Hello,
I have a 2004 CLK 320, which I purchased used several months ago. I am still getting familiar with some of the controls. I am a bit confused about the A/C OFF button functionality. The owner's manual indicates that hitting this button will turn the A/C compressor off. When I have the cooling system set at a low temperature (it's hot outside), I have both cooling zones set to AUTO, and I hit the A/C OFF switch, it is clear that the compressor is still running and very cold, air conditioned air continues to come out of the vents. The dealer told me that this is normal - that the compressor always runs in this model - this contradicts logic, and the owner's manual. I would assume there is a way to run the cooling system in an economy mode, similar to selecting VENT on older cars. Can someone enlighten me on this issue?
Many thanks,
John
