Some GM "W" body cars are equipped with a HVAC air filter. This filter is at the base of the windshield on the passenger side under the hood. Look up how to replace this filter for more info. The problem most often seems to be the weatherstrip above the filter becoming dislodged when the filter is changed. Go through the filter replacement procedure and reinstall the weatherstrip. When reinstalling add a bead of black RTV silicone or weatherstrip adhesive to the channel that attaches it to the car. Then press that channel closed with your fingers. It is reinforced with metal so it should keep it's shape once you press it. Reinstall the weatherstrip to the metal seam above the filter and carefully reinstall the valence. If you're worried about the weatherstrip wait to reinstall the valence for an hour or so. I've been told all "W" body GM cars have this same problem, so all 1997 through 2004 Buick Regals (mine is a 2001) and many other GMs have this problem. MY 2001 Regal would get 1-2 inches of water on the passenger side floorboard after a rain. There are three things that can be done to prevent this and all three are quite easily accomplished. As stated above, there is a water diverter weatherstrip above the filter that can become dislodged. Mine was out of place even though the filter had never been changed. I used the RTV method to glue this weather strip back in place. I also made a cover out of an old plastic 1 gallon antifreeze jug by cutting the ends off and then splitting it down the middle and doubling it to cover the filter but still remain above it so that air is not blocked. Once you pull the coweling, which is very easy to do with one plastic screw like fastener and two plastic "rivets" that you just pull out with needle nose plyers, you'll see what needs to be done. Speaking of the coweling, lastely I put a bead of RTV between the coweling and the windshield before puting it back on.
So for one tube of RTV, one old plastic jug, one hour of time using a pair of pliars and a knife I have fixed what had been a real PIA water leak. EASY!
