Have Mercedes Questions? Ask a Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question
Ok, so at this point, neither the heater or the ac is working?
Does this mean that the climate control fan is not coming on at all no matter the speed setting, or that it is blowing air, just lukewarm.
Please remember that I am not there and therefore rely on as much detail as possible from you and at times may need to ask for more information
