You can runs leads from the blower fan terminals to the negative and positive battery post to check the fan. It's not impossible to get a bad part. Since you verified power at the harness connector, run the test light inline between the two terminals of the connector and see if it lights; if it does, you'll know you have ground and I would then suspect a faulty blower motor. Make sure you check in multiple fan positions. Also, if you have manual A/C, you'll have a blower resistor, but, if you have AUTO A/C, you will have a fan blower amp, instead.
