Check the fuses first of all. Look at the wiring harnesses for evidence of critter damage or loose connection.

I checked the fuses but have not checked the harnesses yet. I’ve seen quite a few reports about problems with the cluster but I’m confused as to why the radio would go out at the same time. Are they connected some how?

A bad ignition switch did that on my Bronco. Wiggle the key to regain contact proved it.  
( – switch – not key cylinder )  
All those things are common at the ignition switch, that is why you see them ‘off’ as you turn the key to crank the engine as you start up…release the key when started and all systems come on, unless…
