Locating the correct relay box diagram for your 2014 Jeep Compass is essential for electrical troubleshooting and repair. Here are the most effective methods and reliable resource types:
1. Identifying the Correct Relay Box
Understand that the 2014 Compass typically has three primary Power Distribution Centers (PDCs):
- Underhood Fuse/Relay Box (IPDC): Main box near the battery, housing larger fuses and major relays (e.g., ignition, starter, fuel pump).
- Integrated Power Module (IPM): Often located under the hood near the brake fluid reservoir or inside the cabin (check driver's side footwell kick panel), primarily handling interior and convenience systems.
- JBJB (Junction Block/Junction Box): Usually inside the cabin, frequently near the driver's knee bolster or passenger side footwell, managing interior lighting, audio, etc.
Carefully note the physical location and any markings (IPDC, IPM, JB) on the cover you need the diagram for.
2. Accessing Official Jeep Documentation
The most accurate diagrams come directly from FCA (Fiat Chrysler Automobiles):
- Official Service Manuals: Reputable online platforms specializing in OEM automotive manuals offer digital copies containing the complete electrical section. Search using keywords like "2014 Jeep Compass Service Manual". Verify seller/platform credibility.
- Manufacturer Parts Portals: Official parts departments sometimes provide schematics with parts listings. Search by VIN on manufacturer-authorized parts sites.
3. Utilizing Automotive Repair Platforms
Several established platforms aggregate repair data:
- Subscription-Based Repair Databases: Leading platforms used by professional technicians contain comprehensive wiring diagrams and fuse/relay layouts. While requiring payment, they offer the highest reliability.
- Dedicated Vehicle Forums: Major Jeep or Compass enthusiast forums often have dedicated technical sections. Search extensively within these forums using terms like "2014 Compass relay diagram" or "PDC layout". Members frequently share verified information.
4. Deciphering Existing Box Covers & Labels
Physically inspect your relay boxes:
- Cover Diagram: The plastic cover on the IPDC or IPM often has an embossed or printed diagram listing fuse/relay amperages and functions. Clean the cover thoroughly to read it.
- Component Labels: Relays and fuses themselves may have markings identifying their standard function (e.g., "FOG LP" for Fog Lamp). Cross-reference this with the positions.
5. Safety Tips & Best Practices
- Verify Information: Always double-check diagrams against your physical components before testing or replacing parts. Location and function can vary slightly by trim/package.
- Disconnect Battery: Before inspecting or replacing any fuse or relay, disconnect the negative battery terminal to prevent shorts.
- Beware Unverified Sources: Free image search results or obscure websites often provide incorrect or model-year-specific information that doesn't match your 2014 Compass. Prioritize official sources and reputable paid databases or active, well-moderated forums.
By systematically checking physical box covers, consulting official service manuals or professional repair databases, and leveraging insights from established enthusiast communities, you can locate the precise relay box diagram needed for your 2014 Jeep Compass.
