Air Conditioning Not Cold on Mercedes-Benz ML55 AMG

Problem Description and Possible Solution

AC system leaks and/or a faulty evaporator temperature sensor can cause poor AC cooling. The failed sensor can prevent the AC compressor from coming on. Leaks cause a low refrigerant level, which reduces the ability to cool.
