Your Ford Expedition Heater Is Not Working? Here’s Why!

Do you have a Ford Expedition whose heater isn’t working You’re not alone. This is a common problem, and it can be a real pain. Not only is it uncomfortable to be cold in your car, but it can also be dangerous if the temperature drops too low. In this guide, we’ll walk you through the steps to troubleshoot the problem and get your heater working again. We’ll also provide some tips on how to prevent this issue from happening in the future.

Reasons Why Ford Expedition Heater Not Working

Here are the reasons:

No Heat

Thermostat is stuck closed:
The thermostat is a valve that controls the flow of coolant through the engine. If the thermostat is stuck closed, coolant will not flow through the heater core and the cabin will not heat up.

Heater core is clogged:
The heater core is a radiator that transfers heat from the engine coolant to the cabin air. If the heater core is clogged, it will not be able to transfer heat effectively and the cabin will not heat up.

Blend door actuator is stuck:
The blend door actuator controls the position of the blend door, which directs air from the heater core or the A/C evaporator to the cabin. If the blend door actuator is stuck, it will not be able to direct air to the cabin and the cabin will not heat up.

Electrical problem:
There could be a problem with the wiring or the control module for the heater. This could cause the heater to not work properly or at all.

Bleeding the Heater Core

If the heater core is the cause of the problem, you will need to bleed the heater core to remove any air bubbles that may be trapped inside. To do this, follow these steps:

1. Park the vehicle on a level surface.
2. Turn the engine off and allow it to cool down.
3. Remove the radiator cap.
4. Locate the heater hoses that connect to the heater core.
5. Connect a hose to the heater hose that is closest to the engine.
6. Place the other end of the hose in a bucket.
7. Start the engine and allow it to run for a few minutes.
8. Turn off the engine and allow it to cool down.
9. Disconnect the hose from the heater hose.
10. Reinstall the radiator cap.

The heater core should now be bled of air bubbles. If the heater still does not work, you may need to have the heater core replaced.

How to Troubleshoot: Ford Expedition Heater Not Working

Your Ford Expedition’s heater is an important part of keeping you warm and comfortable during the winter months. If your heater isn’t working properly, it can be a real pain. There are a few different things that could be causing the problem, and it’s important to troubleshoot the issue so that you can get your heater back up and running as soon as possible.

In this article, we’ll walk you through the steps of troubleshooting a Ford Expedition heater that’s not working. We’ll cover everything from checking the fuses to replacing the blower motor. By the end of this article, you’ll be able to identify the problem and fix it yourself.

Step 1: Check the fuses

The first thing you should do is check the fuses in your Ford Expedition’s heater system. The fuses are located in the fuse box under the hood. There should be a fuse labeled HEATER or HEATER BLOWER. Check to make sure that the fuse is not blown. If the fuse is blown, you’ll need to replace it with a new one.

Step 2: Check the blower motor

The blower motor is responsible for blowing air through the heater vents. If the blower motor is not working, your heater will not work. To check the blower motor, you’ll need to remove the glove box. Once the glove box is removed, you’ll be able to access the blower motor. Turn the key to the ON position and listen for the blower motor. If you don’t hear the blower motor running, it’s likely that the motor is bad and needs to be replaced.

Step 3: Check the heater control valve

The heater control valve is responsible for directing coolant from the engine to the heater core. If the heater control valve is stuck closed, coolant will not flow to the heater core and your heater will not work. To check the heater control valve, you’ll need to remove the heater hoses from the valve. Turn the key to the ON position and look for coolant flowing through the hoses. If you don’t see coolant flowing, it’s likely that the heater control valve is stuck closed and needs to be replaced.

Step 4: Check the heater core

The heater core is a small radiator that is located in the passenger compartment. The heater core is responsible for transferring heat from the coolant to the air that flows through the heater vents. If the heater core is clogged or damaged, your heater will not work properly. To check the heater core, you’ll need to remove the heater housing. Once the heater housing is removed, you’ll be able to see the heater core. Look for any signs of damage or blockage. If you see any damage or blockage, the heater core will need to be replaced.

Step 5: Check the blend door actuator

The blend door actuator is responsible for controlling the airflow through the heater core. If the blend door actuator is not working properly, your heater may not be blowing hot air. To check the blend door actuator, you’ll need to remove the dashboard. Once the dashboard is removed, you’ll be able to access the blend door actuator. Turn the key to the ON position and use a voltmeter to check for voltage at the blend door actuator. If you don’t have voltage at the blend door actuator, it’s likely that the actuator is bad and needs to be replaced.

Conclusion

These are just a few of the things that could be causing your Ford Expedition’s heater to not work. If you’ve checked all of these things and your heater still isn’t working, it’s time to take your vehicle to a qualified mechanic.
