2014 Ram 1500 Fuse Box Diagram

As an ASE-certified master technician, I've seen my fair share of electrical gremlins. Before you start tearing apart wiring harnesses, the first and most important step is to check the fuse box. This guide will serve as your reference page for the 2014 Ram 1500, helping you quickly locate and identify the fuses and relays in your truck.

Quick Answer: 2014 Ram 1500 Fuse Box Locations

Your 2014 Ram 1500 has two primary fuse box locations:

• Under-Hood Fuse Box (Power Distribution Center): Located on the driver's side of the engine bay, near the battery.
• Interior Fuse Box: Located under the driver's side dashboard, to the left of the steering column.

Under-Hood Fuse Box (Power Distribution Center) Diagram

The Power Distribution Center (PDC) is the main fuse box for your Ram 1500. It houses high-amperage fuses and relays that control critical engine and body functions. To access it, open the hood and look for a black box on the driver's side. Press the tabs on the cover to remove it. Inside the cover, you will find a diagram that should match the one below, but always trust the diagram on your specific vehicle.

Below is a list of the most common fuses and relays you'll find in this box.

Relay Locations: The PDC also contains critical relays for functions like the Fuel Pump, Starter, A/C Clutch, and Blower Motor. They are typically black or gray square boxes and their positions are marked on the fuse box diagram.

Interior Fuse Box Diagram

The interior fuse box manages most of the cabin electronics, including your radio, power outlets, and instrument cluster. It's located under the dashboard on the driver's side. You may need to remove a small trim panel to access it.

Important Note: Fuse numbers in this panel can vary significantly based on your truck's trim level and options (Tradesman, SLT, Laramie, etc.). The list below covers the most common circuits, but always verify with the fuse legend printed on your truck's fuse box cover or owner's manual.

How to Test a Fuse

A blown fuse is a common and easy-to-fix issue. Here’s how to check if a fuse is your problem:

1. Safety First: Turn the ignition off and remove the key.
2. Locate and Remove: Using the diagrams above, locate the suspect fuse. Use the fuse puller tool (often found in the fuse box itself) to gently pull the fuse straight out.
3. Visual Inspection: Hold the fuse up to the light. Inside the plastic body, you will see a thin metal strip. If that strip is broken or looks burnt, the fuse is blown and needs to be replaced.
4. Confirm with a Multimeter: The most reliable method is to use a multimeter set to the continuity setting (it looks like a sound wave symbol). Touch the probes to each of the two metal tabs on the top of the fuse. If the multimeter beeps, the fuse is good. If it stays silent, the fuse is blown.

When replacing a fuse, always use a new fuse with the exact same amperage rating. Using a higher-rated fuse can cause severe damage to the circuit and create a fire hazard.

Common Blown Fuses on the 2014 Ram 1500

Over the years, we see certain patterns of failure. On this particular Ram model, these are the fuses that tend to blow most often:

• Cigar Lighter / 12V Power Outlet (Fuse F60 or F62): This is by far the most common issue. It's almost always caused by a faulty phone charger, a loose coin falling into the socket, or a malfunctioning accessory that was plugged in. Before replacing the fuse, unplug everything and inspect the socket for foreign objects.

• Fuel Pump Fuse (Fuse F20): If your truck cranks but won't start, the fuel pump fuse is a prime suspect. While a fuse can blow from age, it can also be a sign that the fuel pump itself is failing and drawing too much current. If a new fuse blows immediately or soon after, it's time to have your fuel pump diagnosed.

• Trailer Tow Fuses (F03, F21): If your trailer lights or electric brakes aren't working, check these fuses. However, the root cause is often on the trailer side. A bad ground, frayed wire, or short in the trailer's wiring harness will repeatedly blow the fuses in your truck. Always inspect the trailer connector and wiring first.

Electrical diagnostics can be tricky. If you've checked the fuses and your problem persists, it may be time to consult a professional. Find a trusted shop on Repairius.
