For me, it is the seals around the sliding rear power window on my 2007 Ram....the seals have shrunk leaving cracks at each corner of the sliding window.
I have not been able to locate a source for new rubber seals and although I have posted requests on this and three other forums in hope that the seals are available somewhere, no one seems to know where to purchase the seals, including the local dealer. Maybe some of the dealer shop guys on the forum can look into this problem....it is effecting a lot of us... If someone could at least tell us who made these windows for Dodge maybe we could source new seals directly from the manufacturer.
So far, the only solution available to everyone with this problem has been to seal the sliding window up with RTV or other sealant and say goodbye to the sliding window...or replace the entire window with a solid backlite.
Right now I have my backlite sealed with Shoe Goo because of all the rain we are getting in the S.E. right now....and Shoe Goo was all I had on hand....
One other thing...there are weep holes for drainage that leads from the sliding window track to the outside. They are simply not large enough to handle my leak, but I did blow mine open (they were clogged) with my air compressor. They are located 6.5 inches in from the lower corners of the backlite....the entire backlite not the sliding window. In other words measure inbound from the lower points of the window (outside) 6.5 inches, make note of that location from inside of the cab (the holes are actually under the sliding window cable so you cannot see them), take an air compressor and blow down past the cable and hopefully you will see debris or water blow out the back of the cab from up under the window. It took me a while to find mine and blow them out, but as soon as I did it was obvious and after that water would indeed slowly drain. I do not know if those weep holes were intended to drain any water that leaks past the seals or simply to drain any water caused by condensation. From the information that I gathered about them they were often plugged by sealant when the windows were installed at the factory. I also read one post where the owner drilled new drain holes....I am not sure I am that good with a drill....but I am about to try that if I do not find new seals.
By the way....these "seals" look just like window Sweeps or Dew Wipes like on the side windows....does anyone know if these are the same??
Keep us posted on your progress!!
