Ford Expedition Air Conditioner Not Working [Reasons + Fixed]

Do you own a Ford Expedition and your air conditioner isn’t working You’re not alone. This is a common problem, and it can be frustrating and inconvenient. But don’t worry, there is a solution. In this guide, I will walk you through the steps to troubleshoot and fix your Ford Expedition’s air conditioner. I’ll also provide some tips on how to prevent this problem from happening again.

Why Ford Expedition Air Conditioner Not Working

Low Refrigerant Level

The most common cause of a Ford Expedition air conditioner not working is a low refrigerant level. The refrigerant is a gas that circulates through the air conditioner and absorbs heat from the interior of the vehicle. If the refrigerant level is low, the air conditioner will not be able to cool the air effectively.

Faulty Thermostat

The thermostat controls the flow of refrigerant through the air conditioner. If the thermostat is faulty, it may not be able to open properly, which will prevent the refrigerant from flowing through the system. This will cause the air conditioner to not work properly.

Faulty Condenser

The condenser is a radiator-like device that cools the refrigerant after it has passed through the evaporator. If the condenser is faulty, it may not be able to cool the refrigerant properly, which will cause the air conditioner to not work properly.

Faulty Evaporator

The evaporator is a heat exchanger that converts the refrigerant from a liquid to a gas. If the evaporator is faulty, it may not be able to convert the refrigerant properly, which will cause the air conditioner to not work properly.

Faulty Expansion Valve

The expansion valve controls the flow of refrigerant into the evaporator. If the expansion valve is faulty, it may not be able to control the flow of refrigerant properly, which will cause the air conditioner to not work properly.

Faulty Compressor

The compressor is the heart of the air conditioner. It compresses the refrigerant and circulates it through the system. If the compressor is faulty, it will not be able to compress the refrigerant properly, which will cause the air conditioner to not work properly.

How to Troubleshoot: Ford Expedition Air Conditioner Not Working

Your Ford Expedition’s air conditioner is one of the most important features on a hot summer day. When it’s not working properly, it can make driving uncomfortable and even dangerous. There are a few common reasons why an Expedition’s air conditioner might not be working, and most of them are relatively easy to fix.

In this article, we’ll walk you through the steps to troubleshoot a Ford Expedition air conditioner that’s not working. We’ll cover everything from checking the fuses to replacing the compressor. By the end of this article, you’ll be able to get your Expedition’s air conditioner up and running again in no time.

Step 1: Check the fuses

The first thing you should do if your Expedition’s air conditioner isn’t working is check the fuses. The fuses for the air conditioner are located in the fuse box under the hood.

To check the fuses, you’ll need a fuse puller. You can find these at most auto parts stores. Once you have the fuse puller, open the fuse box and locate the fuses for the air conditioner. There will be two fuses, one for the compressor and one for the blower motor.

To check the fuses, simply remove them from the fuse box and look for any signs of damage. If the fuses are blown, they will be blackened or melted. If you find a blown fuse, replace it with a new one that has the same amperage rating.

Step 2: Check the wiring

Once you’ve checked the fuses, the next step is to check the wiring. The wiring for the air conditioner is located under the hood and in the cabin.

To check the wiring, you’ll need a voltmeter. You can find these at most auto parts stores. Once you have the voltmeter, start by checking the wiring under the hood.

Locate the wiring harness that connects to the compressor. There will be two wires, one red and one black. Using the voltmeter, check the voltage between the two wires. The voltage should be around 12 volts. If there is no voltage, there is a problem with the wiring.

Next, check the wiring in the cabin. Locate the wiring harness that connects to the blower motor. There will be two wires, one red and one black. Using the voltmeter, check the voltage between the two wires. The voltage should be around 12 volts. If there is no voltage, there is a problem with the wiring.

Step 3: Check the compressor

If the fuses and wiring are all good, the next step is to check the compressor. The compressor is located under the hood.

To check the compressor, you’ll need a pressure gauge. You can find these at most auto parts stores. Once you have the pressure gauge, connect it to the high-pressure side of the compressor.

Start the engine and turn on the air conditioner. The compressor should start to run. The pressure gauge should show a reading of around 250 psi. If the pressure is too low, there is a problem with the compressor.

Step 4: Replace the compressor

If the compressor is bad, you’ll need to replace it. You can find compressors at most auto parts stores. Once you have the compressor, follow the instructions in the owner’s manual to replace it.

Conclusion

Troubleshooting a Ford Expedition air conditioner that’s not working can be a bit tricky, but it’s definitely doable. By following the steps in this article, you should be able to get your Expedition’s air conditioner up and running again in no time.

Additional tips

If you’re not comfortable working on your own car, you can always take it to a qualified mechanic.
Make sure to use the right type of refrigerant when you’re refilling the air conditioner.
Be careful not to overfill the air conditioner. Doing so can damage the compressor.
If you live in a hot climate, it’s a good idea to have your air conditioner serviced regularly. This will help to prevent problems from occurring.

FAQs: Ford Expedition Air Conditioner Not Working

Why is my Ford Expedition air conditioner not working?

There are a few possible reasons why your Ford Expedition air conditioner may not be working. Here are some of the most common causes:

A blown fuse: The most common cause of a non-working air conditioner is a blown fuse. To check the fuses, open the fuse box and look for a fuse that is blown out. If you find a blown fuse, replace it with a new one that is the same amperage.

A faulty compressor: The compressor is the heart of the air conditioner system. If the compressor is not working, the air conditioner will not be able to produce cold air. To check the compressor, you can listen for a whining noise coming from the engine bay. If you hear a whining noise, it is likely that the compressor is not working properly.

A clogged condenser: The condenser is located in front of the radiator and helps to cool the refrigerant. If the condenser is clogged, the air conditioner will not be able to produce cold air. To check the condenser, you can look for a build-up of dirt or debris on the fins. If you see a build-up of dirt or debris, you can clean it off with a garden hose.

A faulty evaporator: The evaporator is located inside the cabin and helps to cool the air before it is blown out of the vents. If the evaporator is not working properly, the air conditioner will not be able to produce cold air. To check the evaporator, you can use a thermal imaging camera to look for hot spots. If you see hot spots, it is likely that the evaporator is not working properly.

A low refrigerant charge: The air conditioner system uses refrigerant to cool the air. If the refrigerant charge is too low, the air conditioner will not be able to produce cold air. To check the refrigerant charge, you can use a refrigerant manifold gauge. If the refrigerant charge is low, you can add more refrigerant to the system.

How do I fix my Ford Expedition air conditioner?

To fix your Ford Expedition air conditioner, you will need to identify the cause of the problem. Once you have identified the cause, you can follow the steps below to fix the problem.

Blown fuse: To fix a blown fuse, simply replace the fuse with a new one that is the same amperage.

Faulty compressor: To fix a faulty compressor, you will need to replace the compressor.

Clogged condenser: To clean a clogged condenser, you can use a garden hose to rinse off the dirt and debris.

Faulty evaporator: To fix a faulty evaporator, you will need to replace the evaporator.

Low refrigerant charge: To add more refrigerant to the system, you will need to use a refrigerant manifold gauge.

How much does it cost to fix a Ford Expedition air conditioner?

The cost of fixing a Ford Expedition air conditioner will vary depending on the cause of the problem. The following are some general cost estimates:
