Locate the primary junction panel behind the dashboard on the driver’s side, adjacent to the left kick panel. Identifying the correct access cover prevents unnecessary disassembly and reduces the risk of short circuits.
Label each circuit pathway clearly before attempting replacements. The small-scale schematic inside the lid shows amperage ratings and component associations, allowing precise tracking of ignition, lighting, and accessory lines.
Check relay positions carefully since misalignment can cause intermittent failures. A visual reference with numbered slots enables immediate comparison with operational circuits, minimizing diagnostic guesswork.
Use a digital multimeter to confirm continuity across all connectors. Measuring voltage drops under load highlights degraded contacts or overheating spots that are not obvious visually.
Document modifications with a simple chart noting fuse ratings and any aftermarket additions. Maintaining an updated record ensures future repairs remain straightforward and prevents inadvertent overloads.

Locate the main electrical panel under the hood on the driver’s side near the firewall. Each slot is numbered, with circuits for headlights, wipers, and ignition clearly indicated. Use a test light or multimeter to verify current flow before replacing any blown components.
Inside the cabin, the secondary control unit sits beneath the dashboard on the passenger side. Small rectangular modules manage accessory circuits like power windows, radio, and climate control. Labeling is stamped on the underside of the lid for quick identification.
Color-coded wiring simplifies tracing faults: red wires handle high-amperage devices, yellow for mid-range, and blue for low-draw systems. Cross-reference these with the numbered slots to prevent accidental short circuits and ensure proper reconnection.
For troubleshooting, remove one module at a time and inspect contacts for corrosion or burn marks. Cleaning with a dielectric spray restores conductivity and reduces the chance of repeated failures. Keep a spare set of micro-modules in the glove compartment for emergencies during long drives.
Locating the Electrical Panel in a 2002 Cadillac Seville SLS
Access the main control unit by opening the driver’s side interior panel near the lower dashboard. Slide the trim cover downward to reveal a rectangular casing with labeled switches and connectors. Check the owner’s manual for the exact side orientation, as it may differ slightly depending on left- or right-hand drive models. Keep a flashlight handy to see the numbered slots and colored tabs clearly.
Some auxiliary panels are tucked under the hood along the firewall.
- Look for a black plastic enclosure close to the battery terminal.
- Release the clips on the lid to inspect internal relays and circuits.
- Verify each slot marking to avoid confusion with ignition or lighting relays.
A compact layout means each segment serves multiple components, so labeling the lines before removing any element is recommended. Use gloves to prevent accidental contact with metal connectors while inspecting or swapping fuses.
