Locate the interior electrical panel on the driver side kick area and remove the trim cover to access the relay and circuit grid. Use a small flashlight to read the labels printed near each slot, and match them with the assigned amperage values stamped on each protective link.
Check the rating before removal by noting the color and number marking on each component, such as 10A, 15A, or 20A. Pull the piece straight out using plastic tweezers to avoid damaging контакты, and inspect the metal strip inside; a broken or burnt strip indicates a failed circuit.
Refer to the slot numbering sequence molded into the panel housing to identify systems like lighting, audio, climate control, and ignition circuits. This numbering aligns with factory wiring references, allowing accurate tracing of faults without removing additional interior panels.
After replacement, reinstall the panel cover securely and test the affected system immediately. If failure repeats, inspect wiring harnesses and connected components rather than replacing the same protective link again.
1995 Lexus LS400 Under Dash Fuse Box Diagram and Fuse Identification
Open the driver side lower trim panel and locate the interior power distribution panel positioned near the steering column; align each slot with the molded numbering grid to match circuits accurately.
Identify each protective element by amperage and function using the factory labeling pattern, which typically includes short abbreviations for systems. Common assignments include:
- IGN – ignition circuit
- ACC – accessory power
- TAIL – rear lighting
- RADIO – audio system
- ECU – engine control unit supply
Check amperage ratings before removal; most slots use 10A, 15A, and 20A units distinguished by color coding. Installing a higher-rated piece risks wiring damage and component failure.
Use a plastic puller tool to extract each element vertically, avoiding metal tools that can cause short circuits. Inspect the internal metal strip for breaks or burn marks to confirm failure.
Follow the slot numbering sequence stamped into the panel frame to trace circuits:
- Locate the number next to the slot
- Match it with the circuit list printed on the cover or service manual
- Verify the connected system by testing operation after removal
Reinstall components firmly into their original positions and secure the panel cover; test systems such as lighting, climate control, and audio immediately to confirm correct identification and replacement.
Exact Location of the Under Dash Fuse Box in 1995 Lexus LS400
Remove the lower driver side trim panel near the steering column to access the interior power distribution unit mounted against the side wall; it sits slightly above the footwell area and is partially covered by a plastic защитная крышка.
The panel is positioned to the left of the steering wheel, close to the kick panel, and aligned vertically. Look for a rectangular housing with multiple colored blade-type elements arranged in rows. Access may require loosening one or two clips or screws securing the trim. Use a flashlight to clearly see the slot markings and avoid misidentifying adjacent relay units.
Access Tips for Tight Interior Space
Slide the driver seat fully backward and lower your head near the педальный узел for a direct view. Work with one hand while stabilizing yourself to prevent strain on wiring. Avoid pulling surrounding harnesses; only interact with the mounted panel and its removable cover.
