Electrical gremlins

[67-250]

I've got a 67 C20 with a weird lighting problem.

1) No taillights, running or stop but turn signals work.
2) One pull on headlight switch activates parking lamp on passenger side and left turn signal indicator but no action on outside lenses.
3) Two pulls on headlight switch turns on headlights but turns off parking lamps.
4) No cluster illumination.
5) No overhead light when headlight switch is rolled to the left.

I was encountering these problems and replaced the switch from AutoZone today. Still same problems. The dome/tail light fuse is good as I can see it intact.

Is this going to be one of those days?
