Question where's my leak coming from?

Every time it rains my 95 YJ jeep leaks from the dash. I put a new top on and sealed the clip rail above the window. No idea where the water is coming from?

When it's not raining, get a garden hose running at a trickle. Try one upper corner of the windshield. See if it leaks. If not try the other side. See if it leaks. If not then try the middle and see if it leaks. If not then repeat but from the roof right above the windshield. If nothing still then get a small cup of water and try it along the top of the windshield with the top pulled back. Locate where the water goes in to create the leak and then you can decide a course of action.

A common area that you will get a leak from the dash is a black hose on the firewall. It is tapered so that it closes on the end. Mine was gummed up with dirt and leaves when I got it and every rain or whenever I washed it, my feet would get wet. To solve the problem, simply squeeze the bottom of the rubber hose and it will drain onto the ground. If you have any more questions or if that is not the problem, I am sure someone else will assist. Good luck and welcome to the forum.

I would also get some water coming in the hood cowl then dripping out the heating vents on the floor

I replaced the stock cowl with one kind of like this...

Is the water showing up near a side or more in the center of your dash?

Jeff, You are 100% correct. After a hard rain my 92 YJ Wrangler would have a cup or two of water run down the interior firewall where the clutch and brake pedals are. Usually after I made a sharp turn. The tube you mentioned is hooked to the air intake box under the grill and screen that is in front of the windshield. The tube gets plugged up with dirt etc. The box will hold water unless it drains out through the tube. You can squeeze the clamp to the tube with your fingers and remove it easily from the firewall. I did not need any tools other than my fingers. I did use a phillips screw driver to remove the grill and screen. The water was coming in through the rubber flapper which opens when you put your heater controls on VENT. It should close when you put it on floor heat or defrost .(I do not have AC).
