1993 Nissan 300ZX Airbag light on, no radio power and no in

1993 2+2, Recently had a relay replaced to fix my highbeam, cruise control and blinker problem. Currenly my antenna was broken and no longer goes up or down but when I turn vehicle on and off I can hear the motor of the antenna trying to raise and lower. A week ago I pulled into my driveway and when I returned the next morning I didnt hear the antenna trying to raise. I didn't have any radio power, my interior light would not go on and my airbag light is on constantly. Since the last multi problem was repaired by replacing the relay. I am wondering if it is another relay or just a fuse?
