Re: 2000 grand prix leaking on drivers side floor board
I have a 99 Grand Prix that had the same problem. There is a rubber gasket that has probably come loose that is under the plastic air inlet grille. This grille is up against the windshield and the wiper go through mine in my 1999. Remove this grille and you should see a water deflector that has come loose. Use some silcone to secure it back in place and that should stop the water problem.

Someone in the car watching for leak, someone outside the car with a hose.. Gently apply water to the door area and person inside looks for the leak... Another possibilty. If the water is comning from under the car it can be a rusted place or a body separaion.. harder to find. It can be comning in from around the windheild seal and running down the interior firewall. This is how a shop would find the leak.. but they would charge you for it..
if its the same set up as my oldsmobile intrigue there is a plug behind the glove box that has a sensor board, my fan quit working all together and I swapped that sensor out and everything worked fine afterwards, does your right side passenger floor board get wet when it rains hard, if so it has shorted part of the sensor out for the high side of the fan.
A water leak under the dash could be the heater leaking near the glove box, or a windshield leak, or sometimes the drain tube for that area has gotten plugged up and needs to be cleared out. Most times a little blast of air pressure will do it.
Hope this helps.
I am guessing that you recently had a windshield replaced. If so they didn't seal it well and it leaks in there. You can go to a glass shop and have it re-sealed or you can buy sealer at most automotive stores and do it yourself.
The other option is that it is leaking in through the air intake between your hood and the windshield. That is the air intake for your heating and air conditioning. There are drains in the line that can get clogged up. If that is the case the best option is to take it to a repair shop.
first, when I read your post I remembered that if the ac drain hose (small hose stub on the engine side of the firewall, usually on the passenger side) gets plugged this can happen. If that doesnt fix it, get a friend to spray with a hose and start looking for where the water is entering the cabin. Leaks are a real pain to find, even for shops, so don't get discouraged if it takes a while to beat this!
