2002 buick century back passenger floor only (the floor well only)
fills up with a quart to half gallon water when rains and is driven.
No other water evidence from windshield, door or windows or upholstry.
Most of mine in both back doors were either broken, or stripped and wouldn't stay in. Bad window regulators are a very common problem in the Century. My right rear window didn't work at all when I had my car out just before I bought it. Luckily they fixed it before I got it.
No, try finding a same year regal with at least 1 working window. Passenger side one is starting to scare me, but I should be safe cause my drivers switches are broke locking the others from any input. From the looks of it there was a design change on the motors. I did also notice these doors don't completely seal out water cause I found water in the front door speaker brackets 2 days after a rain storm. My last thought was lifting the back seat to see if it comes from the trunk area. There are little tabs to release the bottom cushion.
