I am confused here. I have all the rear tail lights operating correctly except the passenger side brake light.

-All bulbs are checked and ok.

-Turn signals/hazards work fine.

-Could the socket be bad?

Thanks, GI

What year and model? Is it a 240Z by chance?

Apologies.

-1973 240z MFG date 03/73 with 9 pin light/washer switch.

-It has 3 wires to the bulb:

1=black

2=Green

3=Green/blk stripe

Thanks, GI

Tip - there are so many differences between the various years and models of cars, it is always a good idea to note that in some way when posting. Popular methods include noting it in your profile description, putting it in the auto-signature, or having year and model set as a Custom User Title in your profile settings. These methods all work if you only have one Z.

OK. If the turn signal and hazards work, it's not the socket. I suspect a worn, dirty or broken turn signal switch. On a 240Z, the brake light circuit passes through the switch and that is where it is split into left and right.

Thanks Arne.

-I updated the "About me" section. not sure how to do the Auto-signature yet.

- I will re check the TS as I just bought a guaranteed good used one recently and all worked initially.

Thanks, GI

Now I am almost insane.

-Took both TS switches and cleaned all ther contacts and checked all the wires to make sure they are soldered and in place.

--Now I have the passenger brake light working and no driver side brake light!!! The bridge jump is looking better and better.

Arne I think you were right about the TS switch.

-in checking for continuity between wires we pullud a couple connectors off an 2 wires (green and black) were ever so slightly not locked into place. No we have brake lights!!!

-Thanks for all the help.
