gotta be careful with fuses in extreme cold if they're the metal strip/wire type.
the strip/wire is very thin and held firmly at both ends, in extreme cold the metal contracts and can snap (not helped by also becoming brittle) especially the cheap ones, the more expensive ones have a twist in them which means they can stretch further and last better in the cold.
when i stayed in canada we often had to replace vehicle fuses for this very reason.
