specific wiring to check would be the single wire na nakaconnect sa A/C compressor (baka nakalas). Then sa center console, yung wires naman na nakaconnect sa A/C switch and A/C thermostat control. All these 3 wires will control the activation of the A/C compressor.

Most A/C will not have a fuse but rather a circuit breaker so I doubt if it was a fuse problem.
