The water accumulates even when the car is sitting. I have even covered it with a car cover and still got the condensation. It covers the entire inside lid of the trunk. I have climed inside to spot the origin of the water but I cannot. The bottom side of the back deck of the trunk, under where the first aid compartment is seems dry except for a few inches past where the trunk lid attaches to the car. There is no mosture coming from the floor of the trunk, other than the matt, the floor is dry. I have noticed the sunroof seal is deteriorating but is not in bad shape and there is no sign of water inside of the car.
I am thinking it is either the sunroof seal or the rear windscreen seal. I have also looked around a little for a sunroof seal kit but couldn't find one.
Any advise would be greatly appreciated.
