My 1997 GMC Sierra Crew Cab came with a C.R. Laurence rear sliding window and while driving, my wife says that you can definitely hear air through it. So upon closer inspection, it looks like the window frame was not sealed properly or it is coming lose. Check out the pictures below and let me know if there is a fix for it or is a new window in store for me. Thanks, Brendan

That sucks but i have a slider on my 07 and i noticed that it seems when i look close it's not making a perfect seal i'll check more closely tomorrow good luck i don't think you can do much maybe a little clear silicone temporarily
