I have a '01 GMC Yukon. The rear air conditioning works, but when it comes to(rear)heat…I’m out in the cold. Any ideas, if so, where in the vehicle are your ideas located? 🙂

The rear HVAC system has a mode actuator controlled from the main HVAC controls on the dash. This actuator switches between the heat or AC mode. There may be a problem with this actuator.
