The 1999 Jeep Cherokee, a rugged and reliable SUV, boasts a robust electrical system. Understanding your fuse box layout is crucial for quick troubleshooting and maintaining your vehicle's functionality. This guide provides a detailed overview of the fuse box locations and diagrams for your 1999 Jeep Cherokee, helping you locate and replace blown fuses efficiently.
Locating Your 1999 Jeep Cherokee Fuse Boxes
The 1999 Jeep Cherokee typically has two fuse boxes: one under the hood and another inside the passenger compartment. Knowing their exact locations is the first step in any electrical diagnosis.
Under-Hood Fuse Box (Power Distribution Center)
This large fuse box, often called the Power Distribution Center (PDC), houses high-current fuses and relays protecting major electrical components like the engine, lights, and cooling fans. It's usually located in the engine compartment, often near the battery. Consult your owner's manual for the precise location in your specific model. The manual will also contain a detailed diagram illustrating the fuse and relay positions.
Interior Fuse Box (Passenger Compartment)
This smaller fuse box is typically located inside the passenger compartment, often under the dashboard or in the center console. This box protects the interior electrical components, including power windows, lights, and accessories. Again, your owner's manual is your best resource for the exact location.
Understanding Your Fuse Box Diagrams
Once you've located the fuse boxes, understanding the diagrams is essential. The diagrams usually provide a legend detailing:
- Fuse Number: A numerical identifier for each fuse.
- Amperage Rating: The maximum current (in amps) the fuse can handle before blowing. Replacing a blown fuse with one of a lower amperage rating can lead to further damage.
- Circuit Description: A description of the electrical component protected by the fuse (e.g., headlights, power windows, radio).
Caution: Incorrectly replacing a fuse can cause damage to your vehicle's electrical system or even create a fire hazard. Always refer to your owner's manual for specific instructions and amperage ratings.
Troubleshooting Tips
If you suspect a blown fuse, follow these steps:
- Turn off the affected system. Before attempting any repairs, switch off the component that isn't working (e.g., headlights, radio).
- Locate the correct fuse. Use the diagram in your owner's manual to find the fuse associated with the malfunctioning component.
- Check the fuse visually. A blown fuse will usually show a broken filament visible through the clear plastic window.
- Replace the fuse. Only replace the blown fuse with a new one of the same amperage rating. Never use a higher amperage fuse as a replacement.
- Test the system. Turn the system back on to check if the problem is resolved.
If the fuse blows again immediately after replacement, there's likely a more significant underlying electrical problem that requires professional attention. Don't continue to replace the fuse; instead, consult a qualified mechanic.
Where to Find More Information
While this guide provides general information, the most accurate and up-to-date diagrams and information are found within your 1999 Jeep Cherokee owner's manual. This manual contains detailed schematics specific to your vehicle's year, make, and model. If you don't have a copy of your owner's manual, you may be able to find a digital version online through Jeep's website or reputable online automotive parts retailers.
This comprehensive guide equips you with the knowledge to confidently locate and interpret your 1999 Jeep Cherokee's fuse box layouts. Remember always to prioritize safety and consult your owner's manual for the most accurate and detailed information.
