low refrigerant charge, the computer cannot keep the whole vehicle cold with the charge in the system, but its pretty smart, so when the refrigerant pressure goes below a certain value, it tries only to keep the driver of the vehicle comfortable. so the refrigerant system has a leak and its low on refrigerant.
