Vehicle system uses 2 power supply sources, one when the ignition is OFF and another is when the ignition switch is turned ON. If the power source is missing from the circuit when ignition switch is OFF, you would not be able to operate them until you turn on the ignition switch.
With so many items not working, it definitely is a power supply fault and when checking fuses, they might look good so a test lamp or volt meter would be the best way to go about checking.
No relays are used for power suppy of these circuits.
Check the following fuses for battery voltage: Fuses might be good, but I need to know if battery voltage are available at these points to understand the location where the power supply is missing.
Fuse # 1 ( 15 A )
Fuse # 10 ( 30 A )
Fuse # 17 ( 10 A )
Fuse # 11 ( 20 A )
All above in underdash fuse box.
Fuse A ( 50 A ) in under hood ( engine compartment ) fuse box.
