Where is the relay for the 4 way flashers on a 1999 western star?

In a 1999 Western Star, the relay for the 4-way flashers is typically located in the fuse panel, which is usually found under the dashboard on the driver's side or in the engine compartment. You can identify the specific relay by consulting the vehicle's owner's manual or the fuse box diagram, as it will indicate the exact position and label for the 4-way flasher relay. If you're having trouble locating it, checking for a loose connection or a blown fuse might also be helpful.
