Man, that's funny. Steps....
Pull door cover
Remove plastic insulator (don't tear!)
Drop window
Pull rubber seal
Stand back and have a drink....
Maybe a sammich, while you are at it....
Slide in new rubber seal
Raise window (up and down a couple of times checking seating)
Tack plastic insulator back on
Replace door cover
The most time you spent on this job was having a drink and eating a sammich. Shops are hurting in these tough times so, can you blame them.
