56 Buick Posted March 24, 2019 Share Posted March 24, 2019 Hi all The vent window manual regulator appears to have an issue on my 56. When the vent window is closed its almost as if the winder sits too far in because as you turn the winder it hits the decorative trim above it. And as you continue to turn the winder, the winder then spirals out leaving a gap between the winder and the door panel. Anyone come across this problem? I haven't taken it apart but I assume the regulator mechanism is worn/broken and is one of those unrepairable items. Do any of the other GM makes for that year use the same mechanism because I am guessing it will be easier to find a tri-five chev part? Any info or advice would be appreciated.

old-tank Posted March 24, 2019 Share Posted March 24, 2019 You will find a missing piece of your regulator in the bottom of the door. I drill and tap for machine screws after cleaning and replacing the old grease. Link to comment Share on other sites More sharing options...
