Rear Window Sticks
Short answer: A sticking or off-track rear quarter window is almost always hardened 30-year-old grease and/or a broken plastic roller. Clean out the old grease, re-lube the track and rollers with white lithium grease, and replace any broken rollers (about $3 each from Classic Industries).
Access:
- On 1968/69 hardtops you can reach the rollers and track by removing just the black flow-through vent at the quarter (one screw) — no need to pull the side panel. A long straw on a can of Brake-Kleen helps flush the old grease; then white-lube and work the window up and down to spread it.
- 1967 hardtops and all convertibles have no flow-through vent, so remove the side panel (or at least the U-shaped weatherstrip).
- If lubing doesn’t fix it, a roller is broken and the glass must come out to replace it. The chassis service manual and Fisher Body manual cover the procedure.
