the blower motor should make a sound like a bearing going out if it was to that stage, and the reason it works on high is that its a straight connection , as in FULL voltage. the resistor is needed to reduce the voltage, therefore making the motor spin slower, and they get pretty hot in the process, so it needs to be in the path of air flow.

I know the same thing happened to me in my old ranger, and it was the resistor.

you SHOULD get voltage at the harness on all settings, its the output to the blower motor that is fed through the resistor itself. (except on max) <img src="/forums/images/graemlins/butwiggle.gif" alt="" />
