The aux fuse blowing has nothing to do with your temp or fuel gauge. That fuse only powers your aux power outlet I would check an see if u have something stuck in there like the tip of a cell phone charger which is common for doing that. On your inop temp and fuel gauge it's probably a bad body control module real common to go bad on that model car. Is anything else inop light your keyless entry or power locks inside lights inop or flashing for no reason. Let me know.
