Where is the power mirror relay on a 1998 Lincoln navigator?

The power mirror relay on a 1998 Lincoln Navigator is typically located in the fuse box, which is found under the dashboard on the driver's side. You may need to consult the vehicle's owner manual for the specific location of the relay within the fuse box. It's important to check both the under-dash fuse box and any additional fuse panels, as some components may be housed in different areas. If you're having trouble locating it, a wiring diagram or service manual can provide more detailed information.
