Red face Brake Light

O.k., so I got the tail light working (after messing up on the ground).

But the whole reason I replaced the thing is because the brake light wasen't working! (the tail light was before)

So why might the brake light, on one side, not work??

So you think the problem (again, the tail light works, but the brake light dosen't) resides within the tail/brake light assembly?

So why would the tail light, but not brake light, work?

you have two contacts in the socket one for the brakelight circuit and one for the tail light circuit, one side could be bad. another possibility is this, in my car the wire harness for the rear lights uses a ribbon type connector that runs from under the dash to behind the rear seat the dash connector in my car is in rough shape i have a c-clamp holding it together the ribbon looks just like the ribbon wire you see in a computer. from what i can find so far you cant get a replacement for it so i would have to cut each wire seperatly and build a hole new harness from the dash to the rear deck. i dont know if you have the same type of connector for sure but our cars are the same year so they probably do. again you can unplug the connector and make sure the contacts are clean.

Thanks for the reply.

I'm lucky enough (at least practically, maybe not aesthetically!) to have nearly all of the wires underneath the steering wheel and instruments exposed.

So I can make out a mechanism that probably sends a signal from the brake pedal to the tail lights. Is it possible, you think, to make out which wire eventually leads to the brake/tail light? My wiring diagram seems to show only one wire leading representing brake and tail lights.

it's probably easier to follow the wire from the socket back to the dash there is probably one wire that feeds both sides and then its spliced in the trunk. trace the wire to the trunk connector and then find the matching color wire under the dash, in my car the harness goes right under the drivers seat.

But if there is one wire leading to a connector in the trunk (I suspect you're right here) wouldn't it then suggest that the flaw lies within the trunk area?

(remember that one brake light works)

Thanks for your very helpful responses!

Howdy

Al here with AutoReWire.com.

I'm assuming that you are working on a '62 Chevy.

I am also assuming that you tested the contact at the taillight bulb with the test light and have no power when the brake is depressed or when the left turn signal is activated. If you haven't do so. If you have and there is no power

Go to the steering column and test the Black w/Yellow (or could be solid Yellow) wire coming out of the column. Depress the brake and the light should light. Turn on the left turn signal (with the key on) and it should blink.

If you have power coming out of the column your problem is in the wiring harness to the rear of the car.

If you have no power coming out of the column you have a problem with the turn signal switch or the attachment of the wire at the switch. Many times they brake off where they are soldered to the switch.

You're saying that, even though the turn signal works, its switch is ka'put?

I don't understand why that would be the case.

66chey2ss autorewire is right about the turn signal switch if you have no power at the yellow wire at the steering colume. I had a simialar problem with a 95 chev luminia car last week , turn signals worked , park lights worked,hazzard lights and 3rd brake light worked. depressed the brake pedel and checked the yellow and green wires for power, nothing. replaced turn signal switch , now all the brake lights work.

I guess I'll have to pull the steering wheel, then. The switch is where the lever attaches in the steering column, right?

That would be correct.

Good luck and let us know the outcome.
