82 Chevy C10 Left side turn signal not working, HELP

[VetteVet]

If you want to bypass the turn signal switch to test if the right turns work then locate the column connector and unplug it. The half that goes to the firewall and to the signal lights has a purple wire and a dark green and a dark blue wire in it. The purple wire is from the turn signal flasher and is hot with the key on.If you run a jumper between the purple wire and the dark blue and the dark green wires and turn the key on, The right side should flash.
