Yes, this belt has everything to do with the AC. The belt turns the AC compressor. The first thing to do is replace the belt. Then see if everything works again.
It is possible that your AC compressor is bad and that caused the belt to fail. One way you can check this is to try to turn the AC compressor pulley and see if it turns. If it turns easily then it probably didn't cause the belt to fail.
