Fiat electrics - two faults, are they related?

My Fiat Punto has been into the garage to have its failed heating/ventilation fan replaced, so that I could de-mist the windscreen again. After two days, it stopped working again, and now I've had to have the loom replaced.

Could the mis-functioning fan cause the loom to burn out? Are these two faults connected or just coincidence?

They could be connected, particularly if the wrong fuse has been fitted.

Better than the original Punto in almost every way. Excellent driving environment. Easy to get in and out of. Practical and inexpensive to run.
