The above is highlighted fuses and R4 relay heater blower location that affect the Heater and Climate control
as well as Body Control Module which handles a lot of this from the Engine compartment side.
Being that this is a 2012, lots of those systems may have failed because their electronics have aged to a point where they've gone bad and will no longer work.
- F7 (Brown) 7.5A - Manual Climate Controls
- F10 (Blue) 15A - Radio
- F21 (Red) 10A - Body Control Module subsystem
- F4 (Green Square) - Main Buss Feed for Heater Blower Motor (Engine compartment side)
- R4 RELAY - Heater Blower Relay
Replace the fuse but it does not guarantee the part connected to it - will operate again.
Also, the Battery Positive terminal uses a red cover - pry it off and look for a set of plug-in harnesses that feed off the main Positive battery post - these may have blown - they are a type of cartridge fuse for high-amperage system feeds.
