Hi everyone. I've got a 99 S80 T6 and I've had a problem with water entering the passenger side from under the dashboard. The A/C is draining properly and I only experience the problem after a torrential downpour (while the car is sitting) or after washing the car (again, not moving). Is this a common problem that can be pinpointed to one source? Consequently, due to the water, I've shorted out the amp to the speakers under the passenger seat - anyone know if this is an expensive fix? Any help on the matter would be great! Thanks!
