Default Yet another headlamp vacuum question

I've researched many old threads and just can't seem to find one to help me on this one. This pertains to a 1976 car. Headlamps both open well upon main switch actuation. When shutting down the vehicle and headlamps the drivers side goes down as intended but the passenger side stays open.
Probable cause is ____________________________ .
Thanks in advance.
