When it comes to electrical issues in your Ford E150 van, the first place you should check is the fuse box. The fuse box contains a variety of fuses and relays that protect your van’s electrical system from damage. In this article, we will discuss the Ford E150 van fuse box diagram, how it works, and some frequently asked questions to help you better understand and troubleshoot any electrical issues you may encounter.
What is a Fuse Box?
A fuse box is a collection of fuses and relays that are designed to protect your vehicle’s electrical systems from short circuits and overloads. When an electrical fault occurs, the affected fuse will break the circuit and prevent further damage to the system. The Ford E150 van fuse box diagram is a schematic representation of the fuse box layout, showing which fuses and relays are responsible for which electrical systems.
The Ford E150 van fuse box diagram is usually located under the dashboard on the driver’s side, near the steering column. It is also possible that the fuse box diagram is located in the owner’s manual or on the back of the fuse box cover.
Ford E150 Van Fuse Box Diagram
The Ford E150 van fuse box diagram is divided into three sections: Fuse Panel, Power Distribution Box, and Auxiliary Relay Box. Each section contains a list of fuses and relays, their function, and their location within the fuse box. Here is a breakdown of each section:
Fuse Panel
| Fuse/Relay | Location | Function |
|---|---|---|
| 1 | 10A | Trailer Tow Connector |
| 2 | 10A | Electronically Controlled Air Suspension (ECAS) |
| 3 | 20A | Power Point |
| 4 | 20A | Trailer Tow Connector |
| 5 | 20A | Powertrain Control Module (PCM) Relay |
| 6 | 20A | Run/Accessory – Wipers, Instrument cluster, Audio for XL/STX |
The Fuse Panel section contains fuses and relays that control various systems such as the trailer tow connector, power point and powertrain control module.
Power Distribution Box
| Fuse/Relay | Location | Function |
|---|---|---|
| 1 | 60A | Battery Junction Box (BJB) |
| 2 | 30A | PCM Power Relay |
| 3 | 30A | Main Light Switch |
| 4 | 20A | Powertrain Control Module (PCM) System Relay |
| 5 | 30A | Windshield Wiper Motor |
| 6 | 30A | Trailer Tow Connector |
The Power Distribution Box section contains fuses and relays that control systems such as the battery junction box, main light switch, and windshield wiper motor.
Auxiliary Relay Box
| Fuse/Relay | Location | Function |
|---|---|---|
| 1 | -20A | Not Used |
| 2 | 30A | Transmission Control Switch (TCS) |
| 3 | -Not Used- | -Not Used- |
| 4 | -Not Used- | -Not Used- |
| 5 | -Not Used- | -Not Used- |
| 6 | 20A | Trailer Tow Running Lamp Relay |
The Auxiliary Relay Box section contains fuses and relays that control the transmission control switch and the trailer tow running lamp relay.
Ford E150 Van Fuse Box Diagram: Frequently Asked Questions
1. What is a fuse?
A fuse is an electrical safety device that is designed to protect electrical systems from damage caused by excess current. When a circuit is overloaded, the fuse will break the circuit and prevent further damage to the system.
2. How do I know if a fuse is blown?
There are a few ways to tell if a fuse is blown. One way is to visually inspect the fuse. If the metal inside the fuse is broken or the fuse appears discolored, it is likely blown. Another way is to use a multimeter to check the continuity of the fuse. If there is no continuity, the fuse is blown.
3. What should I do if a fuse is blown?
If a fuse is blown, it will need to be replaced. You can do this by locating the corresponding fuse in the Ford E150 van fuse box diagram, removing the blown fuse, and replacing it with a new one of the same amperage rating.
4. Can I use a fuse with a higher amperage rating?
No, you should never use a fuse with a higher amperage rating than what is specified in the Ford E150 van fuse box diagram. Doing so can cause damage to the electrical system and create a safety hazard.
5. What if I replace a blown fuse and it immediately blows again?
If you replace a blown fuse and it immediately blows again, it may indicate a more serious electrical issue. It is recommended that you take your Ford E150 van to a qualified mechanic for further diagnosis and repair.
Conclusion
The Ford E150 van fuse box diagram is an essential tool for troubleshooting electrical issues in your van. By understanding the function of each fuse and relay, you can quickly and easily identify and repair any electrical problems that may arise. Remember to always use fuses with the proper amperage rating and seek professional help if you encounter any serious electrical issues with your Ford E150 van.
