Symptoms
When the AC in your Nissan Leaf isn’t working properly, there are a few symptoms that can help you figure out what is wrong. When your car isn’t getting cool air from the vents, it’s difficult to notice.
If you feel a decrease in cabin temperature when driving over 30 MPH, it could be a sign that your AC isn’t working properly.

If there is a clog in this coil, it will cause the system to not cool your car. If this happens, it can be fixed by changing out the evaporator coil, which is fairly easy to do yourself.
You can also have this replaced by a professional if you are not comfortable doing it yourself.
Another reason that your AC might not be working properly is because of a bad circuit board in your unit.
This can happen when you have an overcharged battery and lose power while driving, which can cause all the electrical components in your car to fail when they lose power.
If you notice any flickering lights on your dash or feel you have lost power while driving, there could be a problem with one of these components in your car.
