Used Mercedes-Benz EQA Fuse Box

Yes, the EQA does have fuse boxes — typically located in the engine compartment and inside the cabin — even though it is a fully electric vehicle with no internal combustion engine. Electric vehicles still use fuses and fuse boxes to protect the low-voltage electrical circuits covering lighting, comfort systems, and control modules. The high-voltage battery system has its own separate protection and is not part of the standard low-voltage fuse box you would be sourcing from a breaker.

The EQA (H243) launched in the UK in 2021 and has run as a single generation through to the current model, so a 2022 fuse box and a 2021 fuse box are from the same generation and are likely to be compatible. That said, Mercedes-Benz can introduce mid-cycle electrical revisions that affect fuse box configuration without a formal facelift, so confirm the part number against your registration with the breaker before buying.

Trim level — whether your EQA is Sport, Progressive, AMG Line, or AMG Line Premium — does not fundamentally change the fuse box specification, as fuse boxes are determined by the vehicle's electrical architecture rather than its trim grade. Some trim levels may add features such as heated seats or a panoramic roof that cause minor fuse box differences, so always cross-reference the part number against your exact registration with the breaker to make sure.

The drivetrain variant — EQA 250 (single motor, front-wheel drive) versus EQA 350 4MATIC (dual motor, four-wheel drive) — can affect the fuse box specification because each variant has different electrical consumers and control units. It is important to tell the breaker your exact model and registration rather than assuming any EQA fuse box will swap straight in.

The EQA (H243) and GLA (H247) share the same platform and many body components, so there is a possibility that some electrical parts overlap, but the EQA's fully electric architecture means its low-voltage fuse box configuration may differ from the combustion-engined GLA. This is a cross-model fitment question you should put directly to the breaker, quoting both registration numbers and asking them to compare part numbers before committing to a purchase.

Give the breaker your full registration number so they can verify the exact part number required for your vehicle's specification and build date, as fuse box configurations can vary with optional equipment and software generations. It is also worth asking the breaker which fuse box location the part is from — engine bay or interior — as the EQA has more than one, and you need to make sure you are replacing the correct unit.
