My 736 and 737 overhead panels have knobs where they shouldn't be and knobs that don't have click spots.  My 738 and 739 planes are working fine.  It's mainly the air conditioner system is.  And a few other spots.  Can it be fixed or should I just reinstall the 600/700 base again.  It was working, but I mostly fly 800/900s. 

Perhaps you might have luck by running the PMDG 737-600/700 expansion package installer and selecting repair?

And if that doesn’t work turn AV off and reinstall.

Regards.

Doing a repair did the trick.  Thanks
