This one has me stumped.

Left front blinker doesn't work, I get the fast blink so the BCM knows there's not enough load on the circuit.

Left Mirror signal and rear signal both work
Bulb is good
wiring harness on the headlamp is good (plugged left headlight assembly into right side of truck and all functioned properly)
double checked fuses
tested for continuity from headlight plug all the way back to the fuse box all wires are good.

any suggestions?
