leaking under dash when it rains on 1996 Chrysler Town & Country

I have had this van for 9 years. It just started leaking under the dash on the passenger side when it rains. It leaks a lot in a hard rain. It doesn't run in always until you begin driving. Then it pours in. I can fill up a gallon bucket by catching water with a piece of cardboard diverting it into the bucket

right under the wiper there is screen that not suppose to get clug some time it does with leave so the drain hole get clog open hood loook under it ther should be a Black flex hose it mightt be clog check to make sure it not
i had the same problum and this was it
Thanks a lot. I posted this last June exactly 1 year today! I got one response and it sounded too expensive, so I kept my bucket in place and dealt with the damp smell. I have driven the van less and less because of this. And today I was cleaning up the interior of the van, vacuuming and spot cleaning the carpet wishing i could find the leak and vwahlah! I get a message from repair pal. It's yours (from May 2) and another one from today and you both say the same thing. I went into the garage, got the cover off around the wipers and there was a clog. Praise the Lord. There was a clog and it was easily cleared. So, I can't wait for a good rain to test it out. Thanks again.
when you fix that clog now you have to fine the hose that run under that to make sure its not alsaw glog

The water drain hole is clogged with debris clean it the problem will go away. clean the area where the windshield wiper motor is located.

Your van will need to be water tested to isolate the leak. I sounds like you may have a body seal leaking in the right front wheel well area.
I have a pacifica and the sunroof will do the same,water will run down the pillers and drip on driver or passenger outside leg if drain holes get clogged on slider sunroofs!! thier are 2 drain holes,one on each side.You need to keep them clrear as well.
My 96 Dodge Grand Caravan did the same thing. I was told about the drain hoses. I checked them. They were clogged. I cleaned them out. P.S. The upper part is stationary. The lower part of the drain hose will pull off if you firmly but gently twist at the same time that you are pulling downward. This makes it much easier to clean them out. They are attached to a clip / retainer type thing on the fender well side of the vehicle. Make sure to refasten this when you are finished messing with them. Cleaning out the drain hoses and screen in the cowling did NOT RESOLVE my issues. As it was explained to me, my problems were not due to plugged drains but more precisely due to poor design at the factory. When it begins POURING like a cow peeing on a flat rock, the vehicles design does not channel all body run off to the drains. Or, the amount on runoff exceeds the drains ability to drain the water as fast as it is coming in. Thus, the water will back up and seep in in the surrounding area following gravity around the cowling and down into your passenger side dash area. Their are a couple of body pockets in there where the water will begin collecting. One of them QUITE LITERALLY will hold nearly a gallon (if not more) of rainwater! It is quite shocking to behold this amount of water cascading down from your dash and flooding the inside of your vehicle as you sit there frantic and stunned all at the same time. (To help drain that pocket of water, - try driving your vehicle partially up a slope on the passenger side, or jacking up that corner, and then the other. Anyway, after 5 desperate years of dealing with this issue, I had developed such an hypersensitivity to allergens (mold), that it was making me quite ill and at this point I was living in this van. I had to tear all of the carpet and padding out. This is what I did to resolve the issue once and forever the last year that I had it. I got a friend to help me. You will want to do the same. This is what I did to resolve the issue once and forever:
1) Remove the hood This is necessary to completely remove the cowling and access the area in question. (Make sure to mark the hinge alignment on the hood somehow!)
2) Remove the windshield wiper arms entirely. (Also important to mark the arm positioning with the wiper motor for proper alignment during the reinstall process.)
3) Remove cowling. there are fasteners spaced out along the length of it that you just turn and they come off. Do not lose them. There are screws that you must remove and you need to make sure to put the right ones back in the right place when you work on
vehicles.( I get a piece of cardboard. Draw a design of my project on it, and as I remove them from the vehicle, I will screw them into the design on the cardboard in the appropriate place.)
4) Clean all around windshield very well. Remove ALL Debris, mold, slime. dirt etc. Usually, on older vehicles the gasket around your windshield has shrunken and cracked or warped or both.
5) Clean ALL Debris from Cowling area very well. I scrubbed my vans area down with soapy water after I pulled the chunks of crap out. Next, I dried it and wiped it down with 99% Alcohol.(BE VERY CAREFUL WITH THIS STUFF! IT IS VERY FLAMEABLE! DO NOT SMOKE AROUND IT OR ALLOW ANY SPARKS OR FLAMES OF ANY KIND AROUND IT! USE ONLY IN WELL VENTILATED AREAS! KEEP THE CONTAINER CLOSED WHENEVER POSSIBLE! DO NOT THROW YOUR RAGS INTO THE TRASH CAN AFTER USEING THEM ON THIS! IF YOU CANNOT USE APPROPRIATE CAUTION SKIP THIS PART!
(The reason that I do it is because the alcohol will strip away and dissolve any oils or buildups.)
5) Using a CLEAR SILICON CAULK / SEALER ,( DO NOT TRY TO SCRIMP AND SAVE MONEY ON THIS! THE ENTIRE OUTCOME OFF ALL OF YOUR HARD WORK DEPENDS ON THE PRODUCT THAT YOU CHOOSE AND YOU DO NOT WANT TO HAVE TO TRY TO STIP AWAY ALL OF THE FAILED SEALANT TO ATTEMPT TO DO THIS AGAIN! TRUST THAT! Use a flexible, clear, all weather caul with a long lifespan preferably designed for this purpose. If it costs less than $10, its probably not good enough.....carefully seal all the way around your windshield. (This will take care of leaks from the windshield gasket failing),
And, THE AREA WHERE YOUR WINDSHIELD COMES IN CONTACT WITH THE BODY AT THE BOTTOM. There is a rubber strip at the bottom that has no doubt, shrunk and cracked. I went to Pick N Pull, and got a better one out of a dead van , seal all around this also.
It has been a few years since I had to do this procedure last, and the details are kinda fuzzy, but I am about to do it again to my new 2000 Chrysler Town And Country.
If there are any discrepancies in my information due to my memory, I will correct them at that time.
GOOD LUCK TO ALL OF YOU DEALING WITH THIS OVERWHELMING AND FRUSTERATING ISSUE!
