Tried to put in a second AC in my 2014 and was told it was prewired, and there is a breaker for it. Upon looking through the return vents with an endoscope, there is no framing for it. It would be a costly installation. Looking into the AC ducts the same way, there are ducts coming form the location where it should go. The dealer and I gave up.
