wiring digram or any advice would help

Check all of your ground points, make sure they are in good, clean condition.
Either, there are some chaffing wires or a couple of connectors have a bit of corrosion on them.
Electrical gremlins are tough to eliminate.
Might be time to invest in an alldata subscription.
