Water Leak in passenger rear floor. on 2001 Lincoln Town Car

I had a 2001 Towncar and water would collect in passenger rear floor after any significant rain. I sealed the grommet on outside bottom of rear floor, then I taped all the door and body gaps and still had same problem. I looked under hood and found a rubber drain below windshield with flap door and it was clogged with leaves. I cleaned it and took offer cover under windshield wiper and cleaned a drain screen there. The leaking seemed to stop but shortly after started leaking again. I just bought a 2005 Towncar and the first good rain, the rear floor had an inch of water in it. At that point I decided there is some flaw in body . Does anyone know how to fix this problem Rgs, Larry

You did what I was going to suggest in checking for clogged drains at the windscreen, I would also think about clogged sunroof drains. It is best to look for water leaks when everything is dry. First is the door seal or door, damaged in anyway? I have seen the seat belt having damaged the door seal on many vehicles. Do the doors close flush with body? Ensure the door seal makes good and uniform contact with the door (particularly important if the vehicle has been involved in an accident. You may need to pull back carpets pull back the carpets and sit inside the car (you may need a flashlight) and get a friend with a garden hose to spray water around the door jams to determine if the water is entering the doorway. Then spray water around the windscreen moving around the circumference of the windscreen. Look around the windscreen area and look up from the floor mat area (as best you can) to determine if water is leaking in around the windscreen seal. Is there any rust around the windscreen area or body work? If you have a sun roof there is a drain tube at each corner of the roof to channel away water. A blocked drain may cause water to fall from the sunroof area Water can also come up through the floor pan as you drive through water on the road, if any rubber bung or “seam sealer” has been disturbed or is missing.

Hey Larry! Yvonne (Delaware) having the same issue with a 2005 Towncar. This can't be an unknown coincidence- Have you found a resolution for this?

Bought mine brand new in 2004. LTC Signature with the same lake of water in the back passenger floorboard. Has previously live a long life garaged. Will try the Ford Dealer first, but I am with the other post of having Lincoln send out notices so that people will be aware. I rarely use the back and found my wet floor by accident. I guess Ford is overcompensating for all those Fords that exploded while parked. So I guess this isn't so bad? What do you expect for $47,000.00

2005 Lincoln Town Car rain water collecting in right rear foot well. Got appt at local Ford dealer. Waited 1 hr for repair. Paid $77. Was told that the door seals had come out of place and they reglued them back in. This made sense to me as I had been carting large items around in my back seat and I probably bumped the seals. Their fix worked as it has been rain tested several times. The trick is to find a reputable, competent and honest repair facility. One Lincoln dealer estimated the repair at $700-800 and I would have to leave the car for an extensive diagnostic process.
