2017 Focus Fuse Box Diagram: Exploring the Fuse Boxes

2017 Focus Fuse Box Diagram: Find the right fuse for the circuit you’re working on

In your 2017 Focus, you’ve got three fuse boxes to keep track of: the Engine Compartment Fuse Box, which is also called the Power Distribution Box under the hood, the Body Control Module (BCM)/Passenger Compartment Fuse Box, and the luggage compartment fuse box.

Let’s start with the one under the hood. Just pop the hood and look for the power distribution box on the driver’s side near the firewall. It’s like the nerve center for your truck’s major systems—things like engine management, emissions, and ABS brakes are all controlled by the fuses in this box.

Now, for the second fuse box, crawl under the dash on the passenger side. It’s tucked away behind a cover directly under the glove box. The trim pulls away, and You’ll see two tabs sticking out. All You need to do is pinch the tabs on either side and pull down to release the fasteners. This one takes care of all the interior electrical stuff like the radio, power windows/locks, climate controls, and those handy courtesy lights. It’s essential to give both of these fuse boxes a once-over every so often to make sure none of the fuses are blown. If your electrical gadgets aren’t acting right, it might be a sign that something’s amiss with the fuses.

The luggage compartment fuse box is located in the cargo area next to the spare tire.

A note about fuses, battery power and keep alive memory

If you disconnect the battery or remove the PCM fuses from the fuse box, the PCM will lose its adaptive memory and baseline throttle body position. You can avoid this by providing backup power using a jumper pack and an inexpensive OBDII cable. See this article for more information on providing backup power to prevent the loss of adaptive memory. Or, you can perform a throttle body relearn procedure and then drive the vehicle so it can relearn the new adaptive memory settings. See this article for instructions on how to perform a 2017 Focus throttle body relearn procedure.

Tips to diagnose electrical issues on your 2006 Explorer

If your power windows don’t work
• Ford uses two methods to run the power windows. In late model vehicles each door is equipped with a door module. The module receives inputs from the window switch and mirror switch and then provides power to the window motor or power mirror.

In other models, the power is provided by the body control module. windows.

If your blower motor doesn’t work
The blower motor gets its power from the blower motor Fuse #10 40A in the power distribution box.
If the circuit you’re working on contains a relay
• A simple way to test a relay is to swap in a similarly shaped relay and see if the component works.
• If that doesn’t work, remove the relay and test for power to the relay control coil and contacts using a multimeter. For more information on relay testing, see this article.
