The light for the fan/temp controls is part of the dash board illumination, it is not connected to the same power is the fan and vacuum solinoid controls. Even though the fuse isn't blown, don't stop looking around the fuse box. The fan fuse usually overheats and burns through the fuse box cover. Is your fuse box cover burned, bent, melted? This would be a sign of previous problems. If a fuse has overheated previously then the contacts in the box have probably suffered damage. Check to see if you even have power at this fuse. If so, then start at the other end. Apply power directly to the motor and see if that works, then work your way through all the relays and connectors.
