Rear Ac Not Working Ford Expedition [Proven Fixes!]

Do you own a Ford Expedition and your rear AC is not working You are not alone. This is a common problem that can be frustrating and inconvenient. But don’t worry, I’m here to help. In this guide, I will walk you through the steps to troubleshoot the issue and get your rear AC working again. So, if you’re ready, let’s get started!

Why Rear Ac Not Working Ford Expedition

Bad Blend Door Actuator

The blend door actuator is responsible for controlling the airflow between the front and rear vents. If the actuator is faulty, it may not be able to move the blend door properly, which can prevent cold air from reaching the rear of the vehicle.

Faulty Thermostat

The thermostat controls the flow of coolant through the engine. If the thermostat is stuck open, it can allow coolant to flow through the radiator too quickly, which can prevent the engine from reaching its proper operating temperature. This can lead to the air conditioner not being able to cool the cabin effectively.

Low Refrigerant Level

The refrigerant is a key component of the air conditioning system. If the refrigerant level is too low, the air conditioner will not be able to cool the cabin effectively.

Dirty or Clogged Condenser

The condenser is responsible for removing heat from the refrigerant. If the condenser is dirty or clogged, it can prevent the refrigerant from cooling properly, which can lead to the air conditioner not being able to cool the cabin effectively.

Faulty Expansion Valve

The expansion valve controls the flow of refrigerant into the evaporator. If the expansion valve is faulty, it can allow too much or too little refrigerant to flow into the evaporator, which can lead to the air conditioner not being able to cool the cabin effectively.

Faulty Evaporator

The evaporator is responsible for cooling the air that is blown into the cabin. If the evaporator is faulty, it can prevent the air from being cooled properly, which can lead to the air conditioner not being able to cool the cabin effectively.

How to Troubleshoot: Rear AC Not Working Ford Expedition

The rear air conditioner in your Ford Expedition can help keep you and your passengers cool and comfortable on long road trips or hot summer days. However, if the rear AC stops working, it can be a major inconvenience. There are a few things you can check to troubleshoot the problem and get the rear AC working again.

Possible Causes

There are a few possible causes for a rear AC that is not working. Some of the most common causes include:

A blown fuse
A faulty relay
A bad compressor
A clogged condenser
A restricted evaporator
A faulty blend door actuator

Troubleshooting Steps

To troubleshoot the problem with your rear AC, you will need to do some basic testing. Here are the steps to follow:

1. Check the fuses. The first thing you should do is check the fuses for the rear AC. The fuses are usually located in the fuse box under the hood. If a fuse is blown, it will need to be replaced.
2. Check the relays. The next thing you should check is the relays for the rear AC. The relays are usually located in the fuse box under the hood. If a relay is faulty, it will need to be replaced.
3. Check the compressor. The compressor is the heart of the air conditioning system. It is responsible for compressing the refrigerant gas and sending it through the condenser. If the compressor is not working, the rear AC will not work.
4. Check the condenser. The condenser is located in front of the radiator. It is responsible for cooling the refrigerant gas. If the condenser is clogged, it will not be able to cool the refrigerant gas properly. This will cause the rear AC to not work.
5. Check the evaporator. The evaporator is located in the dashboard. It is responsible for evaporating the refrigerant gas and sending it into the cabin. If the evaporator is restricted, it will not be able to evaporate the refrigerant gas properly. This will cause the rear AC to not work.
6. Check the blend door actuator. The blend door actuator is responsible for controlling the flow of air to the evaporator. If the blend door actuator is faulty, it will not be able to direct the air to the evaporator properly. This will cause the rear AC to not work.

Final Steps

If you have checked all of the possible causes and the rear AC is still not working, you will need to take your vehicle to a qualified mechanic. The mechanic will be able to diagnose the problem and make the necessary repairs.

Prevention

There are a few things you can do to help prevent your rear AC from breaking down:

Keep the air filter clean. A dirty air filter can restrict airflow to the condenser and evaporator. This can cause the rear AC to not work properly.
Have the system serviced regularly. A regular service will help to identify and fix any problems before they become serious.
Use the rear AC sparingly. The rear AC uses more power than the front AC. If you only use the rear AC when you need it, you can help to extend its lifespan.

By following these tips, you can help to keep your rear AC working properly and enjoy cool, comfortable air in the back seat of your Ford Expedition.

FAQs: Rear AC Not Working in Ford Expedition

Why is my rear AC not working in my Ford Expedition?

There are a few possible reasons why your rear AC may not be working. Here are some of the most common causes:

A blown fuse: The fuse for the rear AC may have blown. This is a common problem, and it can be easily fixed by replacing the fuse.

A faulty compressor: The compressor is the heart of the AC system, and if it fails, the AC will not work. A faulty compressor can be diagnosed and repaired by a qualified mechanic.

A leak in the refrigerant lines: The refrigerant lines carry the refrigerant gas throughout the AC system. If there is a leak in the lines, the refrigerant will escape and the AC will not work. A leak can be found and repaired by a qualified mechanic.

A dirty condenser: The condenser is a radiator-like component that helps to cool the refrigerant gas. If the condenser becomes dirty, it can reduce the efficiency of the AC system and cause it to not work properly. The condenser can be cleaned by a qualified mechanic.

How can I fix my rear AC in my Ford Expedition?

If your rear AC is not working, you can try to fix it yourself or you can take it to a qualified mechanic. Here are some steps you can take to fix the problem yourself:

1. Check the fuse for the rear AC. If the fuse is blown, replace it with a new fuse.
2. Check the compressor. If the compressor is not working, you will need to have it repaired or replaced.
3. Check the refrigerant lines for leaks. If there is a leak, you will need to have the leak repaired.
4. Clean the condenser. If the condenser is dirty, you can clean it with a garden hose or a pressure washer.

If you are not comfortable working on your car, you should take it to a qualified mechanic. They will be able to diagnose the problem and fix it quickly and efficiently.
