You'll need to take it to find out why the light is on... If it's like the e classes there are over a dozen reasons the light could be on, and without knowing the code/reason for the error no one can really make an intelligent guess at how to fix the problem. My money is on Error B1241 - Refrigerant Low... Post back an let us know what's up.

thats the economy mode for the AC controls it really doesn't blow cold cold air mearely keeps the ca a gentle cool. No cold air could be a vacuum solenoid pump that could have sprunt a leak and is now not actualting a lever behind the dash. I had a solenoid fail on the aif recirculation panel which made the car use out side air 100% of the time but not anymore since I replaced the part


there is either low refrigerant level in the ac system also there was a service bulletin for the s classes foe the same complaint u r mentioning theres a fault code stored for the ac refriderant pressure sensor.
