I have had the same issue with meltdown a while ago and about to do the repairs now. My problem is that after the fuse housing burned, I lost the +12 at the fuse leg, which goes inside the car into a bundle (to the ignition switch?). Has anyone experienced the severage of the +12 connection?

I have been driving the car for six months now without wiper or AC.

For repair of the +12 leg. What would you recommend?
BTW, mine has the cabin filter which may have caused the whole issue as Steve mentioned above. So, I would say replacement of cabin filter is a good maintenance item to keep.
