Brake light and turn signals stop working at the same time

HI ALL,

I was driving my 69 2000 today on a Beautiful Colorado day, at first everything was fine. Then I notice when making a left turn the blinker was not blinking. First I figured the bulb burnt out, so I turned the right side signal and again it didn't blink either. Then when braking I noticed the AMP Meter wasn't moving when I pump my brakes. So I drove the car back home and all the bulbs, fuses wiring connection were fine. It been awhile since I restored my car and the Electronic wiring memory is not there. So my question is, what would cause both turn signal and brakes lights to fail at the same Time? Is there a Terminal / Switch connection that I need to check, that may of failed and needs replacement that controls these two functions? I looked at the electrical Diagram and its above my pay grade.

Any help is appreciated and thanks to all.

Bob

Did you check the voltage going to the fuses?

There is a chassis ground wire located underneath the LHS tail lights, check the integrity of him.
If your car has a hazard switch, I'd "hazard" a guess that might be causing the indicator issue.
Check the wiring to it and give the switch innards a birthday by spraying a generous dose of contact cleaner into it.

Do your hazard lights work? From the drawing you see how everything routes through the hazard switch.

Thanks to all,

I will check out each of the suggestion given me. I've been having loose wire connection issues on my Hazard Lights and that may be the problem. Hopefully it's that simple.

Thank you all for your suggestions.

This is great timing. Same thing happened here. No brake lights or turn signals.

But Hazards DO work.

Excellent wiring diagram. Let the hunting begin…

I just noticed, my horn stopped working at the same time. Coincidence?
