my car ac is running but not blowing air?

If you do not feel any air or if you only feel air coming through the vents on certain settings, the problem may lie with the AC's blower motor or the blower motor resistor. Sometimes blower motors and/or their resistors will fail and stop pushing both hot and cold air through the vents.

Low refrigerant If your car's refrigerant is low, it can keep your air conditioner from functioning properly. The compressor won't cycle if the amount of pressure in the system is low. In most cases, this is the cause for the lack of cold air.

If the air handler is working fine, the fan will still blow air into your space. But without the condenser unit working properly, there will be no cooling; hence, your AC blowing warm air.

One reason for an RV air conditioner not blowing cold is clogged condenser fins and external leaks. Dirt, leaves, and spiderwebs can collect in the condenser coils, so first make sure the fins are clean. Also, you can use the foil tape to seal the blower box from the outside.

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.

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.

Car AC blows cold then warm. If your car AC blows cold then warm, the cause can be a low system charge, moisture in the system, a malfunctioning expansion valve, clogged evaporator fins or an overcharge condition. Here's how to nail down the cause.

How Does The Air Conditioning In My Car Work? A vehicle's air conditioning system does not create cold air. ... The a/c compressor initiates the high-side of the system where it is compresses the freon/refrigerant into a high-pressure state causing it to liquefy. It travels through the high-pressure lines to the condenser.

So what caused your air conditioner to stop working? Most likely, your AC system lost its charge of refrigerant. Or, due to an electrical fault, its compressor is not engaging when you turn on the system. Another possibility is that an internal obstruction is blocking the circulation of refrigerant.

It is most likely an electrical problem with your AC. Capacitors are like mini jump starts for the various motors in your AC system. ... Each motor has its own capacitor and if one of them is not working, then it usually means that the motor won't run. This can effect the compressor and not the fan.

Fan and Fan Motor If your window air conditioner is not blowing any air, the problem could be the fan or fan motor. ... If the circulating fan is not running or running too slow, little or no air flow over the evaporator coils will allow them to become too cold and frost or ice can form, restricting the air flow even more.

You will be fine as long as you don't need or want AC in your car. ... If the clutch doesn't work properly, you will still be able to drive your car. I have seen it so many times on vehicles where they just don't use their AC; however, if your AC compressor doesn't work, you won't have cold air coming from your vents.

When your system's air filter is full of dirt and debris, the flow of air is restricted, which can impede the functioning of your air conditioner. Without enough air flowing over the coils, the system can't remove humidity and cool the air to the set temperature, so it keeps running when it shouldn't.

Low Refrigerant: Low refrigerant will prevent your air conditioner from operating (the clutch won't kick in and make the compressor cycle if the amount of pressure in the system is off). This is actually the single most common problem for an AC not to blow cold. ... The same is true for your car's AC system.

Poor Air Flow If you are noticing weak or little airflow through your AC vents, the unit's compressor may be failing. In case certain areas or rooms in your home are getting cold air while others are not, then the trouble might be with your ductwork and it's a sign that your AC system needs urgent repair.

If your car AC blows cold air when driving at highway speeds but turns warm at stop lights or when driving at slow speeds, you may have a bad radiator fan or radiator fan relay.
