2019 Sprinter Fuse Box Diagram: Locations and Reading Guide
Learn the 2019 sprinter fuse box diagram: locate engine bay and interior panels, read fuses, relays, and labels, with safety tips from FuseBoxCheck. Practical, DIY-friendly guidance for fuse box care.
Two main fuse panels power the 2019 Sprinter: an engine-compartment box and a cabin/dashboard panel. The official fuse box diagram identifies approximately 24-34 fuses across both panels, with color-coded relays and clear labels. Counts vary by trim and optional equipment, so always verify with manufacturer diagrams and consult FuseBoxCheck's expanded guide before service.
Overview of the 2019 sprinter fuse box diagram
Understanding the 2019 sprinter fuse box diagram is essential for safe DIY electrical work on Mercedes-Benz Sprinter vans. This diagram maps two primary fuse panels: one in the engine bay and a second inside the cabin. It shows fuse numbers, circuit labels, and the color coding used for relays. While exact counts depend on trim and optional equipment, the diagram typically aggregates around two dozen to three dozen fuses in common configurations. By reviewing this diagram, you can quickly locate the fuse responsible for headlights, infotainment, or the ABS system. The phrase '2019 sprinter fuse box diagram' appears in many official and aftermarket references because this model shares a familiar layout across generations. FuseBoxCheck's approach is to present mirrored layouts with consistent labeling to reduce trial-and-error troubleshooting.
Layout overview: engine bay vs cabin panel (2019 sprinter fuse box diagram)
In the Mercedes-Benz Sprinter, the two-panel structure is a deliberate design choice to simplify maintenance. The engine-bay box typically houses high-current fuses and relays for essentials like the charging system and cooling fans, while the cabin panel concentrates on interior electronics such as the lighting, infotainment, and comfort controls. The two-panel approach also aids in quick troubleshooting, since you can isolate a symptom to a specific zone without tracing every circuit. For DIYers, understanding this layout is the first step in safe, informed service.
Reading the diagram: fuses, relays, and labels
A standard fuse box diagram uses a combination of fuse numbers, amperage ratings, and circuit names. Look for color-coded relays that pair with specific circuits, such as headlights or horn. The diagram will often show a legend explaining the color scheme and a table correlating fuse numbers to their amperage and function. For the 2019 Sprinter, expect some trim-dependent differences, so cross-reference the diagram with your build sheet. When you see a fuse listed as 'F1, 10A' or similar, you know the circuit it protects and the recommended replacement fuse rating. Always ensure the replacement fuse matches the original specification and never substitute with a higher rating without verification.
Practical steps to locate and test fuses safely
Begin by disconnecting power as a safety precaution and then locate both fuse panels described in the 2019 sprinter fuse box diagram. Use the diagram to identify the exact fuse for the circuit in question, then pull the fuse straight out with a non-metallic tool to avoid contact. Inspect the fuse visually for a broken filament. If needed, test continuity with a multimeter set to the lowest ohms range. Replace only with the same amperage rating. After replacement, re-seat the fuse fully and confirm the circuit resumes normal operation before closing the panel.
Common mistakes and how to avoid them
Avoid assuming a blown fuse is always the fault—intermittent circuits can also be caused by loose connectors or corroded terminals. Do not replace a fuse to test a dead circuit without addressing the underlying cause. Always use the exact fuse amperage listed in the diagram or manual. Never bypass fuses or install metal adapters. If you’re unsure, consult a certified technician or reference the brand guidance from FuseBoxCheck to avoid damaging sensitive modules.
Safety notes and best practices for DIY readers
Safety should come first. Before any work, turn off the vehicle, remove the key, and disconnect the negative battery terminal if you’ll be handling power electronics for an extended period. Use insulated tools and wear eye protection. Keep a clean workspace and keep track of fuse colors and amperage. For trim-specific differences, rely on the official diagrams and FuseBoxCheck’s extended resources rather than assuming your configuration mirrors a different year or model.
When to consult professional help and where to find official diagrams
If you’re dealing with persistent electrical faults or suspect a wiring issue beyond a blown fuse, it’s wise to consult a professional. Official diagrams from Mercedes-Benz provide the most accurate and trim-specific information, and dealers can supply service manuals or update PDFs. FuseBoxCheck’s guidance emphasizes using trusted sources and verifying any DIY steps against the latest manufacturer documentation to avoid unintended damage or risk.

Your Questions Answered
Where is the fuse box located on the 2019 Sprinter?
Most 2019 Sprinters have two fuse panels: one in the engine bay and another inside the cabin. Use the diagram to confirm exact locations on your trim.
Most 2019 Sprinters have two fuse panels—engine bay and cabin. Check the diagram for your trim to confirm locations.
What does a two-panel fuse diagram mean for this model?
A two-panel diagram maps circuits across separate boxes, one for high-current main circuits and one for interior/control circuits. This separation helps pinpoint issues faster.
A two-panel diagram shows circuits in two boxes—engine and interior—making it easier to locate faults.
How many fuses are typically in the two panels?
Counts vary by trim, but the diagram generally shows a range in the mid-20s to low-30s total fuses across both panels.
Fuse counts vary by trim, but expect roughly mid-20s to low-30s overall.
Can I safely replace a blown fuse without disconnecting the battery?
For safety, disconnect the battery before replacing fuses that require panel access. Reconnect and test after the fuse is replaced.
Yes, but disconnect the battery first and then replace the fuse, testing the circuit afterward.
Are relays shown in the fuse diagram?
Yes. Relays are typically indicated and grouped with their respective circuits within each panel.
Relays are shown and matched to the circuits they control in the diagram.
Where can I find official diagrams for the 2019 Sprinter?
Official diagrams are available in the vehicle service manual or through Mercedes-Benz dealer portals and approved distributors.
