I don’t know why the video won’t load.

 

yes.
And check the outside connection from the battery, check the connections to the battery, check the maxi fuse near the battery, make sure all of the fuses and relays in both fuse boxes are firmly seated.
Check if the ignition switch recall has been done, link in my sig.

 

You could try tightening the 3 or 4 bolts inside the fuse block before you go to the trouble of taking it apart. They need to be tightened more than you think.

 

Don't attempt to diagnose an electrical problem with an iffy battery. Sometimes, the battery is the entire problem. You can get it load tested at most chain parts stores. Then, charge it and let it sit at least overnight and make sure it's holding 12.6V minimum.

If you buy a new battery, at least you'll have something to show for it. Non-returnable electrical parts you didn't really need, not so much.
