On some models a void in the rear window seal may cause a water leak. Water may be present on or under the carpet. The seal will need to be replaced if that is the source.Google+

My 2008 ram 1500 rear window has been leaking for a year and a half. dodge is on their 10th attempt. 5 new windows have been placed in. it seems that whoever made the slider window didn't know how to make a quality window.
On my 2004, significant amounts of water would come in after a hard rain and collect under the rear seat. I traced it to the third brake light, instead of the rear window. I removed the third brake light, applied clear silicone caulk, and reinstalled. It stopped the leak completely. I know I may have a hard time removing the lens again if the bulb goes out, but I figured stopping the water was more important.

Any time it rains or I wash my truck water comes in the very back window around the middle

Back window leaking again. Complete window replacement 2 yrs ago and now leaking again. Dodge refuses to admit that there is a serious design flaw. My next truck either won't have a sliding glass back window section or won't be a Dodge.
