Locate the main electrical panel under the dashboard near the steering column for the quickest access to all circuit breakers. Each slot is marked with a small code indicating the component it safeguards, from lighting circuits to the ignition system.
Refer to the labeling inside the cover to identify slots responsible for interior accessories like the radio, heated seats, and power windows. Misidentifying a slot can result in unnecessary troubleshooting or blown fuses.
Use a continuity tester or multimeter to confirm that a particular circuit is live before replacing any protective element. This prevents accidental shorts and ensures that only the malfunctioning section is addressed.
Keep a record of replaced units and their amperage ratings. Many SUV models from this era rely on standardized sizes, but overloading or using the wrong rating can damage wiring or cause recurring faults.
Check auxiliary circuits in the engine bay for additional protective modules. Headlights, cooling fans, and power distribution to engine sensors often reside in separate boxes near the battery, each clearly marked for maintenance purposes.

Locate the power distribution center beneath the dashboard on the driver’s side for quick access to electrical circuits. Each labeled slot handles specific systems like headlights, HVAC, and the instrument panel.
Refer to the under-hood junction box to inspect high-current protectors connected to the ignition, cooling fans, and ABS module. Identifying amperage ratings printed on each holder prevents accidental overload.
Slots controlling auxiliary equipment such as the radio or rear defroster often require smaller inserts, typically 10A to 15A, which can be replaced individually without disturbing nearby connectors.
For lamps and turn signals, trace the connectors using the schematic printed inside the cover. This allows immediate identification of a weak link causing intermittent function or complete failure.
Electronic engine management relies on medium-capacity modules located in the main console cluster. A multimeter can confirm continuity before swapping units to avoid unnecessary replacements.
Check grounding points near the firewall; corrosion or loose screws can mimic blown components. Cleaning metal contacts restores proper current flow without removing any inserts.
Seasonal maintenance includes examining water intrusion near the box. Moisture can create corrosion or short circuits, making periodic drying and dielectric spray application highly recommended.
Label each slot after inspection to streamline future troubleshooting. Even a brief outage can be traced faster if amperage, system, and position are clearly noted on the inside cover or in a small notebook.
Identifying Fuse Locations in the 1999 Cherokee
Locate the power distribution panel under the dashboard on the driver’s side; it contains the majority of the miniature electrical protectors. Each slot is labeled with a number corresponding to the circuit it safeguards, from headlights to the interior lighting network.
The secondary compartment resides in the engine bay near the battery. This cluster handles high-current circuits like the ignition system, radiator fan, and horn. Use the molded legend inside the cover to match each slot to its specific circuit without trial and error.
Access Tips
- Remove the cover by pressing the release tabs; avoid forcing it to prevent cracking.
- Check the metallic strip in each holder for continuity; a broken segment signals a malfunctioning circuit protector.
- Keep a reference sheet of all numbers and corresponding components to simplify future inspections.
For intermittent electrical issues, start with connectors near the steering column and fuse blocks in the cabin. Inspect for corrosion, loose terminals, or discoloration, which often indicate overheating. Maintaining these locations regularly reduces unexpected system failures and prolongs the lifespan of wiring harnesses.
