Yes, I am referring to the air conditioning brought into the hybrid battery via the coolant lines you can see on the underside of your vehicle especially near the rear driver's side wheel. i called it rear a/c. Coolant line get cold when i turned off front a/c and cools down battery. when i turn on a/c coolant line get warm and no cold air for battery. that is why i want to use cabin air to cool battery just like 2010 models.
