Defrost only is a general fail-safe mode for the system... could be the temp selector wheel, the pushbutton panel, or the amplifer unit as well. A quick check for the servo is to listen carefully (from outside the car) when you switch off the key, as the servo goes to its 'park' position when the main power is off. It's a whirring and sometimes clicking sound. If it does not do anything, then it's done. Mac
