ATTN: Wiring GURUS. – 1 turn signal not working.

I have 70 Barracuda and the LEFT front turn signal does not blink. ALL parking lights work, both left and right, including the non-blinking front. Rear lights all work including both blinkers and brakes too. I have installed 2 new bulbs in the left front signal, and still won't blink. When I have rear tail light blinker 1157 bulb OUT of its socket, I only get a soft glow from dash indicator. When I reinstall the rear bulb, the dash blinks fine and so does the rear, but not the front...
