water leaking

My 95 YJ leaks bad when it rains. My feet get soaked as water pours in from somewhere up in the dash. Any suggestions? ??

There are vents up under the dash that open and close (or supposed to close) with vacuum. When you switch the heater control to vent it sends a vacuum signal to open the door that goes to the passenger side, and a cable does the door on the drivers side. Sometimes the cable gets rusty and sticks open a little, and this lets the rain in.

The rain is going into the vent on the cowl, and running into the heater.

You can check the vent drain tube which is located in the engine compartment, on the firewall just to the passenger side of the motor. Comes out of the firewall and points down toward the starter. It's about 1.5" in diameter black tube. Sometimes it gets clogged with mud or debris.

For a more detailed idea of the vent doors, look at the top of the Tech forum page under the heading "YJ heating system explained".

My vent tube was 50% full. I also took some PB Blaster and sprayed the mechanism on the passenger side vent. Now everything works perfectly.

So after doing all of the cleaning and lubricating we had another rain storm. Water is still coming in from under the dash somewhere.

Any more ideas?

Check out the thread called. "YJ Heating System Explained". I think it's a sticky. There's some really good explanations of how the hvac system works, which could help diagnose any possible leaks coming through the cowl.

Btw, i checked out my vent tube and it felt like Chicago sausage it was so full! Cleaned it and no more leaks.

I have the same problem... I pulled that hose and it was full of stuff too... but I don't think that's the problem... I end up with a lot of water in my floor boards... maybe a half a quart sometimes... and there is no rhyme or reason to which side gets wet.. sometimes driver sometimes passenger.
Last night I after drying it once again, I found a little water leaking in from the side of the body... like it's coming in from the door hinge area someplace....
what's funny is it doesn't get wet in the jeep after I wash it....
pretty weird...
