Could a bad resistor completely shut down the blower?

I'd jump fire to the blower hot wire and another wire to ground the case just to confirm or deny that the motor itself is OK then start checking continuities for the open live every 24 hour block of time like it's your last day on earth

Less noise in the electrical system when you switch the ground. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

You may have had an open resister winding taking out one or two speeds and then the thermal unit may have finally went out and stopped all blower motor opperation. Ron
