When the air conditioner in your vehicle isn’t blowing cold enough, the problem is often caused by a dead battery. Recharging your air conditioner’s refrigerant is something you can do on your own. However, it’s possible that if there’s a leak in the system, it may create a lot of trouble. To function, modern air conditioners need a certain quantity of freon, and this makes them potentially fragile appliances.
Repairing your car’s air conditioning might include anything as easy as topping up the refrigerant or fixing a leak. However, it could also need more involvement, like replacing the sliding compressor clutch or repairing the electrical temperature control system. This article will give you more details on how to fix car ac not blowing cold air.
How To Diagnose Your Car’s AC Problems
Those who endure scorching summers know the frustration of a broken air conditioner. There are occasions when air conditioning won’t work, but more often than not, it gradually loses power until you turn it up to full blast and find that you’re still sweating. Your car’s air conditioner may produce warm air for various reasons, some of which are simple to repair.
If you know what to look for and have a basic understanding of the AC system’s parts, you should be able to fix any problems that arise. Check out some fundamental issues and how to fix car ac not blowing cold air.
- LOW REFRIGERANT
Refrigerant is pumped via metal tubes in air conditioners and refrigerators to cool the interior. When exposed to room temperature, the refrigerant boils and transforms into a gas, collecting heat from the air in the same way as rubbing alcohol evaporates off the skin. The atmosphere is pushed into the cabin by the fans.
The refrigerant charge in air conditioners gradually decreases over time. It might occur naturally in an open system or because of a leak. If the refrigerant level is low, a simple solution is to add more; you can do this at any NAPA Auto Parts shop. Unfortunately, if there is a leak in your system, you will need to track and fix it. It is more challenging and requires specialised equipment like dye and leak detectors.
Refrigerant is hazardous to human health and the environment; thus, you must always exercise care while recharging or fixing your air conditioning system.
- CONDENSER ISSUES
The condenser for your car’s air conditioner is the coil system that makes it seem like a little radiator. There are two types of problems mainly faced due to condenser issues:
- Blocked Condenser
When the heated refrigerant is compressed, it is re-cooled by the condenser in your air conditioner. It is achieved by directing air from the front of the vehicle. Road debris that has gotten up on the condenser might prevent it from functioning correctly. If this happens, your air conditioner may stop working efficiently and may even begin to produce heated air. See if there is a grill blockage since this might cause the problem. Taking it out will return your AC to regular operation if there is.
- Broken Condenser
If the condenser is checked and nothing obstructs it, yet it still doesn’t operate, it may be damaged. For example, it may have been pierced by a piece of road debris, or the equipment might have broken. You need to have a professional replace your condenser if you want to remedy this problem.
- COMPRESSOR ISSUES
The compressor of your air conditioner functions as a pump to maintain constant refrigerant circulation. Your air conditioning will stop working without it. Locate the compressor under the hood (it is powered by the serpentine belt and other components at the front of the engine) and listen for the clutch to “click” on and off when the vehicle is in motion. It might be broken or not getting electricity if it doesn’t turn on. On the other hand, a lack of refrigerant might cause its quick cycling on and off.
- BLEND DOOR
While broken blend door actuators won’t keep you from getting where you’re going, they might make the ride less pleasant.
The actuator is the conduit via which signals are sent when you adjust your air conditioner’s settings, such as the temperature and the airflow. The actuator will then change the position of the mix door to match. For example, a mix door actuator may be reset by removing the actuator and setting the thermostat to its highest heat setting. Next, turn the blend door shaft until the vents produce the most heat possible, and replace the actuator. After that, activate the a/c and check the blend door actuators before reassembling.
- Freon Leak
The chemical refrigerant known as Freon is responsible for cooling the heated air down before it is recirculated back into your vehicle. A significant problem may arise if there is a leak in the system. Modern air conditioning units may be somewhat fragile and need a certain level of freon to function correctly.
The leak source might be a broken hose, a faulty gasket, or even a connection that has become loose. So, first, we need to locate the leaking components, then we can either repair them or replace them, and last, we may recharge the system with Freon.
- Bad Fans
If your fans stop working, your condenser won’t get the cold air it needs to function. Because of this, your car’s air conditioner will stop working. The simplest method to tell whether your cooling fan is on the fritz is to have a look at it. Bringing your Toyota in for servicing at Toyota of Santa Clarita if you notice the fan is not working correctly or has stopped working is a good idea.
- Bad Compressor
The central part of your car’s air conditioner is the compressor. You won’t have any cool air blowing through when the system fails. The most typical cause of compressor failure is shock, which occurs when the machine is switched on after being idle for an extended period. Avoid this by letting it run once every several weeks throughout the winter. A professional should be called in to repair a faulty compressor.
Car Ac Not Cooling In Hot Weather.
A broken vehicle AC can spoil your day quickly. Leaks or compressor problems cause most AC breakdowns. If your air is chilly but not frigid, you may have a clogged filter, fan or radiator issue, or you may need to recharge your AC. You don’t have to put up with a stuffy, uncomfortable automobile, nor does the store. Warm air may have several sources. Here are the steps to know how to fix car ac not blowing cold air
- Refrigerant leak
A refrigerant leak causes an automobile A/C to blast hot air. Refrigerant expands and contracts as it eliminates heat and humidity from your car’s interior. Without enough refrigerant, other A/C components won’t work. For example, old hoses and rusty or pierced evaporators might leak. Unfortunately, a refrigerant leak isn’t always apparent.
A puddle in or beneath your automobile may go unnoticed. Antifreeze evaporates, unlike motor oil and other automotive fluids. Sometimes an oily deposit marks the leak. Our experts inject dye into the system to find refrigerant leaks. Once they find the leak, they fix and recharge your A/C so it can blow cold air again.
- Faulty condenser
The refrigerant absorbs heat and humidity as your A/C pushes them out. The condenser keeps the refrigerant cold so that the cycle may continue. When you’re hit by hot air. The condenser is between the grate and the radiator. It cools using grate-flow air. If road debris blocks the condenser, air can’t reach it, preventing the refrigerant from cooling. Looking through the grate may reveal a malfunctioning condenser. If your automobile A/C troubles began after a fender crash or bumper hit, your condenser might have broken.
- Broken compressor
The compressor is an A/C heart that circulates the refrigerant. The antifreeze won’t cool the condenser if this item doesn’t operate. Long winters without A/C might cause compressor troubles. Newer cars keep the condenser operating year-round by using the defrost setting.
- Problems with the electrical system
If your car’s A/C is operating, it may have an electrical problem. Frayed wires or blown fuses might disable a healthy A/C. Inspecting your car’s fuse box and wiring helps diagnose and fix electrical issues.
Car Ac Compressor Running But Not Cooling.
If the air conditioner does not provide enough cooling, this may be one of the general difficulties. But, again, you can provide your diagnosis. Open a holder in the dashboard, and if the cabin filter is filthy, removing it will reveal the reason why it is restricting the amount of air that is allowed to enter the cabin correctly. If such is the case, it is time to alter it.
It is something you can do on your own; all you need to do is go out and get a new authentic Cabin Filter and put the old one in its place. If you still have the same problem, you should make an appointment at the authorised workshop as soon as possible.
Frequently Asked Questions
Why is my AC running but not blowing cold air?
The necessity for the air conditioner in a car to be recharged is the most frequent reason why it does not produce a sufficient amount of chilly air. Of course, you can restore your refrigerant by yourself; however, if you want to save time and ensure that the task is done correctly, you should schedule an appointment with your neighbourhood auto shop, which trained professional staff.
How do I make my car AC cold again?
Follow the steps to make your car AC cold again:
- Put in a new filter for the car’s interior air
- It’s best to park in the shade if you can.
- Power up your air conditioner
- Don’t turn on complete air conditioning immediately or soon
Why is my car blowing out hot air when the AC is on?
When the air conditioning in a vehicle leaks refrigerant, the typical outcome is hot air being blown out. The refrigerant in your vehicle’s air conditioning system is a liquid that flows through the system in a cycle of expansion and contraction as it eliminates heat and humidity from the cabin. Without the right amount of refrigerant, none of the other components of the air conditioner will operate appropriately.
