Fuses and Relays

These are located in two sites on the Mondeo. Its easy to guess which one you'll need to open. If its raining it will be the engine compartment box and if its 90 degrees it will be the passenger foot well box

See also the fuse blowing problem page if the engine is not running

The Engine compartment Box (AUXILIARY)


This box is easy to find. It is on the passenger side of the engine compartment at the front next to the Battery. Helpfully the lid inside is marked with all the fuses and relay information

The Passenger Foot well Box (MAIN)

This box is a bit more awkward it is on the bulkhead behind the glove compartment and is accessed by reaching up into the passenger foot well. I tend to lay on my back on the passenger floor with my legs and feet outside the car. You will need a torch.
