I've been chasing this leak for months now and can't figure it out. Anytime the car gets wet, water collects in the back seat, mostly the passenger side, but sometimes the driver as well. It was diagnosed as needing a new roof (and the car was nearly 20 years old with the original), so I had it done. Water is still getting in though and my father and I think maybe we found it. Water seems to be coming in where the roof meets with the rear frame or windows and runs down to the back seat. The shop that did the roof was terrible, so there could have been multiple points of entry that have been eliminated down to this or this could have been the problem all along and they lied to me. Who has experience with this and can advise what to do to keep the water aimed for the drain tubes and not my backseat?
