Wet carpet in 2001 lincoln town car

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.

Could be several things:-

1) Pollen filter blocked, needs changing.

2) Sunroof drain blocked, my car is different but the sun roof drains down a tube which eventually goes down the rear of the front wing. There's one both sides. To clear, take the wheel off, take the inner wing shroud out and clean all the mud that has built up underneath it, Then make sure the tube is clean.

3) Faulty door seal, check your door frame seals.

The rear ac evaporator box is not draining very well,and it is blowing the condensation up threw the vents,most likely.The drain should be under the rear passengers side wheel well.

is it only when the ac is on? there is a pan under the ac unit that has a hole in it to allow the condensation to empty. if that hole gets plugged it could cause the condensation to build up and back into the inside of that car. i unplugged mine and floor stayed dry

you need to get car on a lift and look under it there should be four floorpan body plugs that are loose, rotted or fell out. and water for the road is now getting yor carpet wet.the plugs are on the middle of floor for ds. ps. rear and ft. you will need to reseal them or replace. hope this helps

the drain for the ac system is clogged, open the hood ond on the passengers side on the lower side of the firewall there is a small tube that drains, try leaning it out with a pipe cleaner or screwdriver.

The AC evaporator units have a drain hose that runs through the floor because condensed moisture is a fact of life with AC units. Yours is plugged. You will have to get under the vehicle and look for the hose where it comes out, then take like coat hanger wire and clean it out, It is somewhere in the vicinity of where the passenger foot well meets the fire wall. If you have to raise the vehicle to get under it, make certain you have it safely supported. If you don't have the stuff, drive the passenger side wheels up on a good curb and use some cardboard to slide under.

I had the same problem in my Lincoln Town Car about a year or so ago. Here is what the problem was. There are a couple of air ducts at the back of your hood (top of firewall just below the base of your windshield wipers anchor points) These ducts are located one on the driver and one on the passenger side. Each of them has a little gate at the opening. The gates on my car were clogged with leaves and debris, thus causing water to flow over the ducts into the passenger compartment of the car. These ducts must be cleaned out so the water can flow through them and down to the ground instead of overflowing due to clogging.

You have drain blockage in the condesor case itself. There is a small tube that will drain the condensor case, the big black plastic case that contains most of your a/c system inside the car. This case collects moisture and that must drain normally from the case drain to the outside of your car onto the ground.. If this drain is plugged, you will have leakage on to the floor. If the moisture is allowed to remain in the carpet, mildew will set in and then you will have to replace the carpet.

I am the original owner of camry xle 1998 with wet floors. In 2000 I had drivers side door seal leaking at welt. Removed old door seal and new weather strip on drivers side installed. The door panel was never wet, but wet at bottom of door where there are drain holes...slowly leaking under carpet.
In 2001 later water again. Coming from overflowing A/C evaporator-drain plugged/ tank full of debris. Removed evaporator, cleaned + drain cleaned.
In 2003, driver door seal against window rotted. Removed door panel and found leak at window belt molding at the mirror joint inside + out. Lots of mold under carpet needed to replace! Made a fuss at dealers for reacurring problem and they replaced the carpet for free.
