Having problems with your 1999 Plymouth Voyager ?
Water dripping on the floor from under the dash on passanger side
I to had same issue bought van used later july of this year. I took the wipers off took the surounding cover off last month. and found that there were 2 drain holes that were pluged just enough to cause the water to over flow into the blower motor comparment that is under the dash on the passenger side. I olny noticed the water after like 2-3weeks of owning the van. On a few occasions when taking off from a parking spot after car has sat in the rain for a while ot turning a corner I would water running and draing to somewhere kinda like as if it was coming of the roof but no water was visible. I have a police/fire scanner in my van mounted on a 2x4 in between the 2 seats as I am a Volunteer Fire Fighter and have the wire for the antenna running in the rubber gasket of the drivers door. I had the owners manual for the van sitting on the passenger seat and it fell off in between the seat and the door. I did not pick it up for a couple days and I found it to be wet when I whe I did pick it up. I found the carpet to be soaked between the door and seat I found out the way I had the wire ran for the antenna allowed water to follow the wire in to the gasket ant down to the bottom of the door frame. I made a couple ajustments to try to solve it. A few days later I glanced over at the right moment to the floor under the dash on the pasenger side and saw what looked like water start to come up through the carpet and a couple dops on the top of the carpet. l was like what is going on why is there so much water and why is there water drops on top of the carpet. As soon as I could I took a look to see why there was that much water and looked under the dash and saw there was a few drops of water hanging of a screw I wiped it dry to only to see more water appear. I had thought somehomw maybee what I did with the antenna wire it allowed water to follow its way along the door opening and into the dash. I stated because the screw was up near the firewall it cant be because of the wire. I started to get a little worried as I saw wires going in to the the part under the dash wehre the water was driping from and thought maybee I better remove the screws and see where the water is coming from as I did not want something to short out. I removed all the screws holding the cover on and founf there to be a littel water pooling in there and found that up in that comparment whi\\ch I found to be the blower motor comparment a padded flap that was soaked. I pulled the carpet back along with the padding as it was all soaked to take a shop vac and **** out all the water I could and to allow it to dry the rest of the way and while I did that I saw a line of what looked the a streak of slight rust on the plastic that covers the fire wall and determend that the water had been collecting in the blower motor comparment for a long ime before I even got the van as the rust lined up with where the water was dripping in. Since I have cleared the 2 drains I have not noticed and water coming in nor do I hear all the water sloshing around. I have yet to reassemble the blower motor comparment as I was not only allowing it to dry but I did not want to have to open it up again if water leaked in again. But I plan to try and reinstall it this weekend as I am starting to need the defroster as the cool weather is coming and windows are foged up some at times in the morning and with the cover off do get full air flow on window.
We had that problem. It's probably from the drain pan under the windshield. What you can do is remove the drain cover (attached to it are the windshield wipers). On either side you'll see a drain hole, probably one or both are clogged somewhere in the line. Fish a wire through the two drain lines (we used an electrical snake) until all the leaves and pine needles and junk come out under the car. Pour some water through to test, and you should be good to go. Good Luck!
