brother, the fuse for AC is the MGC one only, the magnetic clutch. if fuse and relay is fine, then check with some electrician, maybe some wire is broken, or you dont have gas in AC bottle,
some passo owner here on PW came accross an issue that its aC gas was leaked, and magnetic clutch is not turning on, when he refilled the gas, it started working.
the A/C fuse i guess (but not confirmed) is for some optional electric compressor.
