Same symptom in two tahoes I have owned. Both times the culprit was the rear side glass seals on both sides. Fixed by running a line of rtv sealant where the rubber seal meets the roof above the glass. Ill try to get pictures up soon. While you're up there may as well seal around the roof rack mounts and the third brake light.
