The 2015 Jeep Compass, like other vehicles, utilizes relay boxes to manage the electrical circuits for various components. Understanding the relay box diagram is crucial for diagnosing electrical issues and performing repairs. This guide will help you locate the relay box, understand its components, and troubleshoot potential problems.
Locating the Relay Box(es) in Your 2015 Jeep Compass
The 2015 Jeep Compass may have multiple relay boxes, depending on the trim level and optional features. Generally, you'll find them in these locations:
- Under the Hood: This is the most common location for a primary relay box. It's usually a plastic box containing multiple relays and fuses. Open your hood and look closely; it's often located near the battery or on the inner fender well.
- Passenger Compartment (Fuse Panel): Some relays and fuses might be located within the passenger compartment fuse panel, often found under the dashboard on the driver's side or passenger's side. Consult your owner's manual for the precise location.
Understanding the 2015 Jeep Compass Relay Box Diagram
Unfortunately, a single, universally accessible, online diagram specific to the 2015 Jeep Compass relay box isn't readily available. The layout and components can vary slightly depending on the vehicle's configuration. However, here's what you can expect to find:
Key Components within the Relay Box:
- Relays: These are electromechanical switches that control the flow of power to various circuits. Each relay typically controls a specific component or system (e.g., headlights, wipers, fuel pump).
- Fuses: These protect circuits from overloads. A blown fuse will interrupt power to the protected circuit. They're usually smaller and often have a clear plastic body showing a wire if blown.
- Wiring Harness: The wiring harness connects the relays and fuses to the vehicle's electrical system.
How to Interpret a Relay Box Diagram (If you have one):
If you can locate a diagram specific to your vehicle (often found in the owner's manual, or through a Jeep service manual), you'll see:
- Relay/Fuse Numbering: Each relay and fuse will have a number to easily identify it.
- Circuit Designation: The diagram will indicate what circuit each relay or fuse protects. This might be labeled with the component's name (e.g., "Headlights," "Power Windows").
- Wiring Connections: The diagram will show how the various relays, fuses, and the vehicle's wiring harness are interconnected.
Troubleshooting Electrical Problems in Your 2015 Jeep Compass
If you're experiencing an electrical issue, the relay box is a good place to start your troubleshooting.
1. Check the Fuses: Visually inspect the fuses for a blown wire (a broken filament inside). If a fuse is blown, replace it with a fuse of the same amperage rating. Never replace a fuse with one of a higher amperage; this can damage the electrical system.
2. Inspect the Relays: While less easy to visually inspect than fuses, check for any signs of physical damage or corrosion on the relay itself. You might need to remove the relay and carefully check the connections.
3. Test the Relays (Advanced): If you suspect a faulty relay, you can test it using a multimeter or a test light. Consult a repair manual or online resources for specific testing procedures. Caution: Working with vehicle electrical systems can be hazardous. If you're uncomfortable, consult a qualified mechanic.
4. Consult Your Owner's Manual: Your Jeep Compass owner's manual should contain a fuse and relay diagram specific to your vehicle's configuration. It's the best resource to start with.
5. Seek Professional Help: If you cannot identify the problem after carefully inspecting the fuses and relays, it is always best to consult a qualified mechanic or Jeep dealership for professional diagnosis and repair.
This guide provides a general overview. Remember that the specific layout and components of your 2015 Jeep Compass relay box may vary slightly. Always consult your owner's manual or a professional mechanic for accurate information and safe repair procedures.
