and dripping down by the e-brake pedal. When you find it, you should be able to get a tube of automotive urethane at the parts store and seal it from the inside, then water test again and replace your trim.
 


I just discovered this exact problem in my car this morning. Drivers side is completely drenched. literally looks like someone poured a gallon of water under my floor mat and then put the mat on top. The mat wasnt wet on top and there was no wetness anywhere else that would help point towards a leak. It has been raining since yesterday afternoon. I was also driving for almost 2 hours yesterday in the rain and saw nothing to indicate a leak during my drive home. It also only wet in the very bottom of the floor board where the mat would lay, nothing on any of the "humps" coming up. Im lost on this one. Could definately use some advice.

EDIT: Just saw this thread is in the engine section for some reason. Could this be moved to a more appropriate area?

We have a 2007 Grand Prix and have the same problems. Severe leak on driver's side somewhere high up under the dash. I have removed the cowl panel and everything looks good under there. This thread just ends... did someone find the fix?
 
I know that on mine the windshield was replaced by former owner and not sealed properly. I have to get my windshield re-sealed by a professional. If any of you can hear any wind noise while going fast with the windows rolled up all the way, there is a good chance that it is a bad seal somewhere along the windshield. Also as mentioned above it could be coming in through the sunroof if that seal leaks at all. There are water channels(one on each front corner on mine) that can get clogged. I checked that mine or OK as I dumped some water in each corner and made sure that it drained properly. I know mine is not visible unless watching it run down from inside of the trim and out into the floorboard, but all leak locations may be different. 90% or better chance that it is the windshield leaking or sunroof if you have one.
 
Thanks for the info. But we don't have a sunroof. Of course it could be the windshield leaking, put I removed the pillar cover and can see where the windshield and frame meet and there is no water coming in there that I can see. It remains a real mystery. I can pour water all over the cowling area below the wipers and get no water in.
 


you are not going to be able to see a hairline crack in the windshield gasket material. I would bet that it is coming through the windshield unless you have a major rust issue going on somewhere.
 
Probably right.
So what I'll do (as soon as it quits raining) is pull off the rubber seal around the windshield and try to force some RTV into that space then replace the seal while it is not yet cured. Any recommendation for a sealant other than RTV?
Hopefully that will work, if not I guess the windshield will need to be pulled?
 
Well, I am not sure what sealant to use other than RTV. If that still doesnt work, I would personally pull the headliner and A pillars to make sure that is where it is leaking from. If you want to see where about the leak is and you have an air hose hooked up to a compresser, take soapy water and rub it around on the outside of the seal. Take the air hose and spray it with air all around the windshield or where you think you may have a leak. The air will follow the leaks out and blow bubbles or atleast move it around so that you can see where the leaks are at. And, no, that is not my GTP being clocked. Good luck...
