Jordanjeeperr Sorry its been so long, work has been killer but i finally got that cowl off and the vent directly under the full cowl vent holes all cleaned out with a yard stick and all.. i started it up let it warm up and everything.. NOTHING hah theres another cent kind of thing to the passenger side under that cowl i dumped a little water down that and sure enough water came trickling down to my passenger floor again.. im guessing that water must of shorted something out.. theres a would tj heater set up on craigslist 2hours from me for 75bucks.. think maybe ill just have to go pick that up..

Red Dirt Dauber I had a '99 TJ that the heater stopped working. Turned out the heater core was stopped up. One easy way to tell if that's your problem is to check the temp of the heater hoses with the engine running and up to temp. Feel the hoses near the firewall. If all is well one should be a little hotter than the other. If neither are hot, you definitely have a blockage. One other thing to check are the "doors" on the heater under the dash. These are vacuum controlled and the hoses can break or slip off easily. Good luck!

if its raining thats perfect, get a step stool and look into your cowl, if you see water you have found the problem.

most of the ones i have cleaned out were not leaves but all the little crap that falls from trees in the spring

X2....Pull the cowl off in front of the windshield, and stick something long and flat (like a yardstick) down through the bottom of it. There's a rubber flapper on the bottom that you can't really see. Kind of open the flapper with the yard stick then use a hose sprayer to flush out the debris down there.

Your heater issue is probably not related to the water on the floor unless there's coolant in it.

When the cowls get plugged you will get extra water coming in through your dash and near your heater core. The water could have messed with your resistor and possibly other parts of your heater system.
Remove wiper blades, remove cowl panel (4 screws I believe) and clean out the large cavity of all the crap in there.
Do you park under trees a lot? Leaves will accumulate inside the cowl area. It's also a good idea to run a wire or something inside the rubber a/c drain hose to make sure it's not plugged as well.

Good luck

Please help!

I have a o4 wrangler x, when i got it about a year ago the heat and air worked great. All summer it had a huge puddle when the air was on, never thought that was a big deal.. but then i notice maybe six months ago that when i would go in car washes my passenger floor would fill with about a half inch of water. Never got around to looking at it.. now my heat wont work. If i turn the heat on full blast it just slowly seeps out... Im guessing this is all related to the problem.. anyone know what i should start looking at? Do i need to take the entire dash apart to get to whats wrong?
