What happens when you want to warm up or cool down your car before you get in, and the app says “Failed to turn on climate”?
This is a common problem that many Tesla owners face, and it can be very frustrating and inconvenient.
In this article, we will explain what causes this error, how to troubleshoot it, and how to fix it.
How to Fix Tesla Climate On Failed Issue?
There are several possible reasons for this error, and some of them are easy to fix by the user. Here are some troubleshooting steps that can help resolve this issue:
#1. Wait and retry
Sometimes, the error can be caused by temporary server issues or background tasks on the car. Waiting for a few minutes and trying again can solve the problem.
#2. Check internet connectivity
Both the phone and the car need to have a good internet connection to communicate with the Tesla servers. If the phone or the car is in a low-signal area, the app may not be able to send or receive instructions.
Moving to a better location or switching between Wi-Fi and LTE can improve connectivity.
#3. Check battery level
The car needs to have at least a 20% battery charge to activate climate control remotely.
If the battery level is too low, the car may not respond to the app command. Charging the car or driving it for a while can increase the battery level.
#4. Restart the Tesla app
Sometimes, the app may have a glitch or a bug that prevents it from working properly.
Closing and reopening the app can refresh its functionality and clear any errors.
#5. Reboot the phone and/or the car
If restarting the app does not work, rebooting the phone and/or the car can also help. This can force a fresh connection between the devices and the servers and fix any software issues.
To reboot the phone, simply turn it off and on again. To reboot the car, press and hold both scroll buttons on the steering wheel until the touchscreen goes black, and then release them.
#6. Update the Tesla app and car software
Tesla regularly releases software updates for both the app and the car that can improve performance and fix bugs.
Making sure that both devices are running the latest version of the software can prevent or resolve many issues.
To update the app, check for updates on your phone’s app store. To update the car, connect it to Wi-Fi and check for updates on the touchscreen.
#7. Check the fuses and relays
The climate control system relies on fuses and relays to protect and control the electrical circuits.
If a fuse blows or a relay fails, the system may not function properly. You can check the fuses and relays in the fuse box under the hood or in the trunk.
Refer to the owner’s manual for the location and identification of each fuse and relay. If you find a blown fuse or a faulty relay, replace it with a new one of the same rating.
#8. Inspect the coolant level and pressure
The climate control system uses a coolant to transfer heat from the cabin to the outside.
The coolant level and pressure need to be within the specified range for the system to work efficiently. You can check the coolant level and pressure using a gauge or a tester.
The coolant reservoir is located in the front trunk, next to the windshield washer fluid reservoir.
If the coolant level is low, add more coolant until it reaches the full mark.
If the coolant pressure is too high or too low, there may be a leak or a blockage in the system. You may need to contact Tesla support for inspection and repair.
#9. Clean the condenser and evaporator
The condenser and evaporator are two components that exchange heat between the coolant and the air.
The condenser is located in front of the radiator, behind the front bumper. The evaporator is located inside the dashboard, behind the glove box.
Over time, dust, debris, and bugs can accumulate on these components, reducing their efficiency and airflow.
You can clean them by spraying water or compressed air through them. Be careful not to damage the fins or coils with too much pressure or force.
#10. Replace the cabin air filter if due
The cabin air filter is a device that filters out dust, pollen, and other contaminants from the air entering the cabin.
It is located behind the glove box, under the dashboard. A dirty or clogged cabin air filter can reduce airflow and affect the performance of the climate control system.
You should replace the cabin air filter every 12 months or 15,000 miles, whichever comes first. You can buy a new cabin air filter from Tesla or other online retailers To replace it, follow these steps:
1. Open the glove box and remove any items inside.
2. Press both sides of the glove box inward to release it from its hinges.
3. Pull out the glove box and disconnect any wires attached to it.
4. Locate the cabin air filter cover behind the glove box opening.
5. Remove the four screws holding the cover in place and pull out the cover.
6. Slide out the old cabin air filter and dispose of it properly.
7. Insert a new cabin air filter into the slot, making sure it is oriented correctly.
8. Replace the cover and secure it with the four screws.
9. Reconnect any wires attached to the glove box and push it back into place.
10. Close the glove box and restore any items inside.
Book a service appointment: If none of these steps work, there may be a hardware issue with the car’s climate control system or a sensor.
In this case, contacting Tesla support or booking a service appointment may be necessary. Tesla can diagnose and repair any problems with your car and restore its functionality.
Why is Tesla Climate On Failed?
#1. Poor internet connection
One reason why Tesla climate on failed could be that the car or the phone had a weak or no internet connection. This would prevent the app from communicating with the car or the Tesla servers.
To fix this, you can check the wifi or LTE signal and move to a better location.
#2. Low battery level
Another reason why Tesla Climate on failed could be that the car’s battery level was too low, below 20%, to activate the Climate remotely.
This is a safety feature to prevent the battery from draining completely. To fix this, you can charge the car to a higher level.
#3. Software glitch
A third reason why Tesla climate on failed could be that the app or the car had a software glitch, causing the climate function to malfunction.
To fix this, you can restart the app, reboot the phone or the car, or update the app or the car software to the latest version.
#4. Faulty sensor
A fourth reason why Tesla climate on failed could be that the car had a faulty sensor, such as the cabin temperature sensor or the HVAC sensor, that prevented the climate from turning on.
To fix this, you can book a service appointment with Tesla and have the sensor replaced.
#5. Malfunctioning burner
A fifth reason why Tesla climate on failed could be that the car had a malfunctioning burner, that emitted high levels of nitrogen oxide and triggered a system fault.
To fix this, you can book a service appointment with Tesla and have the burner repaired.
#6. Semi-covered or underground parking lot
A sixth reason why Tesla climate on failed could be that the car was in a semi-covered or underground parking lot, where the app could not access the car’s location or status.
To fix this, you can move the car to an open area where GPS and LTE signals are available.
#7. Temporary server issue
A seventh reason why Tesla climate on failed could be that the app had a temporary server issue, that caused a delay or an error in sending or receiving instructions.
To fix this, you can wait for a few minutes and try again.
