Ford Excursion heater not working – causes and diagnosis

The heater in Ford Excursion ensures comfortable temperature in the passenger compartment when the weather is chilly. There are many reasons for poor heating performance in Excursion, which are explained in this article.

The heater may stop working in Ford Excursion due to low coolant level or air in the cooling system, clogged heater core, bad thermostat, faulty blend door actuator, bad water pump, dirty cabin air filter, bad blower motor, or HVAC control unit malfunction.

1. Low coolant or air in the cooling system

Low coolant level or air in the cooling system can cause the heater to stop working properly in Excursion. If the cooling system is not full and bled properly, the water pump will not be able to push the coolant around the system efficiently.

The heating system in Excursion uses hot coolant or antifreeze from the engine block to heat the interior of the vehicle. The hot coolant is pumped through the heater core located behind the dashboard. When you turn on the heating, air gets blown through the heater core, warming the air in the cabin. If there is air trapped inside the heater core, the coolant will not be able to flow through it properly. Since the heater core is usually slightly higher, the air will accumulate in there first. By filling and properly bleeding the system the heat should come back.

Sloshing water sound

Low coolant level or air in the heater core can sometimes cause sloshing sound from behind the dashboard when the engine is running. The sound is most prominent right after you start the vehicle.

Check coolant level

Checking coolant level in Excursion is a fairly some job. You just have to locate the coolant overflow reservoir and inspect the level of coolant in it. If the coolant level is low, open the cap and pour some coolant into the tank until it is between minimum and maximum mark.

2. Clogged heater core

Clogged heater core is one of the leading causes of heating not working in Ford Excursion. The design of the heater core is similar to the radiator, it has narrow internal channels through which hot coolant flows. Over time, the heater core can begin to rust or mineral deposits can form in these channels, blocking the flow of the coolant.

How to check if the heater core is clogged

You don’t have to remove the heater core in your Excursion to check if it is clogged. Locate two rubber hoses that connect to the heater core through the firewall area. Feel both the rubber lines going in and out of the heater core after the engine has warmed up. Both should be hot. If one is hot and the other is cold, you have a plugged heater core.

Flush the heater core

Before you consider replacing the heater core in your Excursion, it is recommended to flush the existing heater core. Flushing is done by pushing water through the outlet hose of the heater core and draining the gunk from the inlet hose. There are flush kits available in the market that can help you do the job yourself.

3. Bad thermostat

Thermostat is a part of the cooling system in Ford Excursion which ensures that the engine reaches its optimal operating temperature as quickly as possible and maintain it under all operating conditions.

Thermostat is stuck open

When you start your Excursion when the engine is cold, the thermostat cuts off flow of coolant through the radiator in order to quickly reach the optimal engine operating temperature. But if the thermostat has developed a defect and is stuck to open position, the coolant will continuously flow through the radiator and the engine may take a long time to reach its optimal operating temperature.

Heater takes a long time to blow hot air

Since the heating system in Excursion relies on the hot coolant from the engine to heat the interior, the heater will blow cold air until the engine reaches its normal operating temperature. But if the weather is too cold, the engine may never reach its optimal operating temperature with a stuck open thermostat. Your vehicle may also consume more fuel than normal.

5. Bad water pump

The water pump is the heart of the cooling system in Excursion responsible for pumping coolant throughout the system and cooling the engine. If the water pump has worn out and the coolant is not being circulated as effectively as it used to, it can cause the heater to stop working properly because there’s less coolant available to transfer heat between the engine and the heater core.

Water pumps usually last for more than 100,000 miles, but they can fail at any time. A bad water pump will not only cause poor heating, but can also result in engine damage due to overheating. Therefore it is important to diagnose a failing water pump at early stages to avoid expensive repairs later on.

6. Faulty blend door actuator

Blend door actuator plays a role in controlling the temperature inside your Excursion. If the blend door actuator fails to fully open the blend door towards the heater core, it will result in poor heating performance.

The most common symptom of a faulty blend door actuator in Ford Excursion is a slight clicking sound (or other unusual noise) repeatedly coming from under the dashboard. The sound will be most prominent for a few seconds when you turn on the air conditioning or adjust the temperature.

Symptom: knocking sound

A knocking noise from behind the dashboard could be an indicator of a bad blend door actuator in your Excursion. The sound is something like a light tapping on the door and it typically happens when you turn on/off the air conditioning system or start the engine.

Symptom: creaking sound

One side hot, other side cold.

A common symptom of a faulty blend door actuator in vehicles with dual zone climate control system is one side blowing hot air while the other side is blowing cold air.

Replace the faulty part

A bad blend door actuator usually cannot be repaired and must be replaced with a new one. Due to the complexity of the replacement job, it is not recommended as a DIY project. The blend door actuator may require recalibration after replacement.

7. Dirty cabin air filter

Dirty cabin air filter is the leading cause of weak heater airflow in Ford Excursion. The pollen filter, also known as the cabin air filter or microfilter, is responsible for filtering the air that the passengers breathe in the cabin. A dirty filter causes the overall ventilation of the interior to deteriorate resulting in reduced heating and airflow.

There is no fixed time for replacing the cabin air filter, but most manufacturers recommend a change after 10,000-20,000 miles. If you drive your vehicle in dusty or polluted environment, the filter can get dirty much sooner than manufacturer’s recommendation. Additionally, if you drive your Excursion with AC system set to fresh outside air most of the time, your cabin air filter will get dirty much sooner as compared to air recirculation mode.

Replace the filter at the start of every winter for optimal performance

It is generally recommended to replace the cabin air filter every year at the start of the winter season. Spring and summer seasons are hard on the cabin air filter because of pollen and bugs, and in the fall they can get clogged with leaf debris. This gives you a fresh start for the winter, improves defroster performance, and reduces chances of mold or mildew growth.

Can you clean a dirty cabin air filter?

Instead of changing the cabin air filter in Excursion, it is often recommended to first clean the filter. This can be done, for example, with a vacuum cleaner or a compressed air system, removing at least a large part of the visible dirt particles. Unfortunately, this procedure does not allow you to get into the deeper layers of the filter. Therefore, the filter performance will not increase significantly even after cleaning. As a rule, there is no avoiding a change if the filter is dirty.

8. Sluggish blower motor

If the blower motor in your Excursion is not spinning fast enough either due to an internal defect or due to a fault in the resistor/control module, the airflow from the AC vents will be weaker and the heating performance will be degraded.

When a blower motor goes bad, it usually makes unusual noises when in operation, and the passengers may feel reduced airflow from the air vents. Keep in mind that reduced airflow doesn’t always indicate a problem with the blower motor, as it can also happen due to a clogged cabin air filter, dirty evaporator, or a bad mode door actuator. So, all of them must be inspected when diagnosing poor airflow.

9. Dead blower motor (no airflow)

If there is no air flow from the air vents in the dashboard when you turn on the heater in your Ford Excursion, it means the problem is related to the fan or blower motor function.

The most common causes for blower motor not working in Ford Excursion are blown fuse, bad relay, resistor or control module malfunction, and faulty blower motor. However, a bad electrical connector or broken wire, or a defect in the climate control unit can also cause the blower motor to stop working.

10. Dirty evaporator

Dirty evaporator can cause weak airflow and reduce the heating performance in Excursion. Although, the evaporator coil is a component of the cooling function of the air-conditioning system, but the air always first passes through the evaporator and then flows over the heater core.

The cabin air filter captures most of the dirt or other airborne particles, but some particles escape and can get lodged on to the evaporator. Over time, these particles build up on the fins and block the air flow through the evaporator, causing reduced air flow in the cabin and poor heating or cooling.

Function of the evaporator in heating mode

When the heater is turned on and the AC turned off, the compressor does not turn on and the evaporator is not cooled. When you press the AC button in heating mode, the compressor turns on and the evaporator cools and dries the air before it enters the heater core. This mode is useful for clearing fog from the windows.

11. Faulty HVAC module

Climate control module is the brain of the air-conditioning system in your Ford Excursion, responsible for controlling all the components in the system. In rare cases, a fault in the climate control unit can cause the heater to stop functioning. This would require a scan tool to confirm correct operation.

12. Blown head gasket

The head gasket is responsible for providing the seal between the engine block and cylinder heads. Its purpose is to seal the combustion gases within the cylinders and to avoid coolant or engine oil leaking into the cylinders. Leaks in the head gasket can cause all sorts of problems in your Excursion including poor heater performance. This is mostly common in older vehicles.

Leaking exhaust gases

A blown head gasket can cause the exhaust gases from the engine to enter the cooling system and plug the heater core. Clearing the air from the heater core will not help until the head gasket has been replaced.

Leaking coolant

A blown head gasket can cause coolant to leak into the combustion chambers and burn off. If your Excursion is losing coolant, that means there is a leak somewhere or it is getting burned up inside the engine.

How to check if head gasket is leaking in Excursion?

You don’t have to go to a workshop to check for a leaking head gasket in your Excursion. There are test kits available in the market in which you just have to insert a tube filled with colored liquid in the radiator (in place of the radiator cap), and then start the engine. If the liquid changes color, then there is a leak in head gasket.

Switch on air recirculation mode

When the outside temperature drops too low, the heating performance may be reduced in Excursion if the air conditioning system is set to outside air. To improve heating efficiency, it is recommended to switch on air recirculation mode. Don’t worry, there is no risk of suffocation, as the air recirculation mode still allows up to approximately 10 percent of the air coming from the air vents to be fresh air from the outside.

There are many reasons why the heater in your Ford Excursion is not working properly. When looking for the reason, you should start with the most obvious causes: low coolant level or air in the cooling system, and clogged heater core.

In any case, it is advisable for laypersons to visit a workshop. A professional mechanic can swiftly diagnose the heating issue for you.

04 Excursion Heater hose replacement on passenger side

• Add to quote

I have an 04 excursion and found a leak on the plastic Y that connects the hoses to the heater core of the front and rear heater. This part also contains the heater control valve that has the vacuum tube plugged into it. It also is attached to the firewall by a zip-tie. There are 3 ends to this hose. 1 end plugs into the metal tube on above the front of the valve cover on the passenger side. Another end plugs into the heater core on the passenger side. (The heater core is located on the passenger side, trying to clarify which side of the heater core). The final (longest) and hidden connection drops down into the abyss. I am pretty sure this connects to the rear heater core. I am not quite sure how to access the connection to the rear heater core for removal. Do I jack the vehicle up and remove the passenger side tire, then remove the covering inside the wheel well to access? Or do I attempt to reach up from underneath the vehicle? I don't think it is feasible to reach up since I wouldn't be able to get hold of it that way. Just wondering if anyone has some insight  

Bumping up to see if anyone knows. Thanks

Russia’s BN800 fast reactor fully fuelled with mox

!{Model.Description}

Beloyarsk 4 was connected to the grid and resumed electricity production after the completing its latest regular maintenance and refuelling outage. It was refuelled with mox fuel assemblies (FAs) produced at the Mining and Chemical Combine (MCC) in Zheleznogorsk, Krasnoyarsk Territory). Unlike the enriched uranium FAs traditionally used in NPPs, the raw materials for the production of mox fuel pellets includes plutonium oxide obtained during the processing of used fuel from conventional VVER reactors alongside depleted uranium oxide, obtained by defluorination of depleted uranium hexafluoride (DUHF – “tails" from enrichment production).

The first serial mox-FAs were loaded into the BN-800 core in January 2020. The first complete refuelling of the BN-800 with mox fuel took place in January 2021, and then, over the next two refuellings, all fuel assemblies were gradually replaced with innovative mox assemblies.

Other important work performed during the outage of unit 4 included overhaul of the main circulation pump with the replacement of the removable parts, maintenance and repair of pumps, heat exchangers, steam generators and a turbogenerator. Also, the operational quality control of metal and welded joints of pipelines was carried out as well as tests of the system for monitoring the tightness of shells using a metrological assembly.

“Today, Beloyarsk NPP is one of the flagships bringing the Russian nuclear industry closer to a new technological platform based on a closed nuclear fuel cycle,” said Beloyarsk NPP Director Ivan Sidorov. “The use of mox fuel will make it possible to increase the fuel base of the nuclear power industry tenfold. And most importantly, in the BN-800 reactor, after appropriate processing, used nuclear fuel from other NPPs can be recycled.”

Alexander Ugryumov, Senior Vice President for Scientific and Technical Activities at TVEL said completing conversion of BN-800 to mox fuel is a long-awaited event for the nuclear industry. “For the first time in the history of the Russian nuclear power industry, we will be able to operate a fast neutron reactor with a full load of uranium-plutonium fuel and a closed nuclear fuel cycle. This is exactly the milestone for which the BN-800 was originally designed, a unique nuclear power unit supported by automated fuel production at the Mining and Chemical Combine. Advanced technologies for recycling nuclear materials will significantly expand the raw material base of nuclear energy by processing irradiated fuel instead of storing it, and it will also reduce the amount of waste generated.”  

Industrial fabrication of mox fuel began at the end of 2018 at the MCC. To create this unique production, broad industry cooperation was organised under the coordination and scientific leadership of TVEL, which also acts as the supplier of mox FAs for the Beloyarsk NPP. Initially, during the start-up of the BN-800 reactor, a hybrid core was installed, partly equipped with uranium fuel produced by Mashinostroitelny Zavod in Elektrostal (Moscow Region), and partly with experimental mox fuel assemblies manufactured at the Research Institute of Atomic Reactors in Dimitrovgrad, Ulyanovsk region.
