Question: Blower motor resistor bad?

My Haynes manual says I should have continuity between the power terminal and all 3 other terminals on the resistor board, just a different resistance values. I DO have continuity on all 3, but all at the same ohm reading. Do I need a new one, or is the problem most likely the switch. The fan runs when I jumper 12 volts directly to it.

A continuity meter is not the best way to test resistor packs. You should really check for power going in and out of the resistor pack with the circuit live through all the different positions. If if you don't have power to the resistor the switch is probably defective or the power feed. If you have power to the resistor pack, but not coming out, then the pack probably defective.
