 Wow, that is terrible Last time i faced one problem like this too... i changed the AC control unit and everything works fine, and don't forget to check the evaporator temp sensor first !!! i may cause the problems too! Enjoy Diagnosis www.mercedesbenzone.com |

S500,AAC gives problems very rarely that the a/c control unit gets problem... and very often the evap temp sensor to get his problem because of moisture. it's just the evap temp sensor. better replace the refrigirant temp sensor as well. |
