[QUOTE="dzeisen, post: 415951, member: 4329"] How to check if the compressor is not engaged? I totally switch off the entire aircond by turning off the blower until the light on the aircond display goes off. I can't confirm that it is from the engine or from the dash although my ears seemed to pick up as if it's coming from the engine. Probable reason is when I slowly press the pedal, the sound becomes wooooo, wooooo, wooooo.... It somehow is in sync with me pressing the pedal. If I let go the pedal, the sound also wooooo, woooo, woooo... Aih... =( [/QUOTE]
