1967 Camaro RS turn signal/ 4 way flashers/brake lights
« on: October 27, 2019, 04:20:27 AM »
Hello, having an issue with my turn signals, four way flashers and brake lights. They did work a few months ago. The running lights function properly. I've checked all bulbs individually with a power source and they are good, not surprising, as running lights work.
At the harness under the steering column I have power at the grey wire (column shift indicator light) when lights are on. CORRECT. I have power at the black wire (horn), when grounded horn works. CORRECT. I have power at the purple wire (with ignition on) power from hazard signal flasher. I have power at the brown wire (with ignition on) power from turn signal flasher. I have no power at dark green (rr turn signal) or yellow (lr turn signal) dark blue (rf turn signal) or light blue (lf turn signal). I do have power at the white wire when I press the brake pedal (power from brake light switch). CORRECT.
Any ideas on where to go next?

I did more investigation by disassembling the steering column to reveal the switch. If I manually use power at each connection at the switch I can make the turn signals work. So I'm leaning towards the 4 way flasher portion of the turn signal switch being faulty. Any thoughts?

Is there power coming into the switch?  You are putting power on the downstream (after) side of the switch and the lights work? But just activating the switch, the lights don't work even though there is power upstream?
If all are yes, then the switch appears to be bad.
