"What's the problem?" here ya go:
When the rear AC is turned on, the front ac loses 50% of its airflow. Also the system acts as if its possessed. The airflow just changes randomly...turns warm, air stops flowing from side vents, flow surges, blower volume is at least 200% louder, etc.. I have to lower the auto setting 9 degrees to stay somewhat cool.
As long as I keep the rear air turned off the system works great. I can set the auto at 78 degrees and I stay cold...but as soon as I turn on the rear air the ac is a POS! and the cabin does not STAY cool.
mine is at the dealer now for this issue.
