Stuck on removing instrument cluster

[maloryII]

Hey guys, been working on the truck this weekend. I'm trying to remove the instrument cluster, but I can't figure out how to get the headlight and windshield wiper knobs off so I can pull the sucker out??

They don't screw out, the windshield wiper has a tiny screw holding the knob on, but the headlight knob has nothing.

Does it need to be removed from the back of the dashboard? It's very hard to see back there and I'm not sure where to start.

Help would be appreciated!
