I would check the connectors there maybe some oxidation.

Also, you should jiggle the bundle of wires under the dash. I lost my dash fan and it was due to a bad connection. They use a lot of butt connectors and one of the ones stopped making contact. There is a large bundle of wire that are taped together that are hanging by the radio. Could be that you have the same issue.
