A quick question before I go get broke, lol. On my 2002 S500 the AC off button stays in the illuminated position no matter what I do, thus the AC is not blowing cold. Is there a quick fix for this or do I need to get it hooked up to the computer at the dealer and possibly recharged? Thanks in advance

 

sounds like run out of AC GAS,yes it as to be pluged on the scanner or on MB DIGNOSTIC TO READ AND ERASE BEFORE FILLING THE AC GAS,AFTER ERASE DO NOT USE AC OR FAN DUE TO LIGHT WILL COME BACK ON ,AFTER FILLED GAS CAN BE USED.........
