I am new and hope someone can be of assistance. I have a puddle of water standing in the rear floorboard behind the driver seat and I can not find where it is coming from. Seals are dry and it gets wet only when it rains, HELP please, also the ABS anti brake light stays on any suggestions? :( It is a '96 Bonneville SE 4 door, no sun roof. As far as I can tell the heater core works. It did seem a little warm with the A/C, kind of like it needed charged. Around the door appeared dry. I really hope someone can come up with an answer. It has been about a month now and I am still baffled.

Thank you!

I don't know much, but when this happened to my SSE, it had something to do with my heater core not functioning properly... does your heat/ AC work?

EDIT: oh wait, nevermind, I think that'* only if the water is in front of the passenger seat.

Could you put your year and model in your profile? Do you have a sunroof? If so, sometimes the drains plug up. It could be door weather stripping too. Searching will provide some threads with different problems.

Edit - This will give you a starting point.

Before you bury yourself in those threads..... there are 2 high probability places to look first.

There is chrome trim above your front and back doors. It is shaped and acts like a rain gutter. If you look down into it, you may see that areas of the "gutter" have come away from the roof. A 1/16 of an inch is all you need, and water can get in. It will collect down your middle (B) column and accumulate on the floor behind the driver seat. Use some RTV silicone to fill any and all tiny gaps in that gutter.

Next, open your front and back door. Look at the rubber gasket on the door openings. Is it absolutely secured or are there areas where it has pulled away. Particularly look in the upper right corner. The rubber gaskets shrink. Again, your trim will nicely collect the water and deposit it on floor. You can RTV the gasket back or re-lay the rubber. Make sure there is no gap in the rubber at the bottom of the doorway. Also check for any cracks in the black trim around the doorways.

Check these two before you go towards the more esoteric possibilities. People dump their Bonnevilles because they have these exact water problems. They can be solved in 15 minutes to a couple of hours.

Welcome to the Bonneville Club, where not every answer is easy. But many just might be.

Like Charlie said, shrinking door seals are a common problem. The easy fix is to remove the plastic trim that holds the rubber seal in place, and pull the entire seal off. Then, re-apply the seal starting with the center of the seal at the top center of the door opening. The seal will just push back into place. Take care to push the seal into place as far as it will go all around, not allowing any part of the pinch weld to remain exposed. Because the seal will have shrunk over time, the re-installation will result in a gap at the bottom center of the door. Water will not enter the car with a gap at that position, but dust and noise will. So, for a more complete fix, go to a junkyard and remove a seal from a car like yours and cut out a little piece to fill the gap.

Thanks so much, I think it may be fixed. I am waiting for it to dry completly and then I will spray with water and check it out. It looks like suggestions from charliemax & bill buttermore might have been right on. I found two screws loose, one almost out, on the door holding the the gutter on. :P

Thanks a million and sorry I did not put the year and model on. I am new but that is no excuse for not reading the instructions, right?

'96 Bonneville SE 3.8 L V6 Light Blue 4 door luv it even though it is soggy. (did I do this right, suggestions) :?:

Well, I am back and puddle did dry out but it has been raining alot here in Wichita, KS sooo you know what happened-soggy. This is about the fourth time and I am about ready to give up and take it to the dealership, which will probably cost and arm and leg. I have tightened the screws along the gutter and the rubber seal "seems" tight. :(

Ladybug, this should help you:

Your door seals are pulling away in the corners. Even if you can't see it.
