1993 Ford F150 blower motor help

For about a year, my blower has only been working on high. Did some research, which led me to beleive it was the blower motor resistor. Before i gota a chance to change the resisitor, the blower stopped working altogether, wouldnt even blow on high. I had the resistor, which I changed, but the blower motor still doesnt work. Should I be looking at the pigtail that attaches to the resistor, or is the entire blower shot?

Thanks
