Well I checked the car over. The small rubber grommet on the bottom of the hatch lid seems to be intact. I didn’t feel any moisture in the spare wheel well although there is carpet in there covering much of it. There didn’t seem to be any cracks in the sunroof rails. I’m not sure how I’d find out if the drain is clogged? There was a small bit of moisture on the front part of the sunroof frame. Unclear if that’s also condensation. There isn’t any wetness on the carpet or mats. The edges of the headliner near the windows seemed dry. I did replace the windshield this summer with an OEM one. It didn’t seem to leak then, but I guess that’s a possibility? Any other ideas? As you can see there are large water droplets on the inside of the windshield.
