For the horn, you can apply battery voltage to the Light Green/White wire terminals to test them. Alternatively you can use a test lamp or voltameter to check for power at the Light Green/white wire when horn buttons are depressed.
Have you check/tested the horn relay?
If the fog light fuse blows only when the light is turned on, then you need to check the bulbs and wiring for shorting. Our database does not have any wiring circuit for the foglights so it could possibly be after market.
If the door lights are not working, the chime would not work. Check/test driver door switch for proper operations.
