Cancel that question. With some more testing I've figured it out.

The failure was happening because on setting 1 the fan motor was stalling and drawing too much current as a result. The resistor pack overheats and the thermal fuse blows.

I'm going to put a post into the guide section under punto mk2 for my fix which I just tested on my Punto, so apologies for the interruption to your thread!
