Please note, that as we can get parts and accessories in quickly from a wealth of local suppliers, that we rarely keep or sell specific parts or accessories in stock.
Can you repair electrical issues in my motorhome?
Yes. CoolCar can diagnose and repair many electrical issues in motorhomes, caravans and RVs, particularly faults relating to appliances, fridges, batteries, charging systems, lighting, control panels, switches, wiring, plugs, sockets, and 12V power supply problems.
RV electrical faults can be frustrating because the issue is not always with the appliance itself. A fridge, heater, pump, light, or control panel may appear faulty, when the real problem is low battery voltage, poor connections, damaged wiring, a failed switch, voltage drop, or an issue with the charging system.
We can test the relevant parts of the system, identify where the fault is coming from, and explain the repair options before going ahead.
Where a job involves regulated mains electrical work or specialist certification, we will let you know and arrange or recommend the appropriate qualified tradesperson. This means you still benefit from our practical RV repair experience, while ensuring any regulated work is completed and signed off correctly.
We repair many RV electrical faults, and if the job requires specialist electrical certification, we’ll make sure the right qualified person is involved.
Do you provide any benefits to NZMCA Members?
Yes! CoolCar Air-Conditioning centres, North Shore, Hamilton and Henderson provide a 25% discount on labour for all caravan and motorhome repairs. Additionally, we also provide a 20% discount on labour on all repairs for those holding a Super Gold membership card. Please note, these two discounts cannot be applied together, rather its one or the other.
Just flash us confirmation of your SuperGold or NZMCA Membership and we'll apply the discount right away.
Do I need to bring the vehicle to your workshop, or can you come to me?
Unfortunately, our mobile service is reserved for heavy machinery, on-site equipment and trucks and tractors, planes, etc. Coming in and seeing us is the best way to receive the attention your motorhome needs, with the most amount of care.
Do you provide quotes before carrying out repairs?
Yes. Once we have inspected or diagnosed the vehicle, appliance, or system, we can provide a quote before carrying out repairs.
In most cases, we need to assess the issue first so we can identify the cause of the fault and understand what parts, labour, refrigerant, materials, or specialist testing may be required. This helps us provide a proper quote rather than guessing from symptoms alone.
We will explain what we have found, outline the recommended repair, and provide pricing before proceeding with the work. If anything changes during the repair, or if additional faults are found, we will contact you before carrying out any extra work.
What brands do you work with?
CoolCar is an authorised Dometic Service Dealer, which means we are approved to repair and replace Dometic products and assist with Dometic warranty claims.
We also work with a wide range of other leading motorhome and caravan brands, including Truma, Thetford, Thule, and many others.
Because motorhomes and caravans often use a mix of appliances, accessories, and specialist components, we’ll assess what you have, talk you through the available options, and help match the repair or replacement solution to your needs.
Whether you need an appliance repaired, a fridge replaced, a bike rack fitted, or a roof awning installed, we’ll do our best to recommend a practical option that suits your vehicle, budget, and how you use it.
Can you replace a faulty rooftop air-conditioning unit?
Yes. CoolCar can assess and replace faulty rooftop air-conditioning units on motorhomes and caravans.
Before recommending replacement, we will usually inspect the unit to confirm the fault and check whether repair is a practical option. Some issues may be caused by electrical faults, control problems, poor power supply, blocked airflow, fan faults, or damaged components rather than the whole unit needing replacement.
If replacement is the best option, we can talk you through suitable rooftop A/C options for your motorhome or caravan, including compatibility, size, cooling capacity, power requirements, and availability.
Once the right unit has been selected, we can remove the faulty unit and install the replacement. If any regulated electrical certification or final sign-off is required, we will arrange or recommend the appropriately qualified specialist to complete that part of the job.
Can you perform an EWOF or Gas Certification on my motorhome or caravan?
CoolCar does not issue Electrical Warrants of Fitness (EWOFs) or Gas Certificates ourselves, as these must be completed by appropriately qualified certifiers.
However, we can help with many of the repairs, checks, and preparation work that may be needed before your motorhome or caravan is certified. This includes pre-WOF and pre-EWOF checks, appliance fault-finding, fridge repairs, electrical diagnosis, lighting issues, battery and charging concerns, and general motorhome or caravan repair work.
Where your repair involves LPG fittings, gas connections, ventilation, compliance, or final gas sign-off, we can arrange or recommend a suitably qualified gasfitter to complete the certification side of the job.
This means you still benefit from CoolCar’s practical experience with motorhome and caravan appliances, fridges, electrical systems, accessories, and repairs, while ensuring any regulated electrical or gas certification is completed by the right qualified specialist.
In simple terms: we can help diagnose, repair, prepare, and carry out pre-WOF or pre-EWOF checks, but the final EWOF or gas certification must be issued by the appropriately qualified certifier.
