Park lights won't turn off by the switch or when you pull the fuse.

This means someone has wired power to the parking light circuit, here is the parking light wiring diagrams so you can see how the system works which is pretty basic, there are no relays that can stick on causing the issue. Here is a guide to help you check the wiring:
