I work for a autoglass company and we do the glass work for a local Chevy dealership. In the past 8 months we have had at least 15 cases of water puddling on driverside floor. In every case there was a tiny spot on the driverside top corner where the urethane adhesive wasn't touching the pinchweld. So under heave rain or high pressure, water would work its way in and collect on the headliner and either run down the a piller onto the floor or drip out the overhead console.
