Water Behind Rear Passanger Door

[chrisjr123]

After our monsoon last night opened rear passanger door and heard water sloshing back and forth. Haven't had a chandelier too look at it yet just wanted to see if anyone has had this problem before? Vehicle is 07 NBA sierra no sunroof 4 door. Thanks

x2 on the third brake light. It will leak and roll down the sides to the door. It will also cause leaking in the corners of the headliner. My GMT900 had this problem and few years ago.
