Air conditioning stopped cooling / no response to AC button

Q: How to fix Air conditioning stopped cooling / no response to AC button in Ford ECOSPORT?

Even though current reaches the electromagnetic clutch coil, the air conditioning compressor does not turn on. The diagnosis indicates excessive natural friction wear of the surface of the clutch disc and pulley, which results in the formation of too large an air gap. The magnetic field has no force to attract the target. Solution (cheap repair method used by mechanics): Dismantling the clutch disc from the compressor axis and removing one thin spacer (shim) from the shaft, which reduces the gap to the desired size and permanently eliminates the problem.
