Tesla AC Not Cooling Air (Quick & Proven Fixes)

Are you facing trouble with your Tesla’s air conditioning? What should you do if your Tesla A/C was cooling before it stopped and now it is not working? What should you determine about your Tesla vehicle A/C not cooling inside your car?

To make things simpler for you and to identify the solution, in this article, I will provide you with the reasons for your Tesla A/C not cooling air and some tips to solve the problem before calling for a repair.  

Let’s Get Started…!!!

How To Fix Tesla A/C Not Cooling Air?

If you want to fix the Tesla A/C system not cooling air, you have to check the refrigerant levels and ensure that the other components (condenser, fans, and sensors) are in good working condition. Try to set up the Cabin Overheat protection & climate keeper feature, otherwise do a full power down or restart your Tesla vehicle.

1. Set up Cabin Overheat Protection (COP)

If your Tesla A/C is not working accurately then it may be due to improper functioning of COP. COP is part of your Tesla A/C system. It works to keep the interior of your Tesla vehicle cool for hours. 

Solution

To fix the issue you have to Re-Enable the COP correctly by following the below-stated steps:

  • Click “Controls” on your display screen.
  • Go to the “Cabin Overheat Protection” option.
  • You can see three options (Off, No A/C, On).
  • If the No A/C option is on then in that case the A/C cooling air will not work. Select Off and reset your Tesla vehicle.
  • To turn on you have to go to Controls > Safety > Cabin Overheat Protection.
  • After that, examine whether the A/C is working properly or not.

2. Soft Reset

Performing a soft reset will reboot your Tesla A/C system and fix any software errors or bugs that causing the malfunction of the A/C. But it will not fix any physical issues. 

Solution

By following the simple steps you can do a soft reset:

  • Turn off the A/C of your vehicle. 
  • Turn off the COP.
  • After that, hold down the scroll buttons for 15 seconds.
  • Wait until the screen turns black.
  • Go to Controls > Safety > Power off.
  • Wait for at least 3 minutes after the screen turns black.
  • Touch the display screen to activate your vehicle.
  • After that check the functioning of A/C.

3. Sensor Issue

To gauge the temperature of the air that is entering the evaporative coil there is a thermostat sensor or Air Temperature Sensor. If the sensor is not in its place your air conditioner system may operate randomly or cycle continuously. 

Solution

To avoid the problem you have to adjust the sensor’s position by carefully bending the wire that holds it in place so that it is close to the coil but without touching it. 

If your sensors face any damage you should replace them with new ones by following the below-mentioned steps:

  • First, you have to detach the hood.
  • By using a plastic pry bar you can remove the storage container under the hood.
  • To measure the humidity and temperature you have to find the sensor.
  • Disconnect the wiring harness connector.
  • Place the new temperature sensor in place.
  • Connect the wiring harness to the connector.
  • Change the storage container. You have to zip up the hood.
  • Recheck the functionality of your Tesla A/C.

4. Refrigerant Issue

The liquid that circulates throughout your air conditioning system and in return expands to provide your vehicle with cooling air is termed Refrigerant or sometimes often called “coolant”

If you lack refrigerant your air conditioning system will not be able to function properly and won’t produce cool air. 

If there is a leak your air conditioner’s refrigerant levels will eventually drop. If the condenser in your air conditioning system faces deterioration, cracking, or breakage due to normal wear and strain, it will affect the other components of your vehicle A/C. Any damage to your AC system’s tubes could result in a refrigerant leak.

Solution

It can be very challenging for you to locate a refrigerant leak. You should repair your vehicle’s air conditioning system every two years

Especially if you are living in a hot environment you need to maintain your Tesla vehicle air conditioning system. 

You have to examine every tube, searching for a colored mark (usually green), as this will show you where the leak is. 

To change the refrigerant you should follow the below-stated steps:

  • First, detach the hood.
  • Remove the top panel storage by using your bare hands.
  • Remove the air filter and vent.
  • From the storage area, you have to remove the rag.
  • Remove the storage’s four bolts.
  • Remove the entire panel.
  • Take out the charging port for low pressure being stuck to the larger aluminum hose.
  • When you turned on your Tesla vehicle it would start running at normal operating temperature.
  • Now you have to turn on the air conditioning system, and then select the coolest setting, and the maximum blower setting.
  • Check the hood for the AC compressor.
  • Connect the low-pressure charging port to the refrigerator.
  • Know to disconnect the refrigerant line from the low-pressure charging port.
  • Install a digital gauge.
  • Your refrigerant should be connected to the low-pressure charging port.
  • Spray your refrigerant to ensure adequate charging and for pressure reading check the digital gauge. After reaching the green range, it is finished.
  • Turn off your Tesla engine after removing the refrigerant line.
  • The wider aluminum hose is where the low-pressure charging port should be changed and inserted.
  • To put everything back you have to follow the reversed instructions.

5. Condenser Issue

The condenser is a crucial component of your Tesla air conditioning system. The condenser helps to compress the refrigerant of your air conditioning system, to chill the refrigerant. 

It is very prone to obstruction due to its placement. It can be susceptible to blockage from the outside material.

If your condenser clogs with debris it cannot function properly. In this way, your condenser is not able to transfer heat ultimately the refrigerant cannot be cooled. 

Solution

To avoid and to fix this problem you should inspect the air conditioning system routinely in your Tesla vehicle. If you find any debris clear it immediately

Also, clean the coils on the condenser. Your condenser coils are the crucial parts through which the cool outside air passes.

The other fix is that you can change your A/C condenser. If you hear a nasty wind noise after starting your vehicle and your vehicle A/C is not cooling air you have to replace your AC compressor. For that see this 

6. Damaged Fans

The Radiator fans in your Tesla vehicle are crucial for keeping the refrigerant cool. Even if your vehicle is idling, the condenser fan keeps the refrigerant cool. 

If the fan in your condenser is faulty or not working properly the air that your A/C system blows into the car won’t be cool. 

This is because of a loose connection, or the fan could have migrated slightly and is no longer in the best position for it to function, or because of any damage. 

Solution

It’s very simple to fix the loose connection problem. You just need to uninstall the connection and clean it properly then install it again tightly. 

Or you have to replace the condenser fan if you see any damage. Replace the condenser fan is a little bit complicated, however, if you have the experience you can easily replace the fan by adopting the following steps:

  • Turn off your vehicle.
  • Carefully examine the position of the fan (usually located in front or rear of your vehicle).
  • Disconnect the battery and other wiring connections.
  • Remove the old fan.
  • Place the new A/C fan in place using suitable connectors.
  • Reconnect all the disconnected wiring as well as the battery.
  • Turn on your vehicle and check that your A/C system functioning normally or not.
  • Re-check all the connections carefully.

7. Allow Additional Time to Avoid Sunlight and Summer Heat

Air Conditioning needs some time to cool down the atmosphere of the cabin. You should give some time to your A/C system to adjust and get used to the sun’s heat.

8. Need a Full Power Down And Restart 

After trying every troubleshooting method if your A/C still not cooling air then in such a situation, you have to go through Full Power Down and Restart of your Tesla. 

Solution

Follow some actions listed below:

  • Turn off the A/C option by selecting the Fan logo on the touchscreen.
  • Disable the Cabin Overheat Protection.
  • For at least 10 seconds you have to hold the steering wheel’s two scroll buttons.
  • Observe until the screen turns black.
  • Continue this for another 25 to 30 seconds. You can see your screen instantly.
  • Verify that your screen is ok before touching it.
  • Select the Power Off option under Controls > Safety.
  • Wait for it to come out for a maximum of three minutes after the screen goes black.
  • Press the brake pedal or the touchscreen to wake up your vehicle.
  • Check whether it functions properly or not.
  • If not, you must shut down your Tesla vehicle for another four to five times. The issue will be fixed.

Note: You have to disable the Bluetooth if your phone is connected to the Tesla for safety.

9. Check the A/C screen if the notification “Climate keeper inaccessible due to system failure” has vanished 

To maintain the inside temperature at 35% at a humidity level there is a feature in your Tesla vehicle that is termed as Climate Keeper. 

You can activate it manually by pressing the A/C button, or you can switch it on when the temperature in your Tesla exceeds 72 degrees. If you do not want to start it, you can disable the climate keeper.

10. Contact Tesla Customer Service Center

If using all the above-mentioned methods you are still not able to fix your problem then the best choice for you is to contact the Tesla customer service center. They will provide you with the best possible solution for your problem.

How you can operate your Tesla vehicle A/C system?

You should know about the operational mechanism of your Tesla vehicle A/C system to fix any problem related to air conditioning. Your Tesla automobile A/C system contains the below-stated components:

  1. Blowers
  2. Refrigerant
  3. Compressor
  4. Condenser
  5. Evaporator
  6. Orifice Tubes

For better results, you must use R-22 refrigerant for your vehicles as compared to Freon refrigerants. The reason is that they are less harmful to your environment and can also reduce greenhouse gas emissions. 

For the proper operational mechanism to work your vehicles require refrigerants that have to travel through the compressor. The condenser contains several coils.

How to prevent yourself from the problem in the future?

If you find the problem in your Tesla A/C it might be frustrating for you. Especially when you turn it on and it does not provide you with cool air. 

This problem can also cause you other difficulties. You can follow the below steps to keep yourself away from such problems in the future:
