So if the fuses are intact, my meter is showing ample voltage at the blower power connector and the motor spins when hardwired to the battery, what else might be the problem? I see by looking at the wire diagram provided that it looks as though a relay might be involved with the blower power. But if the relay is bad, wouldn't it not give ample voltage at the connector? Still cold in CO...

 

If I were diagnosing this myself, my next step would be to jumper between the plug and the motor to see if it runs. This would just be to verify the plug connections are tight and working properly. Next, I'd be looking at amperage coming from the plug to verify it is a strong voltage.

 

Check your ground for the fan. If a bad conection, you will have some volts, but not enough amps to turn motor. Takes both of them to make power ( P = IE). It is C910, pix attached. Are you getting good voltage with the fan plugged in? Might have to back probe the connector.

 

...wish that guy documented his fix. this is where i'm at.
