The resistor is at the ground end, and is NOT the power supply. If you have a bad fuse, bad switch, cut wire, etc. you will have no power at the resistor.
Check the heater fuse for 12V. If good, connect the power lead on the blower to 12V, and the ground lead to ground. If it runs, reconnect the power lead, and check for 12V into the heater blower switch. If that's good, check for 12V to the resistor. Many things can go wrong. The whole thing could be perfect, and if the ground wire at the resistor is unplugged, the blower won't work.
Amateur restorer. Well, sometimes I have been paid for it. But not right now.
