hemant Posted October 14, 2013 Report Share Posted October 14, 2013 Hi guys ... recently my car's CL 09 AC system is blowing out warm air and someone told me that resetting the AC system might help ..its like a do-it-yourself fix since I am trying to avoid a trip to the dealership. What do you guys think ? Link to comment Share on other sites More sharing options...
jamal Posted October 15, 2013 Report Share Posted October 15, 2013 Yes you can try to reset it but if the AC still blows out warn air you definitely need to take the car in for a check-up ... dont prolong your service trip. Link to comment Share on other sites More sharing options...
saiff Posted October 15, 2013 Report Share Posted October 15, 2013 i have seen all kinds of problems form into AC problems can be anything from the coolant to the refrigerant, electrical issues, leaks, etc. never heard about resetting the AC system. Good luck brother! Eid Mubarak btw Link to comment Share on other sites More sharing options...
mufti Posted October 15, 2013 Report Share Posted October 15, 2013 I know little about CL class but w y don't you access the diagnostic mode on your merc's display and look at the temperature levels of different aspects or pressure levels? I am assuming it might as well have one. Those help establish where the problem is arising from, a leak, compressor problems due to electrical problems and so on and so forth.

duttg Posted October 15, 2013 Report Share Posted October 15, 2013 when I had this kind of a problem I had to look at all of the options and then narrow it down to what i thought was the problem .. eventually the mechanic confirmed that the evaporator sensor needs replacing and so my problem was solved. Hated spending the money out of the blue though. Link to comment Share on other sites More sharing options...
vijays Posted October 15, 2013 Report Share Posted October 15, 2013 Reset AC system: - Insert key, select cylinder 2, this will prevent the engine from cranking - Two buttons you have to focus on, the defrost and the re-circulated air ones. Defrost one has three lines going through it and the other one has a picture of a car with curved line through it. Google you will find them. - Press both these buttons simultaneously and hold them there till the LED lights start flashing. - Wait for them to stop flashing - Turn car off - Wait one entire minute to turn the car on again. Walah! Link to comment Share on other sites More sharing options...
