Thread: Water in Passenger Floorboard [*]

This How To write-up on Water In The Passengers Side Floorboard has been added to the HOW TO section and can be found HERE.

You got my vote for an excellent thread and I will sticky it for now until we can get it to a how to section if needed. Thank you so much for this contribution.

Thanks, looked like the "Known Issues" section was the best place for it at the time, even if it isn't commonly known.

You keep on going, you got more info like that, post it up...

I have made a Word Doc, OpenOffice Doc, and a PDF out of this. When the HowTo section comes on line, we'll get that posted up. Thank you so much Abrasive for your contribution. Looking forward to many others.

For what it's worth, I believe the Buick Regal's did come with a cabin air filter from the factory. I'm sure someone could correct me if I'm wrong. If you do have a cabin air filter, this is even more important because you do not want the filter getting wet. It could cause mold and actually make the air quality worse than no filter at all.

I labeled this as W-Body because this is a very common problem with the Grand Prix, Regal, Impala, Monte Carlo, etc. They all have the same set-up. Why on earth GM didn't just extend the metal flange on down to sheild the entire opening is beyond me. Seems that would have been much more effective and there's plenty of room between them so it wouldn't have hurt airflow any. Probably just a design oversight.

Edited a bit to include more specific model years. This primarily only affects 97-03. Also included some cabin air filter part numbers.

More part numbers.....

Plenum Water Deflector - GM Part #10388810
The three small cowl retainers - GM Part #10053182 (sold each)

THIS sounds like the making of a mod **cough** Abrasive **cough** that could be worth looking into and selling under the shade tree vendors. If its something that can be fixed simply.

I have never had to mess with this so I cant speak to that directly.

I think the problem would be (and maybe why it doesn't extend further) is that people running a cabin air filter would not be able to get to it. If you did make something, it would have to be easily removable to access the filter. Which would mean it would need some sort of seal or gasket where it attaches to the flange anyway. You'd just be trading one problematic part for another one IMO. Using an adhesive to attach the existing deflector will eliminate any problems anyone has with it for good.

BTW... I mentioned using RVT sealer to adhere it with. Another good option is a tube of windshield adhesive. That what mine is stuck on with since I have it readily available. It's black and you can see it in the pics where I pulled it part of the way off. Never use straight silicone on a painted surface. Make sure it is non-acidic silicone, or specially recommended for automotive use, if you do. Regular silicone will eventually cause the paint to peel away where ever it touches and will cause rust.

Another fine piece of information that deserves to be kept around in some form or fashion.

nice write-up. This happened to me last year after a huge rain storm and i got in my car and about **** a brick. I had like 1-2 inches of water on my passenger floorboard.

I have this problem and haven't done anything about it yet cuz now that it just snows its not a problem...now that I know how I definately will....that is when I get my car fixed and can open the hood!!!

Where can i get a 'wiper puller'? They dont look to corroded but I just cant get the wippers off is there any other way to get them off?

You can get them at most automotive parts stores. But in my experience, as I have one, they dont work to well on our cars because its hard to get it under the wiper. I also have a battery terminal puller that works MUCH better which can also be found at most automotive parts stores.

you may have a stupid leaf or debris in your drain like i did =[

Thanks for the detailed write-up. It definitley helped me solve my water problem. You got Rep!
