Once again I'm needing your help. '56 victoria, Auto, 292, no backup lights. Was completely rewired last year with new sockets..everything. Now the turn signals and taillights work on both sides and until recently the brake lights worked. Now the right rear brake lite won't work the taillights and turn signals still work on both sides,the the one (right) brake light won't work...socket is new and have changed bulb with same result...any help would be appreciated. Thank. Jim Dahl, Washington Ia

No the brake light switch wasn't replaced, the turn signal switch wasn't either.

Rono has you on the right track. On Fords the brake and signal current is carried on the same conductor so if your signal lights are working then the bulbs, rear sockets and wires are ok. The most likely problem as Rono has alluded to is a failed brake light switch, brake light switch connection, or the circuit leading to the brake light switch. If that circuit is fused check the fuse. The brake light switch that is mounted in the brake line just behind the master cylinder. These switches are alleged to be prone to failure especially if modern high powered bulbs are used. I prefer to do away with that switch and use a pedal activated switch. Since on my vehicles I have added power brakes I use a late model F150 switch which installs in the brake pedal linkage. The brake current is also fed through the signal light switch in your steering column so a problem with the switch or the circuit leading to it could be a problem. I assume that when you rewired the vehicle you used a Ford harness or if an after market harness was used it was wired according to the Ford wiring diagram.
Good luck.

We're heading down the wrong path here. If the left brake light works then the brake light switch is OK. Since both turn signals work, the wiring and bulbs are OK. What is happening is that the turn signal switch is not making contact to the right side when it is supposed to be in the centered position. This can be a bad contact in the turn signal switch, or it is not physically returning to exact center.

I agree with john and bill. Drove myself nuts chasing same problem, and finally figured out it was turn signal sw. New sw and all is well!

Count me in on Johns diag. Just fixed a 72 F model truck with the same problem.

Is installing a new switch something that someone with very limited electrical and mechincal ability can do...find a new switch isn't hard found the at Mac's, Concours, plus others but just wondering if theres anything to beware of ...Thanks again. You probably don't really realize how many pages are in my "notebook" from this forum that I refer back to and how much help you guys are. I check this site everyday and sometimes more.

When changing the switch change one wire at a time from the block. They are easy to cross up and can be a real headache to straighten. My parking lights still come on when I push on the brake and hours of wire switching has never cured it! Chuck

Don't want to seem a smartass, but your problem is easy fixed. The output from the turn signal switch has two circuits per side. The wires for the rear brake lights and rear flashers connect to the circuit going to the rear. You have it hooked up as the circuit going to the front. Just swap the wires on the harness side of the plugs that are both on with the turn signal on. You should have at least four connectors. On my 55 and Oz 58 this group of plugs is just under the dash by the ignition switch.
I hope I have explained it well enough.
Regards

Just read my post and it may confuse. There are four plugs that the harness lights connect to. Two per side - right or left.

I've moved the wires around until my fingers were numb. I'm afraid I would need a picture or diagram to figure it out. Chuck

Hopefully this diagram makes it easier to understand.

From that diagram you would need to swap the white/ blue tracer with the orange/blue tracer position and then also swap the green/white tracer with the green/orange tracer.

I was waiting for the light bulb to go on for someone....It's very well possible there is a bad ground connection between the tail light body and socket.....If this was a'57 ford or '57 t-bird this would be my first bet.... Best Regards, Jeff

Guys....thanks for all the help and ideas. I've added them to my "scrapbook" for future reference. You won't beleive this....it was the BULB. I replace it with a new one, still wouldn't work, so decided it was something else and settled on the turn signal switch which you were very helpful. Before I ordered a new switch I decided to try another new bulb and everything works great. Unbeliveable...again THANKS for all your help. Jim
