What to do if the high and low pressure sides are too high and the Chery A113 compressor makes exceptional sounds?

If the high pressure side is higher than specified and the low pressure side is also too high, with the air conditioner refrigerating and the compressor making unusual noises, it could be due to excessive refrigerant, a failing expansion valve, or a disabled compressor. First, evacuate some refrigerant. If the refrigerant volume seems normal, replace the expansion valve, refill the system, and retest the pressure. If the refrigerant was obviously excessive, refill to the correct amount and retest. If issues persist, replace the expansion valve, dredge the pipelines, and consider replacing the compressor and fluid reservoir.
