Window panel

[JMCD915]

How on gods green earth do I remove this panel assembly?

You raise the window and tape it up to the frame so it can’t drop, release the bottom of the window from the track then turn those white 1/4 turn fasteners to release the panel. I don’t remember the specifics for then wiring and handle/lock parts…it’s been too long.
