Thumbs down Water coming through dash when it rains

Well the title says it all. Whenever it rains I've got water coming through the dash in a couple of places. It's at a dripping rate. It's enough to get my pants leg noticeably wet if I'm in the jeep for over 10 minutes or so. It makes me cautious of having stuff in the floor in the passenger seat too. It's had some electrical work done to it from a previous owner which makes me wonder if they pulled something out and never put it back? It's a 1990 model. Is this common? Any ideas?

Probably the drain for the heater core box is plugged or pinched and filling with water

Hey Y'all! Watch this! I saw it in a movie once!

I had this problem and after trying a few things I finally thought about the cowl seal between the tub and the windshield frame. I replaced it and no more drippy dash. Good luck P.S. It WILL go from a drip to a drizzle pretty quick. lol I'm pretty shure this is the one I went with. 87-95 Jeep Wrangler Windshield Cowl Rubber Seal Gasket - eBay (item 270621272115 end time Jan-09-11 08:45:59 PST)

It is as easy as folding down the windshield and removing the old cowl seal and putting on the new seal after cleaning both sealing surfaces real good .
should take ya about a hour at the most.

you really do need to make sure your heater core drain is clear also.

doing these two things will fix your problem

Either cowl windshield seal or heater core intake box.

The cowl drain tube is on the firewall just to the right of the battery. (Big rubber tube can't miss it.)
For cowl seal replacement read up here:http://www.wranglerforum.com/f8/repl...eal-71120.html

Mine leaked from the holes drilled in the windshield for the soft top track. It would fill up the windshield frame under the wiper motor until it overflowed into the dash. Usually it would drip on my left pant leg. When I finally went to fold the windshield down last year most of the most of the windshield frame stayed where it had rusted out.

On my new frame I drilled hole under the top frame so I could use bolts instead of screws for the track for the soft top. I put the bolts in with rubber washers when the hard top is on to keep the holes sealed.
