My passenger window had a leak.... it was a small leak by the triangle. I had many posts on the issue but I finally got it fixed. The Crossfire window needed a simple adjustment. There should be a height adjustment and a pitch. I bet if you make some slight adjustments the window will stop leaking.

I think in my case the rubber seal got pressed in over the years and formed itself to the glass. The connection wasn't as tight as it used to be for the window up against the rubber. If you adjust the window it will make a better connection to the rubber molding and should solve your problem. I think the Corvette and all frameless window cars eventually have this problem. Just my opinion.....
