My first inclination would be opposite, that it just might be the fuse. Maybe it was sized for 'normal operation' which would be just one or two windows at a time and doubling that current draw (all 4 windows at once, which is a pretty unusual scenario) was maybe a bit too much for it??
Anyway, that's the first place I would look - When something isn't working, try the simplest solution and work from there
