I need to replace wiper motor on...

[falcor]

I need to replace wiper motor on 2008  29 amberjack, starboard side..  any ideas how to remove the headliner?  I see about 4 small plastic "buttons"  If I pry them off does anyone know if there are screws under them?

I have a sundancer but the plastic buttons on mine pop off and screws are under them.
