the car is a 91 crx. whenever it rains, water drips relentlessly between the door and the roof, soaking the sides of the seats. the weatherstripping is there. do i just need to replace it? any other thoughts/suggesions?

 

you mean water actually comes in at the top of the door between the door and roof? best way to check how tight it is is to put a dollar bill in between and close the door. If you can pull the bill out with no resistance the seal is worn. You can either replace the seal or roll the window down and pull the door frame towards the body. BE CAREFUL if you do this so you don't tweek the door too much.

Hope that made sense and helps
