If something in your campervan or motorhome has stopped working, is behaving unpredictably or was never installed correctly, WeConvert can help identify the problem and recommend the right repair.
From our private workshop in Blackburn, we provide campervan and motorhome fault finding and repair services for customers across Blackburn, Lancashire and the surrounding North West.
We work on professionally converted vans, factory-built campervans, motorhomes and self-build conversions. Whether you are dealing with an electrical problem, a charging fault, a leaking water system or a damaged interior fitting, we take a methodical approach to finding the cause rather than replacing parts unnecessarily.
Campervan and Motorhome Fault Finding
Some faults are immediately visible. Others only appear when the van is connected to mains power, running from the leisure battery, exposed to rain or used off-grid.
A leisure battery that keeps going flat, for example, could be caused by the battery itself, an unsuitable charging setup, a failed charger, poor cable connections or an unexpected drain elsewhere in the system.
Our first priority is to establish what is actually causing the problem.
Where the cause is not obvious, we begin with a chargeable diagnostic appointment. This allows us to inspect the installation, carry out appropriate testing and determine the most sensible next step.
If the problem can be resolved during the initial appointment, we will discuss this with you. Where additional parts or more extensive work are required, we will explain our findings and provide a quote before proceeding.
Campervan & Motorhome Electrical Repairs
Electrical faults can be frustrating, intermittent and difficult to trace without testing the complete system.
We can investigate problems involving:
- Leisure batteries that are not charging correctly
- Batteries that lose charge unusually quickly
- Split-charge relays and DC-to-DC charging systems
- Solar panels and solar charge controllers
- Battery chargers and mains hook-up supplies
- Inverters and 230V equipment supplies
- 12V lighting, sockets and USB outlets
- Blown fuses and repeatedly tripping protection devices
- Loose, damaged or poorly terminated wiring
- Control panels and battery-monitoring displays
- Electrical systems installed during previous conversions
- Unexplained power loss to pumps, fridges, heaters or other equipment
Where a larger upgrade is a better solution than repeatedly repairing an unsuitable system, we can also discuss our campervan and motorhome electrical and solar services.
We do not provide engine-management diagnostics, starter-motor repairs or general base-vehicle auto-electrical work. Our work is focused on the habitation and conversion systems inside the campervan or motorhome.
Leisure Battery and Charging Problems
Charging faults are among the most common problems found in converted vans.
You may need an assessment if:
- The leisure battery is flat after a short period of use
- The battery does not charge while driving
- Solar charging has stopped working
- The battery monitor gives inconsistent readings
- The system works on hook-up but not off-grid
- The system works while driving but not from solar
- A new lithium battery is not performing as expected
- Cables, terminals or charging equipment become unusually warm
- Electrical equipment cuts out when a larger load is switched on
We assess the system as a whole, including the battery type, charger settings, cable sizes, connections, fusing and expected power usage.
This helps avoid replacing a battery when the real problem lies elsewhere in the charging system.
Diesel Heater Faults
A diesel heater that will not start does not always need replacing.
Common causes can include:
- Low battery voltage
- Poor electrical connections
- Air in the fuel line
- An unsuitable fuel supply
- Blocked or incorrectly routed pipework
- Controller or wiring faults
- Installation problems
- Error codes caused by repeated failed starts
We can inspect the installation and identify whether the problem is related to the heater, its electrical supply, fuel delivery or the way it has been installed.
Where a replacement or complete new system is required, learn more about our campervan and motorhome diesel heater installation service.
Some manufacturer-specific internal heater repairs may require referral to an approved service provider. We will explain this clearly where applicable.
Water System and Plumbing Repairs
Small water-system problems can quickly cause damage to flooring, furniture and insulation if they are ignored.
We can investigate and repair issues involving:
- Water pumps that will not run
- Pumps that continue running after the tap is closed
- Poor or inconsistent water pressure
- Leaking taps, sinks and pipe connections
- Split or damaged water pipework
- Fresh-water and waste-water tanks
- Tank fittings, fillers and drain valves
- Underslung pipework and connections
- Loose or damaged plumbing components
- Water systems that have not been winterised correctly
- Existing installations that need altering or improving
Where you need a larger installation rather than a repair, visit our campervan and motorhome water systems page.
Window, Rooflight and Water-Ingress Repairs
Water entering around a window or rooflight should be investigated promptly. The visible drip is not always directly beneath the point where water is entering.
We can inspect problems involving:
- Leaking campervan windows
- Leaking rooflights and roof fans
- Failed sealant or seals
- Loose window frames
- Poorly fitted aftermarket windows
- Damaged trims and internal finishing
- Water marks around apertures
- Condensation being mistaken for a leak
- Previous repairs that have not solved the problem
Once the likely entry point has been identified, we can advise whether the fitting can be resealed or whether removal and refitting is the better long-term option.
We also offer campervan window, rooflight and ventilation installation for new installations and replacements.
Extensive damp or structural damage within a coachbuilt motorhome body may require a specialist body-repair workshop. We will be honest where a job falls outside our scope.
Interior and Furniture Repairs
Constant movement, vibration and regular use can eventually loosen or damage furniture and fittings inside a campervan or motorhome.
Our interior repair work can include:
- Loose cupboard doors and hinges
- Damaged catches and latches
- Drawers that no longer operate properly
- Loose panels and trims
- Damaged worktops
- Storage alterations
- Bed-frame repairs and modifications
- Replacement furniture panels
- Rattles caused by poorly secured fittings
- Improvements to an impractical existing layout
- Corrections to incomplete or poorly finished conversion work
For larger alterations, see our campervan and motorhome interior modification service.
We also design and supply campervan furniture kits for customers planning a larger interior replacement or self-build project.
Repairs to Self-Build and Previously Converted Vans
You do not need to have bought or converted your van through WeConvert.
We can assess:
- DIY campervan conversions
- Conversions completed by another company
- Older conversions requiring modernisation
- Vans purchased with unknown installation history
- Part-finished conversion projects
- Work that has failed an inspection
- Installations where the original converter is no longer available
- Campervans that need correcting before sale or future use
Before accepting a repair, we may need to inspect how the existing system has been built. Previous work sometimes needs to be made accessible before it can be tested or altered safely.
Where the van requires several stages of work rather than an isolated repair, our partial campervan conversion service may be a more appropriate option.
Motorhome Habitation Repairs
We can also undertake selected repairs and upgrades to the living area systems of coachbuilt and panel van motorhomes. Common enquiries include leisure batteries that are not charging, failed solar systems, water pumps that continue running, leaking pipework, faulty lighting, diesel-heater problems, damaged rooflights and interior fittings.
Our work is focused on the habitation systems rather than the engine, chassis or mechanical servicing. Extensive structural damp damage or manufacturer-specific appliance repairs may need to be referred to an appropriate specialist.
Our Repair Process
1. Tell us what is happening
Send us details of the vehicle, the symptoms you have noticed and when the fault occurs.
Photographs of the equipment, control panels, wiring, error messages or visible damage are useful, but they will not always be enough to diagnose the problem remotely.
2. Workshop assessment
We arrange an appointment at our Darwen workshop and inspect the relevant system.
Where fault finding is required, we will explain the diagnostic charge before the booking is confirmed.
3. Diagnosis
We test the likely causes and assess the condition of the existing installation.
Our aim is to identify the underlying fault rather than replace parts based on guesswork.
4. Findings and quotation
If further work or replacement parts are required, we explain what we have found and provide a quote or cost estimate.
No significant additional work is undertaken without your approval.
5. Repair and testing
Once authorised, we complete the agreed repair and test the affected system before the van is returned.
Where we identify unrelated concerns, we will bring them to your attention without automatically adding them to the job.
What We Do Not Repair
We specialise in the conversion and living-area systems within campervans and motorhomes.
We do not currently provide:
- Engine or gearbox repairs
- Mechanical servicing
- Brake, steering or suspension repairs
- MOT testing or MOT preparation
- General base-vehicle diagnostics
- Accident bodywork
- Large-scale coachbuilt body reconstruction
- Emergency roadside assistance
For mechanical or chassis-related problems, you will need a suitable garage or commercial vehicle specialist.
Gas-related faults must be identified when making your enquiry. LPG work is only undertaken where it falls within the agreed scope and can be completed, tested and signed off appropriately. Where specialist inspection or certification is required, we will explain this before accepting the work.

Frequently Asked Questions
Do you repair motorhomes as well as campervans?
Yes. We can undertake selected habitation-area repairs and upgrades on campervans and motorhomes.
We do not provide engine, chassis or mechanical motorhome servicing.
Do you work on vans converted by someone else?
Yes. We can inspect professionally converted vans, suitable self-builds and conversions completed by another workshop.
We may need to assess the existing installation before confirming what repair work is possible.
Can you tell me the repair cost from photographs?
Photographs help us understand the issue, but fault-finding work usually cannot be quoted accurately until the system has been inspected and tested.
We will explain any initial diagnostic charge before booking.
Can you repair a leisure battery that keeps going flat?
We can investigate why the battery is losing charge or failing to recharge.
The cause may be the battery, charger, solar system, DC-to-DC charger, wiring or an electrical drain elsewhere in the van.
Can you repair an unfinished DIY conversion?
Yes, subject to an initial inspection.
Depending on the amount of work required, this may be treated as a repair, an interior modification or a partial campervan conversion.
Can you repair gas appliances?
Gas-related work is assessed separately and must be mentioned when enquiring.
Where a repair requires specialist appliance servicing, LPG certification or work beyond our agreed scope, we may recommend an appropriate specialist.
Do you provide a mobile repair service?
Our main repair service is workshop-based and visits are by appointment.
This gives us proper access to tools, testing equipment and workshop facilities.
How quickly can you inspect my van?
Availability depends on the current workshop schedule and the nature of the fault.
Send us the vehicle details, symptoms and photographs, and we will advise on the next suitable appointment.
