Running light problems

[Skipper T]

New to me - 1972 FJ. I just discovered that the flashers, turn signals, brake lights and horn are all dead. I havent had time to dig under the dash yet, but who's my most likely red-headed stepchild?

Could be the power going to the fuse block or the block being the culprit…

I would have to check but I think most of them are on the top of the block that get supplied same input power

Everything else works?

Cranks and starts ?

The fuse block could just need a good cleaning with fine grit… check the fuses as well … test them … done just do a visual

+1 for actual testing the fuses - they can look good but be bad.
Disconnect the battery ground, take a bent 30 cal bore brush to the fuse contacts. If that doesn't work, could be corrosion on the back side of the fuse block.
