To find it, you'll likely need to:
* Locate the fuse box: This is usually under the dashboard on the driver's side. The fuse box cover should have a diagram showing the fuse locations.
* Look for the flasher relay: It's a small, square or rectangular unit, often with a socket that allows you to easily remove it. It might be labeled "hazard flasher" or have a similar indication.
* Check nearby areas: If it's not directly in the fuse box area, it might be tucked away in a nearby space within the dashboard.
If you can't find it by visual inspection, consulting a 1998 Ford Mondeo repair manual or an online parts diagram specific to your vehicle's year and model would be helpful. These diagrams often pinpoint the exact location of components.
