You said you have 13volts at the blower motor...ok, then it seems its a ground issue. The motor gets the ground signal from the blower motor switch through the resistor...is what I see...and blk #31 is the ground wire. So in actual fact the speed is controlled through the resistor and ground operates the blower...not power.So there should be power at the blower all the time...and when you turn the switch ground is fed through the resister to the blower motor...I could be wrong...but thats what I see.
