The car was parked up hill nose first. The upper rear drivers quarter panel was wet. The seat back and cushion were soked. There was a puddle on the rear floor on both sides. I pulled the seat cushion out and it was wet on both sides (more so on the drivers). The trunk is dry including the spare tire area. The doors, sunroof and windows were all fully closed. All of the seals around the windows and doors look in tacked. I have no idea where this leak is originating from but since the rear upper drivers quarter panel was wet I'm thinking it some how is making its way through the rear window seals (even though they appear in tack).

I wet vacuumed as much as I could but I think we are going to have to take the seat to an upolstery shop to have them remove the cover and squeez out the cushion.

 

It was a clogged drivers sunroof drain.
