No air coming from vents

Air conditioner working but no air coming from vents.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Try to put the blower on high speed and move the mode to floor or windshield to see if any air is felt or the noise from the motor is heard. If you hear the blower running but still get no air anywhere, then check the blower motor for blockage in the blower fan. If you do not hear the blower working at all, then the problems are with the blower motor or the blower resistor in the blower housing. If you want to have this looked at by an expert, a certified technician, such as one from YourMechanic, can come to your car’s location to diagnose the AC issue and determine what needs to be repaired.

Here are some of the most common causes of why air doesn`t flow out of your vehicle`s vents: Your air intake is clogged, meaning that air isn`t getting in from the outside at all or isn`t circulating properly. There is a blown fuse in the ventilation system. Electrical issues such as a bad relay.
The most common reasons a Ford Fusion ac isn`t working are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor. You may not realize there`s a refrigerant leak until the air conditioner stops blowing cold.
Problems like a fan clogged with dirt, a dead motor, a loose fan belt or a stuck wheel can all cause your blower to not work properly. These problems can keep the blower fan from blowing enough air out of your vents to keep you cool. Your evaporator coil needs air to blow over it to complete your AC`s cooling process.
If your air handler is running but not blowing air, there are two likely scenarios; either a broken AC blower belt or an issue with the motor itself. If the air handler is humming or buzzing, but not making the mechanical sounds of a motor running, you`re most likely talking about an issue with the motor itself.
Vents Blockage

If you feel no air is blowing from vents in your house, vent blockage is most likely to be the issue. You might be blocking your air vents unknowingly; a piece of furniture might be in front and blocking the airflow, or you might have closed some vents on a chilly day and forgotten to open them again.

The most common problems that cause a lack of airflow include frozen coils, broken fan and restricted airflow due to dirty air filters or vent obstruction. However, there are many other issues that can lead to minimal airflow, so it may be necessary to ask the professionals.
You can reset the climate control for Your 2014 Ford Fusion vehicle by pressing the off and floor buttons at the same time, then releasing them. Now go ahead and press the auto button to reset the climate control and it should take a few moments to complete the reset.
It is usually located inside the blower compartment on the side of the blower motor. Be cautious as the housing may be hot. If the button is popped up, press it down.
Many vehicles have two fuses for the blower motor, one in the interior fuse block and the other under the hood. The blower motor is usually under the dashboard on the passenger side.
1) A Bad Fuse

The most common reason why your blower motor won`t work on any speed is that you have a bad or blown a fuse. A fuse is a small wire inside of a connector that is used to protect the motor itself from a surge of electricity.

Start by using a screwdriver to remove the vent cover. Then, use a flashlight to look inside the duct. If the blockage is near the vent cover, you may be able to see it and remove it. This is often as simple as just reaching inside to pull out a toy dropped in the vent or a dust clump that has built up over time.
An easy indication that your air ducts are dirty or clogged is when the system turns on, you may see a cloud of dust coming out the air vents. You can double-check this by turning off the HVAC system and waiting a few minutes after it has shut down. Turn it back on and see if dust clouds come out the vents.

Cold mist/smoke like air comes out of the air vents when cold air is on.
ANSWER : If you are using regular outside air a/c instead of recirculated air you may be getting a large amount of outside air humidity and can cause a mist to come out of the a/c vents. You should make sure the a/c evaporator drain is cleared and drains freely or the water in the a/c cannot drain fast enough and the blower will pick up the water and blow it out the vents.

Air does not come out of the vents very well or at all most of the time. Air does come out of the defrost though.
ANSWER : Hello there, a few different things can cause the air to only blow out of the defrost vents. The car’s HVAC system uses a few doors, such as the blend and mode doors to direct the air through the dash and determine where it comes out and what temperature it is. Given that the air works out of the defrost, the most likely cause would be the mode selection vent. A qualified technician, such as one from YourMechanic, will be able to diagnose your AC issue and perform any repairs required.

My heater is blowing air through the driver side air vents but is blowing cold air through the passenger side and rear console ven
ANSWER : Hi there:

Climate controlled vehicles have multiple electrical relays that open and close vents to maintain the desired temperature. In some instances, these relays can wear out overtime. However, it’s also common for debris to clog up vents (especially side vents) which may restrict the flow of cool air. The best way to determine why your AC is not working efficiently, it might be best to have a professional mechanic complete a AC inspection; so they can pinpoint the source of your issues and recommend the right repairs.

Problem with AC/heater – 2005 Ford Explorer
ANSWER : Hello. The problems you describe with the front system may either be a faulty control switch or faulty vacuum motors for the air blend doors. The problem in the rear is likely the rear heater control valve, which regulates the flow of hot coolant to the rear heater core and air duct system. The clicking noise may be a broken vacuum motor for that valve (integrated in the valve).

I would recommend having a certified mechanic, such as one from YourMechanic, come to your location to perform an inspection of the heater and suggest the needed repairs.

Hot air mixed with cold blows from air conditioning
ANSWER : Hey there. You will most likely have to have a mechanic bypass the heater coolant lines to have this resolved. Your A/C may not be controlling the air flow inside the evaporator correctly out of the vents and may be the blend door actuator stuck in the heat position. Have the AC system diagnosed first before bypassing the heater.

I have exhaust coming into the cabin via the air vents, and much more when the vehicle is stopped. Air filter or leak somewhere?
ANSWER : The air filter is not a cause of the problem you are describing. Nevertheless, if the air filter has not been serviced as required be sure to change it as that filter is important. Sometimes wind conditions, not to mention other traffic, can be the source of exhaust odors in the cabin. However, if you suspect that the origin may be your own vehicle, due to a leak, please request an exhaust system inspection – suspected leak and the responding certified mechanic will get your concerns addressed. If you have further questions, do not hesitate to re-contact YourMechanic as we are always here to help you.

No air coming through any of the vents, defrost, etc.
ANSWER : It sounds like you may have got something stuck in the blower for the A/C. The blower may be blocked or may have burned up. Have the blower removed and tested and checked for a problem. You may have something caught in the motor causing it to lock up. I have seen paper, pens, and even rodents. I know it sounds weird but it happens. It can also just be a blower resistor and blower motor. To have the fault pinpointed in person, a certified mechanic from YourMechanic can take a look at your car to diagnose your AC issue and squealing sound that you are hearing.
