My left side brake light is not working. Good bulbs, good fuse, like new bulb harness. The parking light works on that side as does the turn signal, but no brake light. My car is a 73 240Z.

It's probably the turn signal switch.

I'm two hours away if you want a definitive diagnosis.

It would be unusual for there to be an issue with the turn signal after Dave reconditioned it, but it is not impossible. The turn signal is the point where the brake light circuit and turn signal circuit meet that could cause the issue that you describe. 

Fortunately a meter and knowledge of the circuits can give us a more definitive answer.

I will check next time I'm off work. I work 3rd

Thanks for the reply. I was wondering what color your car was because I saw a Z the other day on the south end of Woodruff rd but it was orangish...
