Brake / Backup Lights problem is driving me crazy. Advice needed.
My brake, backup, license, and hazard flashers do not work. All other lights worke fine.
Fuse is good.
Bulbs are good.
New brake switch.
New Backup switch.
On the bulb end, all wires seem to be hooked up ok.
Any assistance and advice is much appreciated.

Make sure you have a ground......In my 72 its grounded to the driver side frame rail off of the rear main harness.

it's grounded.
Do you think the hazards not working has anything to do with it?

You need to troubleshoot it methodically. Start with the rear license plate light. When the lights are on, do you have voltage at the bulb? If so, then it's a grounding issue. If not, then start tracing the wiring back to the light switch.
Same goes for the other lights. Start at the bulb and test for voltage. If there is +12v then the problem is with the ground, otherwise you have to backtrack and debug from there. Starting in the middle or just randomly checking different pieces/places in the circuit is not the way to troubleshoot an electrical problem.
Post back with the findings when you check for voltage at the bulbs, and we'll help you through it. Good luck!
