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.

Dodge Ram 1500 Water Leak Due to Faulty Rear Window Seal
Dodge Ram 1500 Problem
Average Mileage: 58,084 mi (17,000 mi - 174,658 mi)
Water leaking thru rear window seal and flooded the comparment under the back seat
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.

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.

Same as above...water building up on the storage wells under the seats and water damage to the back of the back seat, rear area under the window and carpeting.
On my 2007, significant amounts of water would come in after a hard rain and collect under the rear seat. I applied clear silicone caulk around the outside of the rear window and it did not stopped the leak at all. The next hard rain the problem . Is there a record on such a problem?
