Don’t worry, there are a few things that you can do to make sure that your AC system works correctly.

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.

You may also notice condensation in your windshield after driving over a certain speed range and hear air whistling from inside the vents while they are operating.

Causes

When the AC on your Nissan Leaf isn’t working properly, there are a few things that could cause it. The most common reason for this is a clogged or dirty evaporator coil. This is the small metal tube that cools the refrigerant through the AC system.

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.

Fixing

If you suspect that your AC system is broken, the first thing that you should do is start by checking for a loose connection or damaged wire in the unit.

If there is a loose connection or damaged wire, this can cause the AC to not work properly. This can also cause the fan in your car to not work as well, which could cause your cabin temperature to go down while driving.

If you suspect that there is a loose connection or damaged wire in your unit, you can try to tighten it.

You can also try changing out the evaporator coil if you suspect that this is the problem. This is a fairly simple task and shouldn’t take you too long to do.

You can check for a loose connection or damaged wire by unplugging your unit and looking for anything that looks wrong with the wires inside of it.

Another thing you can do to fix Nissan Leaf AC not working is to try cleaning the condenser. This is the part of your unit that cools the refrigerant inside of it. You can remove this with a can of compressed air and a brush, which should make this fairly easy to do.

If you still notice that your AC isn’t working properly, contact a professional for help.
