I also had the same problem. a/c system on mercedez s class is very sensitive, you must discharge the old freon and use new freon as specify on the manual, and precise pressure : 14 bars. you may find the specification under the hood. if the pressure go under 13 bars, the compressor will automatically shut off, and the red light on the EC button will be on.

this is the probleme with luxury cars ...the venting systheme works with vacum and some thime smal electris motor ...if one is broken or a hose craked ...this kind of stuff appens not much to do but to take the under dash apart and look for the problem, it could also just need a little lubrification on all the moving parts !

Press the O button to shut it off or any other button. Usually when the E/C sticks on its an A/C charge or sensor issue so check that also.

Testimonial: "Thanks....Will see if that works"
The pulley on the air condition has to turn it has a belt on it. The Compressor engages to pre cool the evaporator. Most likely you have a blend door pod leak or leak in the hose or the sampler valve is bad. I would replace the sampling valve behind the glove box/air bag. As that reads the cabin temp and if it thinks the car is cold the heat will stay on because everything is automatic. All vents will blow cold when it thinks its hot and in addition to floor and corner dash center vents will blow cold when it works. If the direction of air is correct then the A/C system may have a leak or need a charge of freon.
