First, I understand from various sources that rare excursions into the 100 mark are not uncommon or dangerous. Still, I'd also fret.
I'm no expert but I did have the same problem with my 190. The same circuit protects the AC unit also protects the fan on my car and the fuse was good, BUT the brass prongs that hold thge fuse were corroded slightly. I cleaned them and greased them and the fan works. (Hell, clean 'em all!)
I also replaced the thermostat and noticed that the car ran cooler so the thermo might have been sticking a bit. If this works, it's the cheapest advice of the day!
