Inline Fuse

Wondering If someone can help me, i have upgraded my stereo in my 2001 sirion i assume it blew a fuse as it didnt work through the radio harness and had to be powered from a different source, issue i have now is my AC fan does not work. i have checked all the fuses under the dash and in the engine compartment and replaced them all and still no luck. does anyone know if there is another inline fuse of fuse box i should look at

Thanks Frustrated as hell

Have you tried measuring for current on each side of the represented fuse? If the air conditioner wasn’t installed at the factory, only then could an inline fuse have been added. Otherwise, it isn’t Daihatsu’s standard practice of hiding fuses
