1996 Sable Fan

Wondering what the problem might be. I was just out driving my car, and it worked fine, including the a/c. Everything seemed to be fine. Then I went into the store for a bit, came back out, turned everything on as usual, but the fan won't come on. Tried a/c, vent, heat......no fan. I didn't notice anything else electrical NOT working, although I heard nothing else turn on when I tried the a/c and heater switches.

Could this be a fuse, or am I looking at replacing a fan motor? If it is a fuse, where do I find it, in the fuse box under the dash?

Thanks.

There is a thermal fuse on the set of resistors that control the fan speed, that may have burnt out. (The fan speed switch routes power down to this little resistor bank).

There is a cabin air filter that needs to be changed, so that airflow can keep this resistor bank cool. It's mentioned in the owner's manual, it's called the Micron-Aire filter or something like that.
