2008 Ford Expedition Blower Motor Not Working [How To Fix It]

Your 2008 Ford Expedition’s blower motor is responsible for circulating air through the cabin, which is essential for keeping you cool and comfortable on hot days. If your blower motor isn’t working, it can be a major inconvenience. You may find yourself sweating and uncomfortable, even when the outside temperature is mild. In addition, a malfunctioning blower motor can also be a safety hazard, as it can reduce visibility by fogging up the windows.

In this guide, we’ll walk you through the steps to troubleshoot a 2008 Ford Expedition blower motor that isn’t working. We’ll provide you with the information you need to identify the problem and fix it yourself, or take your vehicle to a qualified mechanic.

What Causes a 2008 Ford Expedition Blower Motor to Not Work

There are a number of different things that can cause a 2008 Ford Expedition blower motor to not work. Some of the most common causes include

A blown fuse
A faulty blower motor resistor
A bad blower motor
A wiring problem

Why 2008 Ford Expedition Blower Motor Not Working

Blower Motor Fuse

The blower motor fuse is a 20-amp fuse located in the under-hood fuse box. If the fuse is blown, the blower motor will not work. To check the fuse, use a multimeter to set to the continuity setting. Disconnect the blower motor connector and insert the multimeter leads into the fuse terminals. If the multimeter reads continuity, the fuse is good. If the multimeter does not read continuity, the fuse is blown and needs to be replaced.

Blower Motor Relay

The blower motor relay is a 12-volt relay located in the under-hood fuse box. If the relay is faulty, the blower motor will not work. To check the relay, use a multimeter to set to the continuity setting. Disconnect the relay connector and insert the multimeter leads into the relay terminals. If the multimeter reads continuity, the relay is good. If the multimeter does not read continuity, the relay is faulty and needs to be replaced.

Blower Motor Control Module

The blower motor control module (BCM) is a electronic control unit (ECU) that controls the speed of the blower motor. If the BCM is faulty, the blower motor will not work. To check the BCM, use a scan tool to read the BCM codes. If there are any BCM codes, the BCM is faulty and needs to be replaced.

Blower Motor

The blower motor is an electric motor that drives the blower fan. If the blower motor is faulty, the blower motor will not work. To check the blower motor, use a multimeter to set to the resistance setting. Disconnect the blower motor connector and insert the multimeter leads into the motor terminals. If the multimeter reads infinite resistance, the blower motor is faulty and needs to be replaced.

How to Troubleshoot: 2008 Ford Expedition Blower Motor Not Working

The blower motor in your 2008 Ford Expedition is responsible for circulating air through the cabin. If the blower motor is not working, you will not be able to get any airflow from the vents. This can be a major inconvenience, especially during the hot summer months.

There are a few different things that could cause the blower motor to stop working. In this article, we will walk you through the steps to troubleshoot the problem and get your blower motor working again.

Tools and Materials

You will need the following tools and materials to troubleshoot the blower motor:

A voltmeter
A test light
A set of metric wrenches
A Phillips head screwdriver
A flathead screwdriver

Step 1: Check the Fuse

The first thing you should do is check the fuse for the blower motor. The fuse is located in the passenger-side fuse box.

To check the fuse, remove the fuse cover from the fuse box. Find the fuse that is labeled Blower Motor. Use the voltmeter to check the fuse. If the fuse is blown, replace it with a new fuse that has the same amperage rating.

Step 2: Check the Blower Motor Relay

If the fuse is not blown, the next thing you should check is the blower motor relay. The relay is located in the under-hood fuse box.

To check the relay, remove the relay from the fuse box. Use the test light to check the relay. If the test light lights up when you turn the key to the On position, the relay is working properly. If the test light does not light up, the relay is bad and needs to be replaced.

Step 3: Check the Blower Motor

If the fuse and relay are both good, the next thing you should check is the blower motor itself.

To check the blower motor, disconnect the electrical connector from the blower motor. Use the voltmeter to check the voltage at the connector. If you have power at the connector, the blower motor is bad and needs to be replaced. If you do not have power at the connector, there is a problem with the wiring between the fuse box and the blower motor.

Step 4: Repair the Wiring

If you find a problem with the wiring, you will need to repair the wiring before you can replace the blower motor.

To repair the wiring, you will need to find the damaged wire and splice in a new wire. You can also use a wire repair kit to repair the damaged wire.

Step 5: Replace the Blower Motor

Once you have repaired the wiring, you can replace the blower motor.

To replace the blower motor, disconnect the electrical connector from the old blower motor. Remove the old blower motor from the vehicle. Install the new blower motor in the vehicle. Connect the electrical connector to the new blower motor.

Conclusion

By following these steps, you can troubleshoot a 2008 Ford Expedition blower motor that is not working. If you have any questions, you can always consult a qualified mechanic.
