Open the glove compartment and check the printed layout card to match each slot number with its amperage rating before removing any component.
The compact sedan uses a centralized electrical panel located behind the glove compartment, where low-current circuits such as interior lighting, infotainment, and control modules are arranged in tightly grouped rows. Each position is numbered and corresponds to a reference chart, allowing quick identification of the circuit tied to a specific slot.
High-load protection elements are placed separately within the engine compartment near the battery, where larger strip-style components manage systems like cooling fans, ABS, and power distribution. This separation reduces heat buildup and supports stable current flow for demanding equipment.
Amperage ratings range from 5A for sensitive electronics up to 60A for major systems, with color-coded housings that help confirm correct replacement. Always compare both the slot number and rating before installing a new component.
Accurate slot identification speeds up troubleshooting and prevents damage to wiring or modules. Use the layout card and numbering system together to trace faults without removing unnecessary components.
2007 BMW E90 Fuse Box Diagram with Layout and Circuit Details
Use the numbering chart inside the glove compartment panel to match each slot with its assigned circuit before removing any component.
The interior electrical panel is organized into tightly packed rows where low-amperage positions from 5A to 10A supply modules such as instrument cluster, air conditioning control, and lighting, while mid-range 15A–20A slots handle audio system, central locking, and power outlets. Higher demand circuits are routed through the engine compartment distribution unit, which contains strip-style high-current links and relays for systems like ABS and cooling fan. Follow these checks when identifying a circuit:
- Locate slot number stamped on the panel
- Confirm amperage by color and marking
- Cross-check with printed reference card
- Inspect for broken metal strip inside the component
Glove Box Fuse Panel Layout with Slot Numbers and Functions
Check the compartment behind the glove storage area first; remove the cover and locate the numbered grid printed on the panel surface to match each slot with its assigned circuit.
The internal module uses a structured numbering system, typically ranging from F1 to F60, depending on configuration. Lower positions often handle lighting and infotainment, while mid-range slots control climate modules and power outlets. Higher positions are usually linked to control units, airbags, and safety electronics. Always cross-check the amperage rating marked on each element before replacement.
Typical slot assignments include:
- F5–F10 for interior lighting and control switches
- F15–F25 for audio system, navigation, and display
- F30–F40 for HVAC system and blower motor
- F45–F55 for control modules and diagnostic interface
Use the plastic puller stored inside the panel area to remove components without damaging contacts. Incorrect rating installation may lead to wiring overheating, so always match the original specification printed on the panel legend.
If a circuit fails, inspect both the visible element and the corresponding relay nearby, as some functions depend on paired switching components rather than a single protective unit.
