Causes of AC Problems in a Ford Vehicle
Clogged Cabin Filter
If the airflow from your AC is choppy, the cabin filter in the system might be clogged.
The role of your cabin filter is to remove dirt in the AC. This ensures that air moves smoothly through the system.
The purpose of your cabin filter is the very reason it gets clogged. As the cabin filter accumulates dirt, the debris fills its surface and blocks air from moving through it. Only the little air that squeezes through the clogged filter will pass through your vents.
If you aren’t getting enough air from your AC, clean your cabin air filter with a shop vac.
Bad Cabin Filter
If your Ford AC doesn’t blow air properly after you’ve cleaned the cabin filter, the filter might be broken. Sometimes, dirt sinks into the deep layers of the cabin filter.
Unfortunately, you can’t remove such debris by cleaning the filter.
The only way to fix this issue is to replace the cabin filter.
Bad blower motor
A broken cabin filter isn’t the only reason you may get choppy airflow from your vents. Your AC may also fail to blow air smoothly if your blower motor is bad.
The easiest way to tell if you have a bad blower motor is to listen for weird noises in the dashboard. If you keep hearing strange sounds from your dashboard, chances are your blower motor is damaged. As such, you’ll need to replace it.
Low Refrigerant Levels
Is your Ford AC blowing warm air? Then, the refrigerant in your AC might be low.
The refrigerant gas absorbs the heat in your AC’s interiors, so that the air in the AC can stay cool. If the gas in the AC is not sufficient, the heat will remain within the AC. This forces your AC to blow warm air.
Usually, refrigerant levels fall if you don’t service your AC for a long time. So, if you haven’t maintained your AC in a while, the system may not have enough refrigerant. In that case, you’ll need to recharge your AC.
Take your Ford car to the nearest shop and ask for an AC recharge.
Faulty Blend Door Actuator
If your AC vents keep releasing warm air, you may have a bad blend door actuator. Because there are several issues that cause the AC to blow warm air, it might be difficult to tell when your blend door actuator is faulty.
But there is an easy way to detect this issue: Turn the climate control switch to Full Cold. If the AC still blows warm air at Full Cold, your blend door actuator is faulty.
Resetting your blend door actuator should fix this issue.
Another reason your Ford AC may not function properly is a dirty evaporator. You can tell that your evaporator is dirty if the AC gives off a bad smell. Your AC may also blow warm air.
Remember how the refrigerant collects heat from the AC? Your evaporator is the component that transfers the heat from inside the AC to the refrigerant gas.
Sometimes, dirt escapes the cabin filter and spills into the evaporator. This debris will eventually build up and clog the gaps in your evaporator.
Without a functional evaporator, your AC interior will become stuffy. As a result, the system might emit an unpleasant odor. Since a dirty evaporator can’t absorb heat from your AC, the AC will blow warm air.
To resolve this problem, you’ll need to clean your evaporator.
A Dirty Condenser
A dirty condenser can cause your Ford AC to blow blazing hot air.
After your evaporator transfers heat to the refrigerant gas, the condenser collects the heat and deposits it outside the AC. If the condenser is too dirty, it won’t be able to do its job.
Since your clogged condenser can’t release heat from the refrigerant gas, your AC interiors will stay warm. This causes the AC to blow hot air instead of cool air.
Once you clean your condenser, your AC should resume blowing cold air.
A common cause of Ford AC problems is a bad compressor. When your compressor is broken, you may feel like the air from the AC isn’t cool enough. This is because the compressor is responsible for generating the moisture that converts the cool air in your AC into freezing air.
Consider replacing your compressor if your AC can’t blow cold air.
Other Ways to Troubleshoot AC Problems in Your Ford Vehicle
Clean Your Cabin Filter
If your Ford AC isn’t blowing air properly, you might need to clean your cabin filter.
Follow these steps to clean the cabin filter in your Ford car:
- Open the glove box on your passenger side.
