It’s a joy to have air conditioning, especially when it’s sweltering outside. Do you still perspire while using your Corolla? Your air conditioner unit no longer provides adequate cooling? There may be several reasons for this. In this post, we describe what these are and what you may do to address them.
The most frequent reasons why your Toyota Corolla’s air conditioning system fails to function normally include a dirty cabin air filter, a refrigerant leak, a dirty or clogged condenser, a dirty or clogged evaporator, a bad blower motor, a faulty compressor, a faulty blend door actuator, or any electrical system issue.

Why isn’t the AC working in my Toyota Corolla?
Refrigerant leaks, electrical climate control problems, or issues with the air conditioning compressor are the three most frequent causes of air conditioning problems in Toyota Corollas. Before the air conditioner quits blowing cold, you might not be aware that there is a refrigerant leak.
How much does a Toyota Corolla’s AC repair cost?
A Toyota Corolla car AC repair typically costs $249, which includes $116 for components and $133 for labor. Prices may change based on where you are.
How much does a Toyota AC repair cost?
Typically, the cost to repair a car’s air conditioner ranges from $100 to $900, depending on the severity of the problem. When you need to buy extra components like a new compressor, condenser, sensor, or hose, costs are likely to increase.
Why does my car’s air conditioner operate but not cool?
Leaks or compressor problems are the two most frequent reasons for faulty air conditioning. If your air conditioner is blowing chilly air but not frigid air, the issue may be a clogged filter, cooling fan or radiator malfunction, or it may just be that your AC needs to be recharged.
The AC in my Toyota Corolla won’t turn on.
Although I’m delighted you can still get around, I’m sad to hear you have to cope with this while your car is being repaired.
In a Toyota Corolla LE, simply follow these easy steps to switch on the air conditioning:
- Start the car’s engine.
- Just below the radio controls is where you’ll find the climate control settings. You ought to see three large knobs.
- To adjust the fan speed, which ranges from zero to four, turn the central knob. By firmly pressing the middle of this knob, you can also activate the rear defogger.
- From chilly to hot, adjust the temperature with the knob on the right side. To start the AC, press the middle button.
- To adjust the airflow direction and activate the recirculation feature, use the left side knob.

How much does fixing the AC in a CAT cost?
For an AC repair, you should budget between $10 and $1,000. If all you need to do is replenish the refrigerant and you can do it yourself, you may pay as little as $10. However, you can easily spend $1,000 or more if parts need to be replaced or you need a qualified mechanic to work on them.
The possible fixes for the AC system are listed in further detail below.
AC System Leak
The system can simply be low on refrigerant. This is the most affordable and straightforward issue to fix. You may purchase a can of Freon for $10 or less if you have the gauges and knowledge necessary to replenish the system (Even if we strongly recommend a professional mechanic with the right tools to fill it to avoid issues).
However, if the refrigerant level remains low, a leak can be present. Refrigerant shouldn’t be able to leak more than 1 ounce per year in a closed system. It’s conceivable for the hoses and clamps to wear out and break as they age.
To locate the source of the leak, apply a specific UV dye. With the help of the provided special glasses, you check for leaks while the dye is poured into the system.
Any leaks you uncover must be fixed before you may recharge the system. You are looking at spending very little money if the leak is at an O-ring. On the other hand, repairing some parts will set you back $500 or more. In either case, you don’t want to allow a leak to continue because it harms the environment and could harm the compressor.
Clogged Cabin Filter
Even if you might not link the cabin air filter to the car’s temperature, evaluation is crucial. The filter can be clogged if the air is warming up. The proper amount of airflow through the system won’t be possible if the filter is clogged. By periodically replacing the filter, you can avoid a clogged one. A replacement is advised every 15,000 to 30,000 miles by the majority of manufacturers.
Once more, this repair is inexpensive and practically tool-free, and it can be completed in your garage. Costs for a replacement cabin filter range from $10 to $25. You should be able to remove the clogged filter and replace it in a matter of minutes. You might have to pay for labor for an hour if you can’t do it yourself.
Why does a car’s air conditioning cease working?
The most frequent causes could be a blocked filter, a problem with the cooling fan or radiator, or you might only need to recharge (regas) your air conditioner.
How can I tell if the compressor in my car is damaged?
When you turn on the air conditioning in your car, you might hear some odd noises; if so, the compressor is most likely the source. When triggered, this component may grind or whine once it starts to malfunction. These noises are the result of internal parts malfunctioning, such as the bearings. Check to see if the noise ceases by turning off and back on your air conditioning. If so, you have an AC issue.
How can I identify a faulty AC compressor?
Your home may not keep as cool as it once did, or the air coming from the vents may not be cool at all.
Another indicator is diminished airflow. Compressors can’t produce as much cold air while they’re having trouble.
When your outside unit turns on, if it seems to start slowly or rattles and trembles, the compressor might be failing. It’s a given that your AC need repair.
Your AC’s circuit breaker may be tripping often due to a faulty compressor. Breakers trip as a result of overloading or short circuits. Tripping frequently is a sign of a more serious problem.
When your air conditioner makes clicking, ticking, or rattling noises, something is wrong. Either your compressor has failed, or another issue exists. These noises should prompt you to schedule maintenance on your air conditioner.
Any area of your HVAC system where there are puddles or dampness could be a sign of a refrigerant leak. Systems will eventually stop working since there is no longer any refrigerant available to produce cool air.
Why doesn’t the AC produce chilly air?
The chemical that starts the entire process in action is the refrigerant, which is most frequently Puron or R410A.
The refrigerant may be the cause of your central air conditioner’s failure to produce chilly air. The system can be low on refrigerant and require more to be added.
A leak is the most likely culprit here. In addition to preventing the AC system from cooling correctly, a leak might result in other problems inside the house. For instance, if your home’s temperature isn’t cold enough, the humidity can increase and make it feel hotter inside than it actually is.
You should speak with an HVAC expert right away if you think there might be a refrigerant leak. It can be challenging to accurately diagnose and rectify these leaks, even if they are small.
How can I re-chill the air conditioning in my car?

The last thing you want when it’s as hot as a sauna outside is to get inside your car and have even more scorching air blasted in your face. If your car’s air conditioning isn’t cutting it this summer, find out how to make it colder so you can reserve that overheated sensation for a nice workout at the gym.
Replace the cabin air filter
Dust, pollen, dirt, and other pollutants are kept out of your car through the A/C and heat vents thanks to the cabin air filter. If the filter is clogged or unclean, it can also restrict or even completely block A/C airflow, making it difficult for the chilly air you long for to enter the cabin.
You might be able to check and replace the filter yourself depending on your car. For more details, consult your owner’s handbook.
Park in the shade whenever possible
By avoiding heat buildup inside your automobile, you can jumpstart your A/C. When the ambient temperature is 80100F, cars parked in direct sunshine can have interior temperatures of up to 131172F.
Don’t keep your windows partially open or cracked out of consideration for safety and security. Instead, park in a shaded place.
Create some shade if parking in it isn’t a possibility. Install a windshield sun shade to keep your car from becoming an oven due to intense sunshine. Sunshades can also aid in shielding the interior of your automobile from corrosive UV rays that lead to dashboard cracking and discolouration.
Supercharge your A/C system
Restarting your refrigerant will quickly make your car’s air conditioning colder. We won’t get into the specifics of how a car’s air conditioner operates, but suffice it to say that a lack of refrigerant or low Freon levels nearly always result in a car’s air conditioner that doesn’t seem chilly enough. If you have access to an A/C gauge and thermometer, two items that are offered at most auto parts stores, you may check your refrigerant level at home.
Don’t switch to max A/C right away
When you first get in the car, it may be tempting to switch on the A/C and set the temperature to “max cool.” But did you know? It’s not the best idea to turn on the air conditioning immediately away to make it cool. Your automobile actually pulls air from inside, cools it, and blows it back inside when your A/C is set to “max.”
The issue with that is that the air inside the automobile is hotter than the air outside when you first get in. (Remember how the interior of your car can reach about 200F?) Without good reason, you’re making your air conditioner work harder. Start by drawing air from the outside of the car to feel cooler more quickly. Turn off the A/C button initially. Make sure the airflow is set to “outside” mode and set the fan to its highest speed.
Turn on the A/C and select the “recirculate” airflow mode once you’ve expelled some of the hot, humid air that has accumulated within the car outside. The A/C can now be set to “max cool.”
Quick disconnect fitting for AC recharge charging port
Some recharge kits have this fitting that quickly and securely connects to the AC recharge charging connector.
Your air conditioner probably lost some refrigerant during the winter if it was blowing ice-cold air last year but is now hardly cooling. When aging seals shrink and some refrigerant leaks out, that occurs in older automobiles.
Typically, turning on the automobile air conditioning will send you back to the freezing cold. If your car was built after 1993 and is filled with R-134a refrigerant, you can complete that task by yourself (to make sure, check the label under the hood or the specifications section of your owner’s manual).
Restrictions may apply to the sale of R-134a refrigerant to consumers in several states. The cans may occasionally be designed differently, necessitating various charging techniques. All AC issues won’t be resolved by charging the AC. However, if you’re willing to risk $50 on a rechargeable ac kit, you could become a cool dude in less than an hour. By performing the auto ac recharge yourself, you can save roughly $100 on labor.
Pick up an R-134a A/C recharging kit at any auto parts store. Because it included a quick-connect fitting and reusable gauge, as well as a seal conditioner ingredient in the refrigerant, I used the A/C Pro product you see here. For an AC recharge for a car, however, any brand will work. A word of caution: Many commercial recharging kits utilize oils and seal conditioners that are incompatible with the electric AC recharge compressors in hybrid vehicles. A fatal electrical shock might be caused by using the incorrect auto ac recharge kit. Before making a purchase, verify that your hybrid vehicle is compatible with the car ac recharge product on the label. Consult a professional if you’re unsure.
Caution
If used incorrectly, refrigerant can result in frostbite and severe eye damage. Wear gloves and goggles when doing the process, and pay close attention to all the warnings in the package instructions.
