In this video I show you how to reset the Mercedes-Benz air conditioning system in order to work again.
Anytime you have a flashing light or a solid EC or ac off button it means there is most likely low charge and the ac compressor is locked out from working. The only way to fix it, is to check the charge and erase the code.
I hope this helps.
