1999 Ford Mustang Electrical Problems

I have a 99 mustang 3.8L v6. The other day i notice a few things stopped working. The radiator fan will not kick on, the ac blower wont work, the turn signals wont work but the flashers will, the defrost wont work, and the reverse lights will not work. I have checked to make sure that all the fuses where ok and they all seem to be good inside the car and under the hood. I have a feeling that they are all on the same fuse i just cant seem to figure out which one. They all quit at the same time. I also have the airbag light on. If anyone can help i would really appreciate it.
Thanks
