Need better info.
when shut off no start batt dead and ignition fuse in bjb replace fuse and still no start or crank no power to cluster cluster dead on commute back ????????? What about ignition fuse ? It was blown an you replaced it or you just replaced it ???? When you shut it off no restart ,the battery was dead ? Test battery , battery cable connections , charging system - is it charging ?
First off your probably unaware of how this vehicle works , This vehicle is powered up by the BCM turning on relays an sending commands over the serial data bus (network) ,do you know what that is ? The ignition switch is a low voltage input to the BCM .
Circuit Description (Key Start)
For ignition switch power modes refer to Body Control System Description and Operation . When the ignition switch is placed in the Start position a discrete signal is supplied to the body control module (BCM) notifying it that the ignition is in the Start position. The BCM then sends a message to the powertrain control module (PCM)/engine control module (ECM) notifying it that CRANK has been requested. At the same time the BCM is supplying 12 volts for the IGN 1 relay closing it and supplying battery positive voltage for the crank relay coil. The PCM/ECM verifies that the transmission is in Park or Neutral. If it is, the PCM/ECM grounds the control circuit of the crank relay. When this occurs battery positive voltage is supplied through the switch side of the crank relay to the S terminal of the starter solenoid.

Check the Ignition 1 relay -
Relay Controlled Power Mode
The body control module (BCM) uses the discrete ignition switch inputs ignition 1, ignition 3 and crank to distinguish the correct power mode. Once the BCM has determined the power mode selected by the vehicle operator it will energize the Ignition relay, Run relay and retained accessory power (RAP) relay, depending on which power mode is selected.
Ignition 1 Relay
The relay uses a Hot At All Times B+ power source derived from the underhood electrical center. The ignition 1 relay supplies a power signal to the following circuits when the Run or Crank power mode is selected:
• AC clutch relay
• ABS STG angle sensor
• Antilock brake system (ABS) yaw sensor
• Auxiliary power drop connector
• Crank relay
• Cruse control switch
• Electronic brake control module (EBCM)
• Engine control module (ECM)
• HVAC module
• Ignition control module (ICM)
• Instrument panel cluster (IPC)
• Sensing and diagnostic module (SDM)
• Transmission solenoid circuit

Are you sure it's the fog lights and not the daydriving lights? Nowadays new vehicles have daydriving lights on by default and can't be turned off. However, if you never had this problem before on this particular car, then please open the doors, open the hood and remove the lines from the battery, leave them off for a few minutes and put them back on.

Usually the engine will run poorly, your fuel consumption will be higher than normal and if they are really bad you might get misfiring on the engine. Changing them isn't difficult and the plugs don't cost a lot. Old filters can also give similar symptoms.
If your worried I would suggest you give the car a major service. This covers all the filters, (fuel, air, oil), fresh oil and a full set of spark plugs.

there are a few things that could cause this, is the cooling system full ? is there an airlock in the cooling system ? water pump may not be working or not working efficiently, heater core may be blocked and need replacing , will need to be diagnosed by someone with the vehicle i.e a mechanic
