My rubber "seal" that is on the back edge of the driver side door that goes around the window glass gets sucked down when I roll the window down. Anyway I can fix this? here is what happens, It doesn't happen on the passenger side

 

make sure theres no sticky stuff on the rubber or glass. clean it good.

 

Its clean as a whistle. Doesn't seem to happen when its raining/humid out. I cant figure it out, can I just cut that little piece of rubber off?

 

might try some vinyl/rubber restore on it. make sure to get the glass side.

 

Silicone spray or WD40 on the weatherstripping
Wipe off the excess.
