I just noticed that my A/C clutch is energized as soon as I turn on my ignition and does not turn off when the "ECON" or "0" buttons are pressed on the Climate control panel.
Are there any relays that could be fused closed that I can check or do I have to repair/replace the Climate Control module?

Thanks in Advance for your help.
