Changing the fuse can solve the problem, or it can simply be a blown a fuse. There is no difficulty in replacing it. If it works intermittently, there may be a problem with your air/heat. When the blower motor operates in one mode and does not in another mode, then you may need to replace the blower motor resistor.
The most common reasons a Honda Accord 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.
With the fan on, push the A/C button to operate the air conditioning. The indicator light will come on. Push the button again to turn off the air conditioning. When the button is pushed, the indicator light will go on and outside air will be circulated inside the car.
The blower motor is responsible for sending air through the vents of your car. Over time, blower motors can become damaged, or completely fail. In which case, air will no longer come out of your vents.
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.
If your car`s air conditioning isn`t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system.
Nine times out of 10, weak airflow is caused by a clogged up cabin air filter. Over time, this filter catches all dirt and debris, which can build up and slow or stop the flow of air. It`s typically located under the dash on the passenger side or inside the glove box and should be cleaned or replaced regularly.
The air-conditioning system in a car works by manipulating refrigerant between a liquid and a gaseous state. As the refrigerant changes states, it absorbs heat and humidity from the vehicle and allows the system to give off cool, dry air.
Cool Mode. Commonly symboled with a snowflake – the cool mode is basically the default mode of most AC units. When you use this mode, your air conditioner starts by turning on the compressor to push cold air into the room.
However, when the car is moving, this might not look like an issue as the outside air will go through the engine. But when the car is not moving, there is no air from outside to cool the engine; therefore, the AC doesn`t work when the car is not moving.
You cannot run the AC without the engine running. The air conditioner compressor and clutch are operated by the serpentine belt that runs your other accessories (your alternator, for instance). If the engine isn`t running, then the belt isn`t turning. That means your air conditioner`s not actually on.
Fresh, unpolluted air enters your home through the intake vents placed at the low points of your roof. Air expands and rises as it becomes warmer, so the hot, moisture-filled air rises and escapes through the exhaust vents placed at the height of the roof.
The HVAC system will fill the supply plenum with heated or cooled air, which then is sent through the ductwork of the system. When this heated or cooled air enters a room, it pushes the already-present air out of the room into another set of ducts. These ducts deliver this returned air to the return plenum.
If you are looking at a duct that is coming off the furnace and going straight up like it is going to the upstairs, and the wing is in the same direction as the duct, it is open. If the wing is in the opposite or vertical position to the ductwork, then the damper is closed.
A runny nose and sneezing can happen too. If poor ventilation continues to be a problem, you might experience headaches, fatigue, and shortness of breath. Dizziness is a common symptom too. All of these symptoms are magnified in sensitive groups who have respiratory diseases or asthma.
A second reason for the air conditioning unit to suddenly prefer blowing warm air may be because the compressor itself has gone bad. The main function of the compressor is to pressurize the contents in the refrigerant, and then pump it throughout the necessary components of the AC.
The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.
If you are experiencing weak airflow from vents in the house, check whether it is happening only in one vent or multiple vents. In case only one vent shows the problem, you may be having a problem with a disconnected or leaky duct, a crushed duct flex or a closed damper.
If the heater isn`t blowing hot air at you when you turn the system on, the blower fan might have a problem. Either it`s not getting electrical power or, more likely, the motor itself has simply burned out. A blower motor in an older vehicle is likely to burn out over time, and may need replacement.
A fan clogged by dirt, a stuck wheel, broken motor, or a loose fan belt are all common problems that reduce the amount of airflow you feel coming from your vents.

Blocked Vent or Duct A reasonably simple explanation for poor airflow in a particular area of your house could be that you have a blockage in an air duct near that area. If the problem affects one room, the vent in that room could have some blockage.
