Hey Bill,
 
Thank you so much for your reply. I'll take the car to the dealer...hopefully the repair won't be expensive! I'll post the outcome.
 
Best regards, Leo

Hi! Most of these develop your type leak. Usually it's on the passenger side, but some leak on the drivers side!
 
See my previous posts: the dealer has had dozens of these so he will know what to do. My 2001 Town car did this and the dealer said 'that's a common problem'. Cost fixing it was a little less than $200. That was in January and it hasn't leaked since. Bill Eaton

Hi,
Our Merc Marq leaks on the drivers side. It has been to two different dealers and so far it has been a BIG waste of money at both places and we still have the leak. We are in Winston Salem, NC. Our windshield was replaced, rubber in side windows have been replaced, Seals have been replaced, black plastic tray around windshield wipers have been cleaned out. Love the car but ready to throw up hands. Did you get yours fixed and what was the problem????? Thank you.

Hi! If you can figure out how to get to the past posts there were several who had the same problem with Merc, Linclon TC and Ford Crown vics.
 
Basicly....there is a gasket that is behind that plastic tray under the windshield wipers. That gasket goes bad and when it pours rain.... it leakes. It may leak more one time than another as it depends on how the car is sitting.
 
Dealer replaced that gasket with silicone seal and it has not leaked yet. Dealer says it's a common problem. Cost was about $190 which included the dealer keeping the car for three days and drying out the carpets. Bill E

Sounds like you need to watertest the car yourself. Hopefully you know a little about how to remove interior trim. Its easy . Pull the side plates off and lift the rug up in the front. Park the car the way you normally do ..uphill downhill rightside higher...left side higher. Slide the seat back so you have lots of visibility on the floorpan. Dry it out so you dont get fooled by existing water. Heater will work fine. Get out the hose. clean the hose so not dirt is on it ..dont want to scratch the paint. Approach the car from the pass rear and set the hose on the roof. Put a towel down so the metal hose end doesent scratch the paint. Put something like a block of wood on the end of the hose so that it stays there. turn on the water so it rolls towards the front and down the windshield...and over the front and hopefully rear door. Let the water run. Be patient. Get out your flashlight and open the pass front door so you can observe any water trailscoming in on the drivers side. If your sight is bad puff some baby powder over the floorpan and up the sides . wetness or trails will be more obvious with the powder. Eventually the leak will show itself. Let me know what you come up with. Sounds like we will have to figure this one out ourselves since the dealer doesent know how to fix leaks. I do. All other replies in this section tell how to fix the passenger side leak but they dont apply to a driver side problem. Write back with a full explanation of what you come up with and I will help you figure this out . Been doin this 25 years.

I have a '97 Crown Vic which use to have a water leak on the driver's side carpet. I had to remove the wiper arm on that side and lift that plastic tray up and clear leaves and other debris that had plugged a weep hole. I used a long piece of plastic (12" cable tie worked for me) and swished it around until water began running out behind the drivers side front wheel as it should. I have not had a problem since and it has rained cats and dogs here on several occasions. The whole procedure takes about an hour as there are five or six screws to be removed and a plastic snap off rivet to be removed but you only have to do this once. Hope this helps.

I came across your post looking for ideas on how to fix mine, and sure enough I've seen here that a lot of folks are with the same problem. I know were the water is coming in, right thru the lower plenum (I think that's how is called) which indeed is the lower portion of the outside vent. I did the clean up and check up of the gasket but it looked good to me I applied a bit of plummers putty to the
far right side of the gasket to cover every gap, and still it leaks when I put the hose like you said on the roof towards the right side of the windshield. My idea is if there is a gasket right at the firewall were it meets the
plenum inside the car, how can I replace this without messing to much withtall that plastic, my Grand Marquis is a 92 and after all those years things can get pretty brittle.Thanks for your help.
 
Mike

Hi Mike! I think the only sure way to stop this leak is to do what the previous posts say. The dealer did my 2001 Town Car, but charged me a little less than $200.
 
I think Ford Motor Co should have had a recall on all these Ford Crown Vic, Mercury Marq, and Lincoln town cars to fix this problem but they have not! Bill Eaton
