The rear AC operates as follows..
The auxiliary climate control system has dual controls for the front and rear passengers consisting of temperature/mode and blower speed. The front auxiliary A/C control functionality is integrated into the main instrument panel mounted HVAC module. The rear auxiliary A/C control is mounted in the rear finish panel of the front floor console. Temperature and airflow mode are combined into a single setting. When the temperature is set to full cool, the airflow mode will be automatically set to discharge from the headliner registers. When the temperature is set to full warm, the airflow mode will be set to discharge from the floor register.
What other issues are you having with the system?
