1994 Plymouth Voyager Leak in dash

Electrical problem
1994 Plymouth Voyager 4 cyl Automatic 99,400 miles

I bought this vehicle used about 6 months ago, and I noticed the carpet was a little damp a few days after purchasing it, right where my feet rest on the drivers side. It went away so I forgot about it.

Recently the leak came back. It comes from under the dashboard on the drivers side and falls directly on my brake pedal. My dad though that it was the heater or something like that and rerouted the pipe so I can no longer use my heater, but he said the leak should stop. It didn't. He then blew air threw the pipes to remove any water, and went me home again. He said there may still be a bit of water left inside, but it's still leaking, and more than just 'a little'. When I go around turns, it's pouring onto my feet, soaking my shoes. It's also ruining my carpet and creating a horrible smell.

The biggest problem is that it's messing with my electrical stuff. It causes my windshield wipers to turn on at random, or whenever I use my left turn signal. It also causes my interior light to constantly be on whether or not the door is open.

I honestly don't believe my father was correct. :/ What can be the source of all this water? Other than today and the day before, it hasn't rained in awhile. It leaks even with no rain.

I live in West Palm Beach, Florida. My boyfriend thinks humidity may have something to do with it.

Hello -

To better assist you please tell me if your model is just the Voyager, or the LE, LX or SE. Also please tell me your engine size in liters and the 8th digit of your VIN.

Is there a certain color to the fluid... That is... Is it really just water or could it be coolant?

Please check your coolant level so we don't overheat your car if it is.

You said it went away, then came back... Do you remember what was going on with the weather when it started coming back?

Have you asked the previous owners about it?

Does it happen several days after it has rained?

Have you been running the air conditioning? It will cool the air and condense the humidity out. The water drips into a plastic pan and drains out in front of the firewall. The rubber tube can get plugged causing the water level to rise and slosh out onto the floor. The tube is a mushy gray rubber and has a squeeze-type ring holding it to the outlet. It's on the firewall, about 8" right of the exhaust pipe, (towards the passenger side). The tube is molded into a right angle, and about two inches of it hangs straight down.

Squeeze the hose and watch if some junk comes out with some water. If not, squeeze the ends of the wire ring and pull the hose off, then stick something into the outlet to try to dislodge any debris.

Normally, if this passage is blocked, the water drips onto the passenger side, not the driver's side. You might try watching under the dash while someone sprays the windshield with water.

The Chrysler or Dodge dealer's Parts Department has a spray can of air conditioning duct deodorizer to eliminate the musty smell.

I apologize for the late reply. My birthday was on Wednesday so I was away.

It's just the regular Voyager, I don't know the size, and it's too dark for me to be able to find the VIN number. I can do that in the morning if it's important.

The liquid is clear, like water. It's very, very cold to the touch.

Coolant level is fine.

I believe it's because of my AC. I've been testing it and it seems to only leak when I have the AC on.
It's also getting worse, now leaking on the passenger side as well.

I asked the previous owners. They claimed ignorance. I think they either knew it was there and didn't understand why, or they didn't want to deal with me.

Rain doesn't affect it.

As I said above, I now believe it is caused by my AC. If I turn the AC on for about 10 or 15 minutes, when I go around a turn, it pours water on my feet. I was driving with sandals on a few days ago and the water got on my feet. It was freezing cold, even though it was hot outside.

I will have my dad look at it and do the things you suggested. Thanks for your help so far. If you have any more ideas after this info, please let me know.
Thanks.

Hello -

Nice to hear from you - no need to apologize. . .. . .. . .. . ..

Well, happy birthday! Hope you had a nice one.

Don't worry about the VIN for now. . .. . .. . .. . .

Hopefully it is a simply problem. . .. . .. . .. . .. . ..

I believe your evaporator A/C drain tube is either blocked or not properly connected. It should be located on the passenger side. . .. . ...you should be able to look at the firewall under the hood, look for the A/C lines that go into the firewall. . .. . .. . ..then look down below them.

There should be a drain hose that comes out and either points to the ground or just sticks out. You normally see water under cars during the summer, that is the condensation draining from the hose. . .. . .. . .which isn't from yours. . .. . .. . ..if it is blocked or not connected right, the water will fill up your HVAC housing and then run to either the passenger or drivers side to drain out.

If you look and you don't have one, then that is your problem, get one from the dealer and install, they just push on and you are good to go.

If it is there, I would pull that hose off and see if it is plugged. If it isn't then make sure it is counted good.

If it is connected then I would take a rod and GENTLY push up (you can remove the hose) and move it around to clear out any blockage. You could use an air hose but go easy on the pressure.

Okay, just happens I am working on the AC of a Mercedes Benz. . .. . ...so I can give you a few pics.

The first pic is from looking in the engine bay. The circle is the A/C lines going into the car at the firewall. On this model, the rubber tube that the water comes out is behind the shield where the arrow is.

The next pic is from inside the car. . .. . .. . ..the circle is the end of the hose that connects to the HVAC system to drain the condensation. The arrow is the part where the AC lines come into the cab.

The next pic is the outside part of the HVAC that the hose connects to. The entire HVAC is inside your car. . .. . .

The last pic. . .. . ...the arrow shows the drain hole that the condensation collects and drains out to the rubber hose then out of the cab. As you see, this is the lowest point in the HVAC housing. So it fills with water since it cannot drain out and flows throw to a point to leak out. Now be careful as the evaporator sits right there so you don't want to push too hard or you will poke a hole in it then you will not have any AC and you will have a tough time replacing that!. So poke easy and use the air.

I think this will fix your problem.

Hello -

Hey, one other things. Also, it looks like you may have some recalls on your vehicle. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you.
