My 05 Escape was making a very loud buzzing noise, until I found which relay it was and removed it.

I replaced it and it still makes the noise so the relay isn't the issue but what it controls but I can't find that out. Manual did not help cause the diagrams are only for under the hood or the passenger panel, this relay came from the other side of the passenger fuze panel (had to remove change tray to get at it).

Any help would be much appreciated.
