Although Tesla has highly efficient automated window operating systems, sometimes they cause unwanted hassles. Tesla windows rolling down by themselves is one such issue. But why do Tesla windows roll down without any command?
Tesla’s window safety feature automatically rolls down the windows a bit as you open or close the vehicle door. If the windows roll down otherwise, it can be an electric issue or software glitch. Also, Vent mode activation, window misconfiguration, or a broken window regulator can be the cause.
Let’s explore the causes of why your Tesla’s windows roll down and how to fix it.
Why Do the Windows on My Tesla Roll Down? – 7 Possible Causes and Fixes
According to Tesla, the windows of your Tesla are supposed to roll down automatically whenever you close the door or open it. This added safety feature avoids damage to the window glass in case you slam the door too hard.
However, when your windows roll down all the way, even when the doors aren’t active, that’s a different issue. Here are the reasons why it happens and how you can fix it:
Vent Mode Activated
When you activate Tesla’s Vent mode using your key fob or Tesla app, it allows you to open the windows remotely. If you accidentally turn it on, your Tesla windows will roll down even when you’re not around. In this case, the windows will roll down only a few inches.
How to Fix?
To turn off the Vent mode, open the Tesla app and tap ‘Climate.’ Now, look at the bottom right corner of the screen.
If it says ‘Closed,’ the Vent mode is turned on. Tap on it, and the button will now say ‘Vent.’ It will shut off your windows as well.
Software Glitch
Tesla software updates are released regularly, and sometimes, they can introduce new bugs or glitches.
If you notice that your windows are rolling down unexpectedly after a recent update, it might be caused by a software glitch. Also, not updating the software timely and using a particularly old version of it can cause this issue.
How to Fix?
First, you need to install the latest version of the Tesla software. If the windows keep rolling down after the update, you need to reset the software. Here’s what you need to do:
- To update your Tesla software, go to the ‘Controls’ option on your touchscreen. Select ‘Software,’ and you’ll see the download option if any software update is available.
- As for a software reboot or reset, you need to hold down both scroll wheels of your Tesla for about 10 to 30 seconds. During this time, the touchscreen will go off and turn on again, indicating that the system reboot is completed. Follow this video to understand the process better:
Window Misconfiguration
Each window on your Tesla has its own configuration settings. If a window is misconfigured, it can roll down unexpectedly. Similarly, calibration errors will trigger the safety features of the vehicle, causing the windows to roll down to avoid damage.
How to Fix?
First, double-check your window settings to ensure they are correctly configured. After that, you need to recalibrate the windows to clear any errors. For this:
- Close the driver’s side door and use the window operating switches to raise the malfunctioning window. Hold the switch for at least 5 seconds, allowing the window to stall.
- Now, let the window roll down and hold the switch for 5 seconds, just like you did before. Repeat the process to fix the calibration issue. Check out this video for some visual aid:
Broken Window Regulator
As the name suggests, the window regulator controls the window movements when you open or close them. Due to repeated flexing, the regulator motor and connected wires can easily get damaged. It often leads to erratic window behavior, including rolling down randomly.
How to Fix?
In this case, you need to get help from an expert mechanic to test the window regulator motor, related wires, operating switches, and even the control module.
The damaged part must be fixed or replaced as needed. You need to spend around $305 to $410 for the replacement.
Bad Window Power Switches
The power window switches operate each window on your Tesla. When you press them, the switches send signals to the window regulators to open and close the windows. If a power window switch is bad, it can send wrong signals and operate even when you don’t press them.
How to Fix?
Again, you can’t fix the power window switches at home. The problem might be switches, related circuits, or a blown fuse. Contact your Tesla dealer or a professional mechanic to fix them. The total cost can be up to $350, depending on your location and Tesla model.
External Obstructions
Similar to many modern vehicles, your Tesla also has a safety feature called Auto Reversing System. The vehicle uses several sensors to detect obstructions while closing the window.
Upon detecting any external obstructions, the windows reverse instead of going up to avoid unwanted accidents. Sometimes, the sensors might malfunction and roll down the windows when they detect debris, ice, leaves, or other external obstructions.
How to Fix?
Before you go for a professional diagnosis, first, check if there’s any debris or ice stuck in the windows. Thoroughly clean the power windows and see if the issue persists. If yes, get professional help to test the sensors.
Electrical Issues
Your Tesla depends on its electrical system to send signals to the control module that operates the window functions. Short circuits in the wiring, blown fuse, faulty relay, broken cable, etc., can cause one or more windows to roll down.
If the electrical system has any issue, the windows, doors, and related parts might occasionally malfunction.
How to Fix?
To diagnose and fix any electrical issue on your Tesla, it’s best to contact the Tesla support team. If your warranty has expired, you can also get professional help. The cost is typically between $88 and $111.
FAQs
Now, let’s take a look at some common queries Tesla owners have asked regarding the window rolling down issue.
To force a Tesla window up, first, slam the corresponding car door while pressing its power switch. This might reactivate the window regulator motor if it’s jammed. If this doesn’t work, grip the window glass with both your palms and manually pull the window up.
Yes, your Tesla windows can roll down in freezing temperatures due to its automatic roll-down feature. Frameless windows automatically roll down a bit to prevent window shattering by frozen materials.
Wrapping Up!
While answering the question– why do Tesla windows roll down?- we’ve explored all the possible causes of this issue. In most cases, a simple reboot, vent mode deactivation, or software update can fix this problem.
Also, you need to inspect the window tracks for any obstructions or damage. If you find any obstructions, remove them and clean the debris. In case the problem persists, take your car to a Tesla service center.
