Check the interior power distribution layout near the driver’s side footwell to quickly identify which protective link corresponds to a malfunctioning component. This compact sedan from the mid-90s uses a clearly numbered array of blade-style protectors, each assigned to systems such as lighting, ignition control, audio unit, and climate functions. Referencing the labeled positions allows precise isolation of issues like non-working headlights or intermittent dashboard indicators.
Pay attention to amperage ratings stamped on each element, typically ranging from 5A to 30A. Installing a higher-rated insert can damage wiring, while a lower-rated one may fail under normal load. The layout typically groups related circuits–for example, exterior lighting elements are positioned adjacent to each other–making pattern recognition useful during diagnostics.
Use the cover legend or service manual illustration to match each numbered slot with its assigned circuit. If the cover is missing, a printed reference chart becomes necessary. Common placements include dedicated slots for fuel pump relay control, engine management unit supply, and accessory outlets. Accurate identification reduces guesswork and prevents unnecessary disassembly.
Inspect contacts for corrosion or heat damage when replacing any blown element. A discolored or melted housing indicates deeper electrical issues such as short circuits or excessive current draw. Cleaning terminals and ensuring tight seating improves reliability and prevents repeat failures in the same circuit path.

Locate the electrical panel under the dashboard on the driver’s side and use a labeled chart from the cover to match each circuit with its protective element; if the label is missing, assign positions manually by tracing wire colors (e.g., orange for constant power, pink for ignition-switched lines) and confirming with a multimeter set to continuity mode before replacing any blown component.
Layout and Circuit Mapping
The cabin-mounted unit contains grouped slots aligned in rows, typically separating lighting, engine control, and accessory circuits; headlights and tail lamps occupy higher-amperage positions (15–20A), while radio and interior lights use lower ratings (5–10A). The engine compartment panel mirrors this logic but handles starter relay, cooling fan, and fuel pump protection. Always match amperage precisely–installing a higher-rated element risks wire overheating. If no printed scheme is available, sketch your own by pulling one piece at a time and noting which system stops functioning, then restore it before moving to the next slot.
Diagnostics and Replacement Tips
Check suspected failures visually for a broken filament, but confirm electrically using a test light across both terminals; power on one side only indicates a break. Corrosion on contacts can mimic failure, so clean terminals with fine sandpaper before swapping parts. Repeated burnout signals a short circuit–inspect harness sections near sharp metal edges or heat sources like the exhaust manifold. Keep spare elements of multiple ratings in the glove compartment and label each position after verification to avoid repeated troubleshooting.
How to Locate and Identify Each Fuse in the 1994 Saturn SL2 Fuse Box
Open the driver-side door and inspect the side panel of the dashboard; remove the plastic cover to access the interior power distribution panel. A second unit sits under the hood near the battery, protected by a snap-on lid. Each cavity is labeled with small molded text or a printed insert on the cover–use this as the primary reference. Match the amperage rating stamped on the metal strip inside each blade component with the marking on the panel legend; typical ratings include 10A (red), 15A (blue), and 20A (yellow). Pull components straight out using a plastic puller or needle-nose pliers, checking for a broken internal strip or discoloration that indicates failure.
Follow a fixed sequence to avoid confusion and misplacement:
- Locate the legend on the cover; align its orientation with the panel layout before touching anything.
- Identify circuits by abbreviation (e.g., “IGN,” “ECM,” “DRL”); trace their positions row by row rather than jumping between sections.
- Verify amperage color and number before removal; replacing with a higher rating risks wiring damage.
- Inspect contact terminals for corrosion or looseness; clean lightly with electrical contact cleaner if needed.
- Reinstall each piece in the exact slot; double-check seating depth to ensure proper contact.
Under-hood components often control high-load systems such as cooling fans and ABS; these use larger cartridges or relays. Distinguish relays by their cube shape and pin layout; they are not interchangeable with blade-type elements. If a circuit remains inactive after replacement, test voltage at the terminals with a multimeter to confirm power supply and ground continuity.
