Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, welcome to Just Answer. My name is***** am assuming that the fan is blowing but you are not getting any cold air. A low refrigerant charge is the most common cause of this problem. You will need to have the refrigerant level checked by evacuating and recharging the system and then you will need to have the fault codes in the climate control system erased in order to reactivate the compressor. A faulty temperature sensor in the system could also cause the problem but low refrigerant is the most common problem.
Let me know if you have any questions.
