Last week the A/C fans on my 2004 Honda Accord LX failed. It wasn't quite all at once... the fans kicked in once or twice after the initial failure, but cut out again after a couple of minutes. After doing some research on the relevant bits (fuse under the hood, blower resistor, blower motor), I took a multimeter out to do some diagnosis.
The first measurement I made was to the pins of the power connector right at the blower motor. I unplugged it, turned the car accessory power on, turned the fan control on, and took a voltage measurement across the wires of the connector: 12V.
Is that sufficient to conclude that the issue is the blower motor itself? The only reason I hesitate is that most of the diagnosis articles/videos I've seen use a more purpose-built probe, such as this. I'm not sure if the resistor complicates the circuit in a way that might render a simple multimeter voltage reading at the motor insufficient. Is there anything else I should check before deeming the motor faulty?
