We expect our car windows to seamlessly slide up and down with the touch of a button. So when they don’t operate as they should, we need to understand exactly why. Is it a simple fix or a substantial failure?

In this video from the experts at Delphi, we show you how to calibrate the front windows of a 2015 BMW X5 following a reported fault with the ‘one touch’ feature.

With step-by-step troubleshooting instructions you’ll learn how to quickly pinpoint the problem and fix the issue. The video covers:

What can cause car window failure?

It could be anything from the battery having been disconnected and reconnected, the door itself or the door module having been replaced, a blown fuse, or switch failure. That’s why it’s important to run a diagnostic test on the car.

Do I need a diagnostic tool to calibrate a window?

That depends on the make and model. If you don’t have a diagnostic device to hand, try taking the window up and down several times in succession, holding the switch for a few seconds at each end of the travel . This will carry out a self-calibration on the window, but as mentioned, this method depends on the vehicle.

Does it take a long time to run a diagnostic test?

No. With the right diagnostic tool you can have an idea what’s wrong in a few minutes.
