Hello.
Just wondering if any of you had any ideas of what I could check in troubleshooting my signal light issue.

Right side flashes normal but left side flashes fast. It only does it when the headlights are on (high or low). if the lights are off or just marker lights are on it all works fine. All lights, including LEDs are working fine. I have tried checking connections and just because it's easy I replaced the flasher with no change.

I don't have a wiring diagram which would probably help but I'll look for one later.

Any assistance would be greatly appreciated.

Thanks much
