My daughter's newly acquired 244GL leaks water onto the front passenger seat from the sunroof. When I bought the car, the previous owner had black electricians tape sealing the opening between the sunroof and the roof. He said it leaked because the seal needed to be replaced. The seal is a little torn in spots, but not bad at all. The open/close mechanism works fine. I removed the tape, opened the sunroof, and stuck a coathanger down the front drain holes. I tested the front and rear drains with a watering can, and they all drain water. Any ideas why the leak is happening?
