I think thats what it's called, the part that the widows actually goes inside of when you roll it up. It's jacked up on both sides on my accord so it doesn't seal, where can i get this stuff and is it easy to install

sorry if in wrong section, i was gonna put it in appearance but then thought it might be different for different models.

 

You're talking about the run channel. It's a big rubber seal that starts at the front bottom of the window, wraps all the way around the door, then back down into the door on the window's back side. If opening the door panel and removing the glass doesn't scare you, it's a peice of cake.

Make sure the regulator is good, if it isn't now is the best time to replace it.
