Default 1986 - A/C blower

Driving over to the East coast yesterday my blower motor quit. I have a manual A/C - heater system. In reading the owners manual there is no mention of a fuse. What am I overlooking?

There is also a resistor on the top side of the blower housing under the hood that controls speed

Blower gets power from 25 amp AC fuse, for all speeds except full speed. Full speed gets power from a fusible link to battery.

You can diagnose using this info from my 86 FSM
