Problems Rolling Rear Window Down
Short answer: A rear window that won’t roll is usually hardened grease. On a 1968/69, pull the jamb vent, spray the tracks and regulator drive gear with Liquid Wrench, and work the window up and down until it moves; then lube the tracks and regulator with white lithium grease (both come in aerosol cans).
The rubber weather seal on the front of the quarter glass is replaceable, but the chrome edge is not — look for good used pieces at swap meets or from Arizona/Southern California cars.
