i HAVE WATER BUILDING UP ON MY FLOOR FROM THE RAIN, HOW DO I FIND OUT WHERE THIS IS COMING FROM AND HOW DO I FIX IT, ANY IDEAS?????MY CAR IS A 2000 PONTIAC BONNEVILL SLE

Got a sunroof? If so, the drain channels that run down the A-pillar'* might be clogged. Otherwise, check your door seals.

Joe, welcome from Alaska! Please put your year and trim level (SE, SLE, SSE, SSEi, GXP) in your signature.

Do you have the sunroof? Where EXACTLY is the water?

Welcome, Joe! Randman also gives good advice on leaking seals here:

Or the bottom edge of the rear window seal, where the rubber meets the glass. Silicone caulking will beat that.

Defective butyl seals on the water deflectors internal to the doors is a good possibility. Several members, myself included have experienced probs with water leaking by the water deflectors and wetting the floors.

if you dont have a moonroof.......bet 99% that it is the door seals

im having the same problem.. anyone have a write up on how to fix the seals

2000 SE

ummm. see above....

That was the problem on mine. If you looked at the seal where it meets the B pillar at the top, you could actually see through to the interior of the car.

I solved it by getting a section of weatherstrip from a scrap yard, same colour as my interrior. I then removed the entire seal and cleaned the gluing surfaces on the strip and the body where it meets and used GM weatherstrip adhesive to glue it back. I ended up adding almost 2 inches of weatherstrip to each door in order for the seal to actually fit the contour!!!!

No leaks at all now

Cheers,
