It's possible it's coming in there. I will try the garden hose on them and watch.
I removed my windshied at the beginning of the summer and the part beneath the windshield was totally rotted out, most of what was left of the metal came out with the windshield. I formed and welded in new material at the time. I used lots of windowsealer and I don't think it's coming in around the window. My firewalls were rotted to and I replaced those as well with alot of cutting and welding. Actually I had to redo the door posts as well. Now that I think of it the whole body was pretty rotted when i started, but I only paid 100.00 for it. It seems that the leak further up kept the insulation soaked which rotted everything, I've only owned this tracker for about 8 months. I think if I take the dash out I will see any areas that I could have missed between the two places. I should have removed the dash when I had the window out, but I was in a rush.
