Water Leaking in

I had the same problem on my Duster. What i did to fix it was unstop the drains. I took a coat hander and ran it through the drain holes in the cowl area. Shoulda seen all the crap that was built up in there, probly took 2 hours or so of fishing all the leaves and trash out, then i blew it out with the air hose and ran water thru it a few times to make sure it was draining like it was sposed too, hasn't leaked since then.
