77 sedan rear lights

[Rust]

Thanxs to this web site I downloaded the wiring diagram. I have checked all wires fuses and connections.....but still haven't located the problem.

 

Both rear lights(including brake lights) and licence plate lights are still not working.

 

Can Anyone shed some light on this (Pun intended):-\

I'm no expert, but I am trying to build up my thread count. Since you've already checked the fuses, my next step would be to pull the light housings off and really look over all the connections. I'd clean them all and maybe use a dab of dielectric grease as I put them together. Since everything back there is dead, I'd be suspicious of them all being grounded at the same point and it's loose or fell off.

 

If that doesn't fix it, you'll probably be starting at the fuse box and working your way through the circuit with a test light. I say check all the connections at the back first, cause if you start with the test light and find the problem up front, you'll never bother to clean the connections at the back.

I'm thinking the problem is somewhere up front. Used a test light out back. I am hoping someone has had a simmilar problem w/ a gen 1 car and knows the fix before I have to start ripping up the dash and testing the wires in there.
