Default Water leak in passenger floor board front!

Hi guys! I have read all the water leak problems I could find on the board, but I have not found anything quite like the problem I have. My Bonneville '97 SSE is leaking rain water in the front passenger floor board. I have tightened up the weather stripping by using silicone glue, but I still have a problem. It seems to happen when we get a hard rain. The leak appears to be hitting in the middle of the floor board cover. I can't believe that, but its true. Any suggestion will be appreciated, (that apply to fixing the leak!) A couple of days ago, water filled the floor board. Obviously I missed something. The car is green. I like it a lot. Do you think the water is coming in around the weather stripping still?

LOL
Help please.

I think you need to look around the cowl area, where the fresh air intake is. This is the vent area near your windshield wipers. I'd take an amount of water in a pitcher, have someone pour it down the windshield on each side, while you are under the dash to check for any leaks. Also, does the car have a moonroof? That could also be a source, but you would normally have water in the headliner, and it would be noticeable.

Well if it is leaking there, what can I do about it? I covered it with plastic this afternoon. It looks like rain outside now.

Thanks.

I didn't say I knew how to fix it. I'm just trying to help you find it!

Seriously, it should have a drain, or a path for it to drain. If it'* plugged up with debris, then the water just stands, or finds an alternate path if it backs up. I haven't looked how it is on a Bonneville, and I don't have my FSM yet. Someone here should chime in any minute...

Thanks for the link. It was very helpful. I did find a hole that had worn in the plastic shroud over the passenger side of the car near the clean air inlet. I am going to hit the area with a bunch of air to clean it out. Maybe that will help. I am not into disassembly though. I still have the area covered so I can see if water is able to get in or not. The hose idea is the next step if this does not work. I really hate this car is sitting out in the rain. We have been looking for a new home with lots of garage space, but we haven't had any luck yet.

Thanks.

Turbo...there is another person in the 00 forum fighting a water leak. Disassembly sounds like a big project, it really isn't and it is the absolute best way to find the actual location of the leak. With Jr'* thread and knowing which leak you are after..you could clear this up quick.

Thanks I checked the 2000 board. That Dude took the entire inside of his car apart. I think I have isolated the leak. I am going to check it out further to make sure. Wow I know these leaks are pesky....but wow!

Thanks for the help guys.
