Q: Air conditioning not cold enough

Hello. The first step is to connect a scanner and see if there are any codes, and if possible, see what data is available to see if any sensors are out of range. Then a set a gauges should be connected to see what the pressures are in the refrigerant system. If the pressures are low, the system will need to be inspected for leaks. Once all those are checked, a recommendation can then be made. Being that the refrigerant system is under pressure and the engine might need to be running, an inspection should be performed by a mechanic.
