The window on my Tesla will not go up all the way – What is the problem? How do I fix it?

A common issue with most cars that have frameless windows for their doors is that when ice builds up during winter the car thinks the window is blocked so to prevent damage to the motors the car decides that the motor position is now at a lower point.

This can also happen if someone were to try and block the window with a finger etc, instead of allowing the finger to get crushed it will stop short to prevent damage to anyone but it may then need to be reset.

How to solve/fix:

  1. Ensure the window is free of any obstacles (including ice/snow/grit/dirt)
  2. Try to close the door, lock the car, and then get backing the car and press the button to raise the window
  3. If that fails, press the window button downwards for 10 seconds, the repeat upwards for 10 seconds and again downwards for 10 seconds. The window hopefully will now go all the way up.
  4. If still nothing try a full reboot
  5. If this fails you will need to contact Tesla to solve (in the meanwhile it’s important to cover the gap to ensure rain doesn’t enter the cabin)

How to prevent this from happening in the future:

  • In cold weather on the mobile app, navigate to Climate > Defrost
  • Use the mobile app to schedule a service appointment where Tesla can provide hydrophobic coating to your windows for a nominal fee.

Remember modifying your vehicle may invalidate part of your vehicle’s warranty.
Therefore, be careful and check with Tesla if unsure. Also any modifications will most likely need to be OK’d with your car insurance company.
