Check the driver-side dashboard panel first, as it contains the main set of circuit protectors for lighting, audio, and climate controls. Remove the cover to view the slot numbering and match each position with its assigned system using the printed chart.
Look at amperage ratings on each component, typically ranging from 10A to 30A for cabin electronics. Always replace with the same rating to prevent overheating or repeated failure under normal load conditions.
For engine-related circuits, inspect the secondary panel located in the engine bay near the battery or firewall area. Disconnect the negative terminal before handling to avoid short circuits or damage to control units.
When diagnosing electrical faults, identify the affected system and trace it to its assigned slot. A broken metal strip inside the component indicates failure, while an intact strip suggests checking wiring, switches, or connectors instead.

Use the panel label under the dashboard to match each slot number with its assigned circuit before removing any component, ensuring accurate identification of systems like lighting, radio, and climate control.
Cabin circuits typically include 10A for dashboard illumination, 15A–20A for audio and accessory outlets, and up to 30A for power windows or seat mechanisms; inspect each unit individually and check the internal metal strip for visible breaks that indicate failure.
Engine bay distribution handles higher current loads such as ignition and cooling systems, often located near the battery; replace only with identical amperage ratings and recheck operation immediately after installation to confirm proper function.
Exact fuse panel locations in 1989 Nissan Maxima and how to access them
Check the driver-side dashboard edge first, visible when the door is open, where the main electrical panel is mounted behind a removable plastic cover.
Pull the cover straight outward to release the retaining clips. Use steady pressure rather than jerking movements to avoid breaking the mounting tabs.
The cabin panel contains most low-amperage circuit protectors linked to lighting, audio, and accessory systems, making it the primary inspection point for common electrical faults.
For engine-related circuits, locate the secondary distribution area under the hood near the battery or firewall.
Follow these steps to access it safely:
- Turn off ignition and remove the key
- Open the hood and secure it properly
- Find the protective cover near the battery
- Release clips or fasteners holding the lid
- Lift the cover without twisting
Avoid using metal tools when opening covers, as they can damage plastic parts or create accidental contact with electrical terminals.
After inspection or replacement, align all tabs and press covers back into place until fully seated to prevent vibration or loose fit during driving.
