no hazards or brake lights

[Dead Parrot]

2nd the thought on the silver flasher units. You have one for hazards and a different one for turn signals. Possible the hazard one went out years ago and explains why those didn't work.

The fusing for the running/brake lights isn't always intuitive. Running lights are often tied to the same circuit as the dash lights. Brake lights can be on a different circuit. This means you can have two fuses feeding one bulb, just different filaments in that bulb.

Might pull/check and reinsert the fuses. Corrosion can build up in there and make for bad connections. Not common but cheap to check.

Possible the turn signal switch in the column is bad.

Double check the long connector at the base of the steering column. They can come loose.
