Why Ford Expedition Ac Not Working

Low Refrigerant Level

The most common cause of a Ford Expedition AC not working is a low refrigerant level.
The refrigerant is a gas that helps to cool the air inside the vehicle.
If the refrigerant level is too low, the AC will not be able to cool the air effectively.
You can check the refrigerant level with a refrigerant pressure gauge.
If the level is low, you can add more refrigerant to the system.

Faulty AC Compressor

The AC compressor is a pump that circulates the refrigerant through the AC system.
If the compressor is faulty, it will not be able to circulate the refrigerant and the AC will not work.
You can test the compressor by listening for a whining noise when the AC is turned on.
If you hear a whining noise, the compressor is likely faulty and will need to be replaced.

Faulty AC Condenser

The AC condenser is a radiator-like device that cools the refrigerant before it returns to the evaporator.
If the condenser is faulty, it will not be able to cool the refrigerant and the AC will not work.
You can test the condenser by feeling the temperature of the condenser lines.
If the lines are hot, the condenser is likely faulty and will need to be replaced.

Faulty AC Evaporator

The AC evaporator is a device that cools the air inside the vehicle.
If the evaporator is faulty, it will not be able to cool the air and the AC will not work.
You can test the evaporator by feeling the temperature of the air coming out of the vents.
If the air is not cold, the evaporator is likely faulty and will need to be replaced.

Faulty AC Control Unit

The AC control unit is a computer that controls the operation of the AC system.
If the control unit is faulty, it will not be able to properly control the AC system and the AC will not work.
You can test the control unit by using a diagnostic tool to read the codes.
If there are any codes, the control unit is likely faulty and will need to be replaced.

How to Troubleshoot: Ford Expedition AC Not Working

Your Ford Expedition’s air conditioner is a vital part of keeping you cool and comfortable during hot weather. However, if your AC isn’t working properly, it can be a major inconvenience. There are a number of things that could be causing your AC to malfunction, but don’t worry, we’re here to help. In this article, we’ll walk you through the steps of troubleshooting a Ford Expedition AC that’s not working. We’ll also provide tips on how to prevent future problems.

Step 1: Check the fuses

The first thing you should do is check the fuses for your AC. To do this, locate the fuse box in your Expedition. It’s usually located under the hood or in the passenger compartment. Once you’ve found the fuse box, look for a fuse labeled AC or A/C. If the fuse is blown, replace it with a new one.

Step 2: Check the compressor clutch

The compressor clutch is a small, electric motor that engages the compressor. If the compressor clutch isn’t working properly, it won’t be able to engage the compressor, and your AC won’t work. To check the compressor clutch, you’ll need to use a voltmeter. First, turn on the AC and set the temperature to the coldest setting. Then, put the voltmeter on the battery terminals. With the engine running, the voltmeter should read between 12 and 14 volts. If the voltage drops when you turn on the AC, it’s likely that the compressor clutch is bad.

Step 3: Check the condenser

The condenser is a radiator-like device that cools the refrigerant gas. If the condenser is dirty or clogged, it won’t be able to effectively cool the refrigerant gas, and your AC won’t work as well. To check the condenser, you’ll need to remove the air filter housing. Once you’ve removed the air filter housing, you’ll be able to see the condenser. Look for any signs of damage or blockage. If the condenser is dirty, you can clean it with a garden hose.

Step 4: Check the evaporator

The evaporator is a small, metal device that’s located inside the dashboard. The evaporator is responsible for cooling the air that comes out of the vents. If the evaporator is dirty or clogged, it won’t be able to effectively cool the air, and your AC won’t work as well. To check the evaporator, you’ll need to remove the glove box. Once you’ve removed the glove box, you’ll be able to see the evaporator. Look for any signs of damage or blockage. If the evaporator is dirty, you can clean it with a vacuum cleaner.

Step 5: Check the refrigerant level

The refrigerant is a type of gas that’s used to cool the air in your AC system. If the refrigerant level is too low, your AC won’t work properly. To check the refrigerant level, you’ll need to use a refrigerant manifold gauge. First, turn off the AC and disconnect the battery. Then, attach the refrigerant manifold gauge to the high and low pressure service ports on the AC compressor. With the engine running, the high pressure gauge should read between 200 and 300 psi. The low pressure gauge should read between 30 and 50 psi. If the refrigerant level is too low, you’ll need to add refrigerant to the system.

Step 6: Inspect the AC lines

The AC lines are the hoses that carry the refrigerant gas through the AC system. If the AC lines are damaged or leaking, they can cause your AC to malfunction. To inspect the AC lines, you’ll need to look for any signs of damage or leaks. If you find any damage or leaks, you’ll need to have the AC lines repaired or replaced.

Step 7: Inspect the AC controls

The AC controls are the switches and knobs that you use to operate the AC system. If the AC controls are not working properly, they can prevent your AC from working. To inspect the AC controls, you’ll need to look for any signs of damage or wear. If you find any damage or wear, you’ll need to have the AC controls repaired or replaced.

Step 8: Reset the AC system
