Blower vents emit warm air when A/C is turned on

Q: How to fix Blower vents emit warm air when A/C is turned on in Ford RANGER?

Due to thermal expansion and abrasion of the friction linings, the so-called air gap of the clutch exceeds critical values and the coil does not have the strength to fasten the system. The solution is not to replace the compressor, but to dismantle the front pressure panel and remove some of the spacers (shims) so that the gap returns to the factory size.
