My dash lights, AC control lights and tail lights are not working

It is unlikely that these are related however, depending on the radio it is possible. So, I would suggest unplugging the radio and see if the lights return to normal.

If they are still not working with the radio unplugged, then we need to start checking for voltage coming out of the switch and see if we have a multifunction switch issue.

Here are a couple guides that will help with this:

I attached the wiring diagram below that will help with this.
