Nissan Leaf air-con problem

Air conditioning is an essential feature of your Nissan Leaf. It keeps you warm in the winter and cool in the summer while ensuring your windows remain clear, enhancing safety.

But what happens if it starts malfunctioning?

A recent client brought their Nissan Leaf to our experts at Fitch Autos because the air conditioning wasn’t working. In addition to this issue, the heating would take an unexpectedly long time to warm up, which is far from ideal. 

As the air con wasn’t performing as it should, which could’ve ended in visibility issues. This is the last thing you’d want from your Nissan. 

Fortunately, our team at Fitch Autos has extensive experience with Nissan vehicles and can solve any air conditioning fault during the first visit.

What we found

During the initial inspection, our Nissan specialists confirmed the problem our client was experiencing. We always take this first step as we like to be thorough and experience the issue first-hand.

Our experts found no visual signs that the air conditioning system was malfunctioning, so the diagnosis would require a deeper inspection. 

For the next stage of the inspection process, our experts wanted to perform a complete diagnostics test to see if any error codes appeared. This step is often crucial as it can save a lot of time as it points our specialists in the right direction. 

As the Nissan Leaf is an all-electric vehicle, our technicians at Fitch Autos are required to have the necessary knowledge and experience with all Nissans, including electric and hybrid models.

As your local independent Nissan specialist, we have access to the same level of technical information as the main dealerships. This allows us to use the latest information and wiring diagrams to diagnose your vehicle’s problem. 

The diagnosis

Before our experts consulted the Nissan Leaf wiring diagrams, they performed a diagnostic test to see if any fault codes returned. 

Two fault codes were present:

• P31EE – Refrigerant pressure sensor
• B2631 – Sunload sensor

While these fault codes may seem meaningless, to our experts, they’re an X on the map, pointing them in the right direction. 

At Fitch Autos, we use a 15-step diagnostic process to solve any problem your vehicle has during the first visit. With us, you save time, money, and stress.

Now that our Nissan specialists had the diagnostic codes, they could begin testing specific parts to pinpoint the problem. 

Before specific testing took place, our team consulted the Nissan Leaf wiring diagrams. From looking at the wiring layout, it was clear that the pressure sensor was connected to the air conditioning and heating. 

As the two areas are connected, our experts wanted to test the pressure sensor wiring. 

To do so, an oscilloscope was used. 

An oscilloscope is a specialised tool that shows the voltage of a vehicle’s electrical components. By analysing these readings, our technicians can pinpoint the cause of the air conditioning issue.

The readings showed that the air conditioning pressure sensor wasn’t working as it should, indicating that it was faulty. 

The use of an oscilloscope is something many other garages wouldn’t have done. Luckily, our client brought their Nissan to our experts, where we’re always thorough. 

As the air conditioning pressure sensor appeared to be the leading cause of the problem, it was clear that it would need to be replaced.

Fixing the Nissan Leaf

Now that our Nissan experts had identified the cause of the faulty air conditioning, we informed the client of our findings. Together, we discussed the problems at hand and our recommendations. 

At Fitch Autos, you’re always in the know. We only begin working on your vehicle once you give us the green light. You’re in total control from start to finish. 

Once the client had agreed to our recommendations, our Nissan experts got to work. 

We sourced a genuine Nissan replacement part and solved the air conditioning fault. 

As your local Nissan specialists, we only use genuine or high-quality Nissan parts for all maintenance and repairs, guaranteeing your Nissan receives the quality it needs to perform optimally.

Once the damaged pressure sensor had been replaced, we performed a complete air conditioning service to ensure the client’s air con system was in peak health. We then cleared all faults and re-tested the vehicle. 

All fault codes had cleared, and the client’s Nissan Leaf’s air conditioning system was fully working once again. 

Our client was pleased to have their Nissan Leaf back in peak condition with no air conditioning problems. They were even happier to see that we solved the issue the day they brought their vehicle to us.

At Fitch Autos, we have a quicker turnaround than the main Nissan dealerships, and you even get better than dealership value with us. 

What more could you ask for?

Needless to say, the client left our garage pleased with the level of care and value they’d received.
