I have noticed I had had a fair amount of water in my trunk lately. At first I would see a little on the plastic tray that covers the battery. I checked the trunk gasket and it looks ok but I put a light coat of silicone on it anyway. Now during the last few weeks the well that houses the jack on the driver side of the car has been filled with water. I drain and dried it twice but it seems to collect more after a few days of rain or if snow is left on the car. The main floor and trunk mat is bone dry so I don't understand where the water is cominmg from. I felt under the rear window and looked with a light to see if maybe the rear window could be leaking but I don't see any stains or feel anything wet. The rear antena is in that corner be I can't believe it would let in that much water. The well just starting filling a few weeks ago and I had no water all summer long except the little bit on the battery cover in heavy rain. Any ideas?
