Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** is typically caused by a programming issue in the HVAC module. Most of the time the dealer can just reprogram it and that will take care of the issue. I have seen some of these need a new module, but that is not too common. I know the dealer does not usually want to do this unless they see a problem so the fact that it is intermittent does not help. If you need further assistance please let me know.
