So I just got this awesome Volvo wagon and the blower motor was shot, or so I thought. I pulled the motor, I tested it, and it worked. I also tested the resistor and all three speeds work as well. So, happy I didn't need to buy any new parts, I put the motor and resistor back in and hooked everything back up, but it still isn't kickin' on! I don't know if the selector switch is bad, or how to test it? Maybe it's not getting power for some reason? Pleas help, I want to get this thing working and get my wagon's guts back in'er!

Thanks
