Insert the point of a spudger in the gap between the vibrator and the frame.

Pry up with the spudger to disconnect the vibrator.

If you're having trouble separating the vibrator from the frame, apply more isopropyl alcohol; it may take a while for the adhesive to loosen.

Use tweezers, or your fingers, to remove the vibrator.

If there's any alcohol remaining, use a lint-free cloth to wipe it off or allow it to dry completely before installing a new vibrator.
