I had the same problem. I bought the stupid car and a month later it was flash flooding on the passenger side floor. You could actually see a steam pouring in! I took it to the chevy dealership and they told me to come back when their "WATER SPECIALIST" was in later that week! This happens so much that there's a damn water specialist!!!! i was pissed!

Bought 2000 Impala from out-of-town seller in Apr 2008. Since then, have had problems:

air bag lights come on (learned how to reset it every month when light pops on again-after purchasing 150 bux gm factory manuals), it won't start on occasion, turn signals stop working periodically.

The one problem I am writing about that I acually FIXED was the killer water leak I had after 2 days of a downpour-I had the car 3 months. My wife called me from her job saying 'the pass. side floorboard is full of water!' She did not lie. The water had escaped the holding pond of the passenger floorboard and was filling up the cavity under the front passenger seat. So I got my razor knife from the work truck I had driven and cut out a "flap" so I could access the removable black rubber drain plugs in

the passenger floorboard. Did the same under the passenger seat, where, surprise- the SDM module (read airbag) is conveniently located-water cooled I guess. Anyway, I stopped the water leak completely by silicone caulkng between the windshield and the black plastic cowling on the passenger side. My leak was not due to debris clogging up the cabin air filter under the pass. side cowling.Taurus my favorite. KarlF

What you have is a leak at the hood seal. The water is running down the weather channels as it's supposed to but the seal at the hood nearest the windshield is no longer blocking the water from going over the lip. The water makes its way past the seal down through your cabin air filter, down through the heater motor and onto the floor. This can also create heater motor shorts and you will lose that blower if the water goes the wrong way after the cabin air filter. If you can replace the seal do that, but you may be able to get by simply by using an adhesive and making sure that seal is good at the hood. Good luck with the fix!

I noticed I had a leak somewhere around the dash on the passengers side after a rain or if I ran the car through the car wash. After about the third time of having to dry the smelly carpet, I figured I had a bad seal on the windshield that would have to be replaced. When I had stopped at my local Texaco/Havoline Express Lube (I just love those guys) to get my oil changed, I ask the guy there if he knew anybody good in town that could do this. He ask me why and I told him what was going on. He popped the cowling from the glass and there is a cabin air filter box under there. He removed the cover and there was leaves and stuff all clumped up on top of, in and around the cover. He cleaned all the debris away and put the thing back together. That solved my problem...I haven't had another leak since. He said when you get that area plugged up the water can't drain properly and it ends up going INTO the car. Hope this helps.

I was parked in front of my girlfriends house there was no leak. We went in for about 2 hours or so and it had been raining. We came back out, and I saw that the passenger side floor was flooded ankle deep. Could not find the source of leak. Checked the windows and door and couldn't find out where the water had come from. I dried out the water with a towel and drove to a friends house. We were gone about another hour and came back to find the passenger side floor flooded again! There was some traces of water under the dash board so it could have been leaking from there. Im gonna take it to the Chevy service department to report the leak and see if they can fix it. If i find out i will post a solution. If anyone had had the same problem and solved it please email me with the solution. Thanks.

I found a huge puddle of water filling the passenger compartment floor after a rainstorm and had no idea what happened. It was a significant amount of water and it was only on the passenger side. Luckily there is a plug on the floor under the carpet that you can remove to drain the water out. The padding under the carpet really soaks up some water too, so that had to be squeezed out by hand. It happened a few times before I broke down and had to spend at least $400 to get it fixed - I don't remember the exact amount. They said that they had to deflect the water streaming down from the roof and cowl and the channels inside the door frame to run another way because the water was getting in somewhere behind the glove box. I didn't have a problem after this for two or three years until a couple of weeks ago when I saw a wet spot on the carpet, again on the passenger side, after a rain storm. I have not really been able to get that stale smell out of my car since the original problem, which is very inconvenient.

When it rains, passenger floorboard fills with water. Same as other complaints!

Can barely see it trickling down from behind the dash - but not real sure of the actual spot of the leak.

Where I live it tends to rain when it wants to. And when it does rain, it rains a lot. So I was driving my car down the street and I hit a water puddle and kept on my way to work. When I got there, I reach over to get some paperwork off of the floor on the passenger side and its soaked. I look for a spilled drink or something, but there wasnt anything. I then realized that the whole passenger side floor of the car was soaked. I couldnt believe that so much water came in the car from hitting a puddle. But it has happened numerous times. I have replaced all of the door seals and purposely driven through big puddles on the drivers side to try and duplicate the other side of the car. But the car only seems to leak water in on the passenger side. I also have a 64 Impala, and I have never had any problems with leaking. Why do they make newer cars so much crappier than the old ones. All the fun gadgets arent so fun when you gotta replace stupid sh*t all the time.

Water pours into the passenger front in 3 streams under the dash - ankle deep. Got this dry and then the back right floor was drenched. Wondering if this is windshield - or some drain is disconnected

While broken down at my parents house (transmission went out) the car had an unexplained leak which left standing water on the passenger side floor only! Could find NO source of a leak. Dried the floor out and put in several "Dries Air" containers to absorb moisture. Continued to empty water out of the containers and add more packets of beads as needed. Car was covered, but continued to have moisture although not as much as when first discovered. Thank goodness we were checking on the car while it sat!!! We still are not sure what caused the leak. Any ideas would be appreciated!!!
