Hi,
It's odd that nothing works but dim interior lights. By chance, have you checked the battery itself? It may have internally shorted. If you have a voltmeter or multimeter, see if it is producing 12+ volts.
Next, there is a main fuse in the engine compartment fuse box. It's a 125-amp SBF fuse. If you look at pic 1 below, note that power from the battery goes there first and is distributed. Check that fuse (see pic 2). When checking, make sure the fuse is good and there is power to and from it.

Let me know what you find.
Take care,
Joe
