2017 Ford Expedition AC Fan Not Working: Here’s the Fix!

Do you own a 2017 Ford Expedition and your AC fan isn’t working You’re not alone. This is a common problem that can be frustrating and inconvenient. But don’t worry, there is a solution. In this guide, I’ll walk you through the steps to troubleshoot and fix the problem yourself. So you can get back to enjoying your cool, comfortable ride in no time.

Reasons Why 2017 Ford Expedition Ac Fan Not Working

Here are the reasons:

Bad blower motor

The blower motor is responsible for circulating air through the cabin. If the blower motor is not working, the air conditioner will not be able to cool the cabin. The blower motor can be checked by removing the air filter and listening for the motor running. If the motor is not running, it will need to be replaced.

Bad blower motor resistor

The blower motor resistor controls the speed of the blower motor. If the resistor is bad, the blower motor may not be able to reach its full speed, which will reduce the amount of air that is circulated through the cabin. The blower motor resistor can be checked by using a multimeter to measure the resistance across the terminals. If the resistance is too high or too low, the resistor will need to be replaced.

Bad wiring

The blower motor is wired to the car’s electrical system. If there is a problem with the wiring, the blower motor may not be able to receive power. The wiring can be checked by using a multimeter to check for continuity between the blower motor and the fuse box. If there is no continuity, the wiring will need to be repaired or replaced.

Bad climate control module

The climate control module is responsible for controlling the temperature and airflow of the air conditioner. If the climate control module is bad, the air conditioner may not be able to cool the cabin properly. The climate control module can be checked by using a diagnostic scanner to read the codes. If there are any codes related to the climate control module, it will need to be replaced.

How to Troubleshoot: 2017 Ford Expedition AC Fan Not Working

Check the Blower Motor

If your 2017 Ford Expedition’s AC fan is not working
the first thing to check is the blower motor. The blower motor is responsible for pushing air through the vents of your vehicle’s HVAC system. Start by turning the fan speed to its highest setting. If you don’t hear the blower motor running
there may be an issue with the motor itself or its electrical connections.

Inspect the Blower Motor Resistor

The blower motor resistor controls the speed of the blower motor. If the resistor is faulty
it can cause the fan to stop working at certain speeds. The blower motor resistor is typically located near the blower motor under the dashboard. Use a multimeter to test the resistor for continuity. If there’s no continuity
the resistor may need to be replaced.

Check the HVAC Control Module

The HVAC control module
also known as the blower motor control module
is responsible for regulating the fan speed based on the input from the HVAC control panel. If the module fails
it can prevent the fan from working. Use a diagnostic scan tool to check for any trouble codes related to the HVAC control module. If there are any codes present
further diagnosis may be required.

Inspect the Fuses and Relays

Faulty fuses or relays can also cause the AC fan to stop working. Consult your vehicle’s owner’s manual to locate the fuse box and identify the fuse and relay associated with the AC fan. Use a test light or multimeter to check for power at the fuse and relay. If there’s no power
the fuse or relay may need to be replaced.

Check for Wiring Issues

Inspect the wiring that connects the blower motor
resistor
and control module for any signs of damage or corrosion. A visual inspection can help identify any obvious issues with the wiring. Use a wiring diagram for your vehicle to trace the wiring and check for continuity using a multimeter.

Conclusion

Troubleshooting a 2017 Ford Expedition’s AC fan that’s not working requires a systematic approach to identify and address the underlying issue. By checking the blower motor
blower motor resistor
HVAC control module
fuses and relays
and wiring
you can diagnose the problem and take the necessary steps to restore proper function to your vehicle’s AC system.

FAQs: 2017 Ford Expedition AC Fan Not Working

Why is my 2017 Ford Expedition AC fan not working?

There are a few possible reasons why your 2017 Ford Expedition AC fan may not be working. Here are some of the most common causes:

A blown fuse: The most common cause of a non-working AC fan is a blown fuse. To check the fuses, open the fuse box located under the hood of your vehicle. Look for a fuse labeled AC or A/C. If the fuse is blown, replace it with a new fuse of the same amperage.

A faulty blower motor: The blower motor is responsible for circulating air through the vents. If the blower motor is faulty, it will not be able to generate enough airflow to cool the cabin. To test the blower motor, turn on the AC and listen for a buzzing sound. If you do not hear a buzzing sound, the blower motor may be faulty.

A clogged air filter: A clogged air filter can restrict airflow to the blower motor, causing it to overheat and fail. To check the air filter, remove the air filter housing located under the hood of your vehicle. Remove the air filter and inspect it for dirt, debris, or other obstructions. If the air filter is clogged, replace it with a new one.

A faulty control module: The control module is responsible for sending signals to the blower motor. If the control module is faulty, it may not be able to send the correct signals to the blower motor, causing it to malfunction. To test the control module, you will need to take your vehicle to a qualified repair shop.

What should I do if my 2017 Ford Expedition AC fan is not working?

If your 2017 Ford Expedition AC fan is not working, you should first try to troubleshoot the problem yourself. Here are some steps you can take:

Check the fuses: First, check the fuses to make sure they are not blown. If a fuse is blown, replace it with a new fuse of the same amperage.

Test the blower motor: Next, test the blower motor to make sure it is working properly. To do this, turn on the AC and listen for a buzzing sound. If you do not hear a buzzing sound, the blower motor may be faulty.

Check the air filter: If the blower motor is not working, check the air filter to make sure it is not clogged. A clogged air filter can restrict airflow to the blower motor, causing it to overheat and fail.

Check the control module: If the blower motor and air filter are not the problem, you may need to check the control module. The control module is responsible for sending signals to the blower motor. If the control module is faulty, it may not be able to send the correct signals to the blower motor, causing it to malfunction.

If you are unable to troubleshoot the problem yourself, you should take your vehicle to a qualified repair shop.
