Help needed: MF (Manual Focus) problem on 12-60 Pana-Leica lens

I was on the verge of buying a lightly used Pana-Leica 12-60mm lens when a mysterious problem developed: the lens has an AF-MF switch (to switch from Autofocus to Manual Focus) - but when it's put into the MF position, nothing happens (the focus doesn't change) when you turn the manual focusing ring on the lens.

The seller checked the rear positions - where there is a selector switch to go back and forth between different autofocus modes (AFF/AFF/AFC) and a manual focus mode - but changing the position of that mode selector didn't do anything.

Does anyone with familiarity with this lens have an idea what might be causing the problem? or if, possibly, there might be a simple 'fix'?

It works fine in Auto focus mode by the way.

Any and all opinions, thoughts, ideas or suggestions would be appreciated.
