For a while the dashboard lights would flicker. On Sunday there were no lights to the radio now there are no lights to see gas gauge, speedometer, etc. Just everything is black.

It sounds like you have a taillight relay that is going out. To be sure here is a guide to help you test the relay and the relay location with the dash light wiring diagrams so you can see how the system works:

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
