Poor cooling from the air conditioning may be caused be leaks from the AC cooling lines at the AC compressor. Inspection of the system is recommended to isolate any potential leak.
The air conditioning expansion valve can fail causing poor, or no cooling from the AC system.
The AC evaporator can leak causing poor cooling of the air conditioning. The loss of refrigerant may be hard to diagnose.
