It’s Just a Fuse—Until You Can’t Find It
You’ve diagnosed the fault. The test points to a blown fuse. Sounds simple, right?
But then comes the real challenge: finding the actual fuse.
Modern vehicles are full of surprises. Fuses tucked behind glove boxes. Modules hidden under seats. Secondary fuse panels you’d never expect. Suddenly, what should be a 5-minute fix turns into 45 minutes of stripping trim and searching Google Images.
For multi-brand workshops, this is a daily frustration—and it’s one that directly eats into your profit margin.
That’s where HaynesPro comes in. With precise, vehicle-specific component location diagrams, linked fuse box layouts, and wiring data, HaynesPro cuts fuse search time in half—or better.
Why Fuse Location is No Longer Straightforward
As vehicles have evolved, so have their electrical systems—and fuse locations along with them.
What used to be:
- One main fuse box under the bonnet
- One small panel in the dashboard
…is now more likely:
- Four or more separate fuse and relay boxes
- Vehicle-specific layouts that change even between trims
- Hidden or service-only access panels
EVs and hybrids take this even further, with high-voltage fuses, inverter protection circuits, and low-voltage sub-fuse blocks often concealed from easy view.
If your workshop relies on guesswork, online forums, or generic service data, you’ll waste valuable time chasing faults instead of fixing them.
How HaynesPro Solves the Fuse Hunt
HaynesPro makes fuse location fast, clear, and brand-accurate. Here’s how:
1. Instant Access to Fuse & Relay Locations
When you select a vehicle in HaynesPro, you get:
- A complete list of fuse and relay boxes
- Exact component locations—with diagrams that show where each panel is located inside the vehicle
This alone can save 20+ minutes on a job—especially for models with multiple hidden boxes (looking at you, Renault and BMW).
2. Zoomable, High-Resolution Diagrams
Diagrams aren’t just basic sketches. They’re:
- Colour-coded and zoomable
- Labelled clearly with fuse and relay functions
- Matched to the actual layout used in the vehicle’s production year and variant
No more guessing between pre-facelift and facelift layouts—or wondering if you’re looking at left-hand drive vs. right-hand drive.
3. Fuse-to-Component Linking
HaynesPro goes a step further: not only does it show you where the fuse is, it links fuses directly to components.
So if you’re dealing with a non-functioning blower motor or dead USB port, you can:
- Look up the component
- View the associated fuse
- See the fuse’s location, rating, and the box it belongs to
- Access related wiring diagrams or circuit test guides
It’s not just a map—it’s a fully integrated diagnostic system.
Real Workshop Example
A customer brings in a VW Golf VII with a non-working rear wiper. You’ve confirmed the motor is fine and you suspect a blown fuse.
Here’s what happens with and without HaynesPro:
Without HaynesPro:
You pull up a wiring diagram—if you can find one—and check three fuse boxes before identifying the right one. Then, you need to guess which fuse corresponds to the wiper system, because the labels aren’t clearly marked.
⏱ Time spent: 30–45 minutes
With HaynesPro:
You enter the vehicle, search “rear wiper,” and HaynesPro tells you the fuse location, amperage, associated wiring, and relevant diagrams—all on one screen.
⏱ Time spent: under 10 minutes
That’s not just time saved—it’s extra jobs you can complete in a day.

Built for Multi-Brand Efficiency
For independent workshops handling dozens of makes and models, this feature is essential. HaynesPro supports:
- European and Asian manufacturers
- LCVs and passenger cars
- EVs and hybrids
- Vehicles from the early 2000s to the latest plate
No more guessing where Vauxhall hid the headlight fuse. No more chasing down Peugeot’s under-seat box. Just quick, clear data—exactly where and when you need it.
Fuse Data is Just the Beginning
While fuse location is one of the most used features, it’s only a small part of what HaynesPro offers. You’ll also benefit from:
- Wiring diagrams and pin data
- Repair times and OEM procedures
- SmartFIX bulletins and known-fault guides
- ADAS calibration routines
- OEM service schedules
And because the platform is modular, you can choose the features you actually need.
