It walks through pulling the compressor, measuring and replacing PAG oil, swapping in an aftermarket Denso-type compressor (around $220 versus a costlier Kubota clutch), installing a new dryer, and recharging refrigerant, though the real fix turns out to be a faulty switch, not the compressor. Useful for owners troubleshooting AC issues themselves.
