Electrical gremlins

[Grumpus Monkus]

So just over 2 years later the ol' girl is up and running as of today. She seems to run and drive fine, but we noticed a few issues:

Tail / brake lights don't work, fuses appear to be good.

Electric windows won't go down, again, fuse appear to be good.

Floor switch for high beams, we get all 4 headlights, and when we press on the floor switch to turn the hi beams off we get no lights at all.

No turn signals

And the windshield wipers like to come on randomly even thought he switch shows them to be off, a new switch was put in when we bought the truck a few years ago because the PO said the wipers don't work. They did after the switch was replaced, but again, now they come on randomly.

Any thoughts?
TIA
