Engine on. Left blinker works fine with headlight switch in all positions

Flashers are fine

Check your grounds.

Make sure your wires are in good shape. Look for damaged/frayed or bare wires.

Also, do you have a rely on the front lights?

All light bulbs to LEDs. LED have very low resistance. Don't create enough load on bimetal turn signal flasher. One way to correct this is use an electronic turn signal flash unit. Uses a " brain" to time turn signal. That's based on your wiring and grounds and such are all good.
Also LED bulbs only flow voltage one direction, diode is like a check valve, you may have found that out already. Hope this helps.

Funny how we talked exactly about this today with a friend,who's Firebird's tail lights are so poor,that I suggested LEDs. Coincidence? Matrix lol
