I have a 94 Buick Park Ave and the rear passenger floor stays soaking wet at all times. The floor is intact no rust. I was thinking the hear coil/core however wouldnt that the passenger side front floor wet? Help
I have a 99 eclipse... the whole passenger side floor is soaked and my rear passenger seat. Nothing seems to be leaking through the top when it rains and I have no idea how its getting that soaked! Does anyone have any suggestions?

Re: Wet rear floor
Have you by any chance jacked up the passenger side, or got vehicle on a hoist to make sure there isn't any plugs on the underside that may have fell out? They could be round or oval metal or rubber plugs, probably in that area.

I used to get water in my trunk when it rained hard. I re-caulked the rear window and it stopped. A water leak has a capillary effect meaning it will follow ridge lines and can appear in unlikely areas after it flows downward. I sometimes get water on my driver side door when I wash the car and spray sideways to rinse. I would check all your rubber seals around the windshields and doors.
The two most common causes are rain water leaking in or the ac drain being clogged up. I would vote for rain water if the entire carpet area is wet.
Could be coming in around the windshield, or one of the door gaskets.
Whenever I see a system which is leaking from more than one or two places, I do a head gasket check because that tells me that the system is experiencing above normal pressures. the wet floor is a heater core. whether it's a water pump or some other thing near it only you can tell. Actually it rarely happens, but the wet floor could be the hose where it meets the heater core at the firewall; again, only you will be able to tell the difference. if the hose connection looks dry, assume that it is the core itself.
do you have a sun roof, if so start there, because there are two hoses at the back corners of the roof pan that allow water to drain, if they leak, they will soak the rear floorboards, and if not that check the door jam seals.(note that if the plugs on the floor are missing that will be verry hard not to have wet carpet)........let me know?
i had this problem too. it was a small rust hole in the wheel well. i took a pieace of aluminum flashing and a can of spray bedliner for trucks and patched it up. it works great! just a thought for you
I had a similar issue and found that the two rear drain holes for the sun roof came off and any water was running down into the trunk and also the rear floor was always wet. I pulled the rear of the roof panel down to expose the rubber tubes, re-seated them with glue so they would not come off again.
