I know of two Bonnevilles that leak into the back seat and floor when it rains. Is this a common problem with this late 90s cars

Don A has an excellent answer, but if you have a sunroof, that is more likely the reason. The pipe runs down between the door pillar and the windshield and there is often a join there which can part. Be careful with compressed air as it can blow joints apart.

I don't think it can make from the trunk to the back floor.A better bet would be a leak with the weatherstripping at the back or bottom of the driver's door.

Get your heater core checked. May be leaking.

Dry the car out then get inside the car while someone to hose the card the right hand side of the car so you can observe where the water is entering into the car.

On a dry day take a garden hose and shoot water in any area that could leak and check and see if there is water in any of those areas. Also check under the car to see if there are holes or cracks that could leak. A rust spot will sometimes leak as well.

I had the same problem with a 1994 Taurus. Within the front fender was 10 years of pine needles and leaves blocking the drain backing the water up in and over the fire wall and into the front passenger seat floor.
I took a LONG pair of needle nose pliers threw the passenger side door, and was able to remove enough debree. After pulling out out about 5 fist full's of yuck, 1 gallon a water that was stuck some where poured out flushing out the drain. I did the same on the drivers side. After that I had no problems with floods. I hope this helps. If not check your back door weather stripping if you have one. I have heard water leaking behind the passengers seatbelt and onto the floor from under the seat. Got to love Florida's rain season(s)

Door seal at the top of door?

check your door seals, have someone sit in car while you spray door with hose at around the door perimeter, common poor weather stripping on doors... may need to replace or refit stripping....

hi it sounds like your rear window is leaking. it must be removed then re sealed to stop the leak

sounds like the weather stripping around the door is bad or is torn
