    I have a 2005 Volvo 780. My turn signal on the right side of my trailer is not working. I've been looking for a fuse or relay for it can't seem to find one. Can anyone help with locating it?

    That's the 1st place to check when you have trailer light problems on a Volvo. They will blow the fuses in the dashboard for the trailer lamps before the relays in the nose box of the trailer trip.
