Fan motor quite working, was rwplaced with a new one 9 months ago

Hello, I'd be surprised if the blower motor has failed again, and less surprised to learn the blower motor resistor or relay is failing/has failed. First steps: check the resistor, test the relay, and ensure there is a good ground for the blower motor. If everything checks out, bench test the blower motor.

I undid tje hook up and it started working. Mmmm. Happy for now. Thanks
