Q: The heater stopped working in my car. Switches and blower are fine. No heat. on 2006 Pontiac Torrent

I have a 2006 Torrent that the heater does not work. The blower fan and all the switches are fine. Airflow will change from vent to floor to defrosters.
When i turn the temp knob to hot air, only cold comes out. Does not matter what setting the mode door is in.
I have read that it could be the temperature door motor is bad and needs to be replaced.
My mechanic has not done this.
Can we do it in our garage.
