Now I am going to explain the causes and solution in detail. So keep reading to know how you can fix this problem.

01. Disable automated Climate Control

Automatic climate control is a feature that Tesla provides that keeps the temperature at the chosen level by automatically enabling the climate control system. This can be the reason of the problem. The owner doesn’t realize that they have enabled it by the slip of touch or someone else has done this.

Solution

Check your climate settings and disable the automatic climate control system if it is enabled.

  • Turning on your Tesla’s touchscreen display.
  • Tap on the “Controls” icon located at the bottom.
  • Look for the “Climate” option and tap on it.
  • Look for the “Auto” or “Automatic” button
  • Toggle it off.

02. Maintain Battery Heat Level

As an electric vehicle, we all know that Tesla uses batteries to drive and perform its functions. If you think batteries would never get that much heat that they would need cooling, you are wrong.

Tesla’s battery keeps its temperature at a certain level for the safety and security of the vehicle and user. Your car AC can also keep turning in to maintain the temperature of batteries.

Solution

In this situation, it is good to keep the AC turned on because your Tesla is trying to keep the batteries from overheating. If you still want to turn the AC off you need to stop the vehicle and wait for the batteries to cool down.

03. Disable Cabin Overheat Protection

Cabin overheat protection is a feature that Tesla provides to maintain the temperature at 105 degrees Fahrenheit. When the temperature crosses the limit the cabin overheat protection mode turns on the AC.

So when the temperature inside your Tesla will increase it will turn on the AC and will keep turning on until the temperature maintains.

Solution

Maintain the cabin temperature by keeping the Ac on. Or disable the cabin overheat protection mode.

To disable the cabin overheat protection mode follow these steps,

  • Tap the “Controls” icon on the bottom bar of the touchscreen.
  • Look for the “Climate” option and tap on it.
  • Scroll down and find the “Cabin Overheat Protection” option.
  • Tap on the “Cabin Overheat Protection” option to access the settings for this feature.
  • You should see a toggle switch or an option to enable or disable the feature.
  • Toggle the switch to the “Off” position or disable the feature.

Once the Cabin Overheat Protection mode is disabled, the system will no longer automatically activate to maintain a safe temperature inside the vehicle during hot conditions.

04. Perform a soft reset to Tesla

In the Tesla, all the features like turning on the ac or turning on the climate control system, etc. are controlled by the main control unit or touchscreen. Sometimes some glitches and bugs enter the car software with the new software updates. These glitches and bugs can cause the problems like ac to keep turning on.

Solution

Performing a soft reset can remove the bugs and glitches in the software.

Follow these steps to perform a soft reset; 

  • Ensure that you are seated in the driver’s seat and the vehicle is parked.
  • Press and hold the two scroll wheels buttons.
  • Hold the buttons until the touchscreen turns off and the Tesla logo appears.
  • Now release the buttons and wait for the touch screen to reboot.

05. Check the sensors

The automatic climate control system uses sensors to measure the temperature and activate the AC if required. The malfunctioning of these sensors can cause the Tesla AC issue.

Solution

Clean the sensor and make sure there is no accumulation of dust and debris on the sensors. If the sensors are still not functioning properly, you need some professional help. Contact Tesla customer support or visit the nearest car dealership. Professional will investigate your sensors and will fix them or replace them with new ones.

06. Recalibrate the sensors

Calibration errors in the sensors can also be the reason for problems like these.

Solution

Recalibration of the sensors can only the calibration error. So you need to recalibrate the sensors to make them work properly.

To recalibrate your climate control sensors follow these steps,

  • Ensure that your Tesla is parked.
  • Exit the vehicle and close all doors.
  • Wait for 2 minutes to allow the sensors to reset.
  • Re-enter the vehicle and turn it on.
  • Tap the “Controls” icon on the bottom bar.
  • Tap on the “Climate” option.
  • Look for the option related to sensor calibration.
  • Follow the on-screen instructions.
  • Allow the system to complete the procedure.

07. Check Proximity sensors

These are the sensors that detect your presence in Tesla and activate the climate control system and AC to maintain the temperature inside the car. The malfunctioning of these sensors can also cause the Tesla AC to keep turning on.

Solution

Clean the sensors and ensure that there is no accumulation of dust or debris on the sensors. Try to recalibrate the sensors and replace them with new ones if needed.

For this, you may need some professional help. For this contact the Tesla customer support or visit a professional car mechanic.

08. Check Key Fob Interference or Malfunction

A malfunctioning or interfered key fob signal can also trigger the AC system to turn on when you are away from the vehicle. This situation may occur if there are nearby electromagnetic interferences or if the key fob battery is low.

Solution

Replacing the key fob battery with a fresh one. If the problem persists, try parking your Tesla in a different location, away from the sources of electromagnetic interference.

09. Remove the third-party app or device from your Tesla

The connection of third-party devices or apps in your main control unit can also cause glitches to enter your Tesla software and cause problems like this.

Solution

Remove the third-party app from your Tesla touchscreen or disconnected the third-party device from the MCU, if connected.

10. Remove the glitches from your phone and app

You can control almost all the features of your car through the Tesla app. So glitches and bugs in the app can also create these type of problems. The app can get glitches through the smartphone.

Solution

When glitches enter the app, it stores in cache storage. When you run the app, the glitches also run with it and cause problems. Clearing the cache storage of the app can remove the glitches and bugs and fix the problem.

Restarting your phone can remove the glitches from the phone and the app. So restart your phone once.

Sometimes the app receives temporary errors that can be removed by logging and logging back in. Log out your account and wait for 5 to 10 seconds and then log back in.

Reinstalling the app can also fix the problem by removing the glitches and bugs. To reinstall the app follow the following steps.

  • Delete the app first.
  • Go to “Apple Store” or “Play Store”.
  • Search “Tesla” or “Tesla mobile app”.
  • Now download and install it.

11. Hard reset your Tesla

If all the other solutions don’t work, you should go for a hard reset. Remember that all the data and information will be erased after performing the hard reset. So you should only try it with none of the explained solution work.

Follow these steps to perform a hard reset;

  • Ensure that your Tesla is parked, and the vehicle is turned off.
  • Open the front trunk and locate the 12V battery.
  • Disconnect the Negative Terminal from the battery.
  • Leave the negative terminal disconnected for at least 5 to 10 minutes.
