I have a 1975 Vette that is having issues with the blinker. Both rear blinkers work and so do the flashers. But when I pull the headlight switch my driver's side rear doesn't work. Light on the dash for the blinker comes on as well. I have changed the blinker relay thinking that was the issue, but it wasn't. Don't know if I have a wiring issue or it's something simple. Just looking to get pointed in the right direction on what to look for with trying to figure this out. Any help is appreciated, thanks!
It will be a ground issue. When something likes this happens it is searching for a ground thru some other bulb or source. I would take apart the grounds for rear and headlight switch clean down to see good clean including eye and bolt reinstall and try again
The rear taillight bulb is good. I tried the other side that is working in the driver's side to verify. I also have replaced the headlight switch thinking that could've been there cause.
The ground for headlight switch is on righ hand pillar way up and ground for rear lights is on frame by rear tire carrier I believe. Take these apart and clean up good down to metal and check eye and reinstall
