Thought it might be a ground problem so reworked all the grounds. Again it helped the brightness of the tailights and turn signals but was no help on the brakelights or hazards. Great suggestion though!

I have already tried a couple of different hazard switches. I own a 71 Z also and my stepson owns a 72. It appears that the issue is still in the combi switch somehow as I get no power to the hazard switch at all. That is with key on or off. AS I understand the wiring diagrams I should have power to the hazard switch. I already replaced both the turn signal and hazard flashers. I will do some more tacing tomorrow but I haven't found anything so far in tracing the wires. I appreciate your thoughts. Thanks

Sorry should have said in post turn signals work great. Just adds to my frustration! Tirn signal switch is brand new from British Victoria here in Kansas City. It helped lights considerably.

I've already searched this on several sites. My 73 has no brake lights. I have replaced all the fuses and replaced boththe headlight and turn signal switches. Headlights and tailights work great and are super bright (for a Z) but still no brakelights. I have also replaced the brake light switch which was fried closed and it works fine. Should their be any voltage at this switch? I have chased wires until I'm totally frustrated. This car has sat for 15 years and I am in the process of resurrecting it. So the brakelights have never worked while I had it. Hazards don't work eaither!! I'm open to any ideas.
