1993 Jeep YJ

Electrical problem
1993 Jeep YJ 6 cyl Four Wheel Drive Manual 148200 miles

i have no power to the accessory plug on the left side nor to any of the 3 fuses along the bottom of the fuse box. All of the fuses are good. The affected item include the heater fan, radio, and accessories(driving lights and axillary plug for my XM radio receiver). These items work fine when rigged with a jumper, so I don't believe there are any shorts or other problems with these components. All lights, signals, wipers etc. Work. The large fuses under the hood have all been checked also, they are good. Any help would be greatly appreciated.
