Problem Removing the AC Shroud

Have you tried lightly tapping on the end of the screwdriver with a hammer while you're applying twist? That has worked for me in a few scenarios.

When I removed my shroud last year, it was similar, even though it has been trouble free in the past. Dunno what caused it, and it went back together fine. Actually, I think I may have ended up using my Ryobi One Plus impact wrench to remove them.
