both the inner and outer window seals. some people add add'l insulation to the door panels. I also lubricated the lock mechanism/rods while it was apart.

(Bypassed the Bose setup too. That requires pulling the speakers and wiring around the amps. But mine is an 89. I think your yr is different...don't know.)

If your upper door panel does NOT stay in the channel on the door, you may want to check the 4 or 5 plastic ribs on the inside of the door panels to see if they have split and seperated. I used some small metal braces to fix the problem. Both of door panels on my C4 had split plastic ribs. This is a pretty common problem with C4's, so give a good visual inspection for splitting.
