What to Do If You Have a Loose Window

If this bottom window is loose and will fall if not held, one solution is to pull the window out and adjust the springs. Start by pushing the window into the deep side of the track and pulling it out.

You’ll see two springs on the ends. These springs can pop out easily. Bend each spring into more of an arch to increase the tension in the track, then pop them back in.

Now, with the springs arched, put the window back into the track, starting with the deep side first. The window should now slide smoothly and stay in place, providing the right tension.

Summary:

To fix a loose window, remove it from the track and adjust the tension springs by bending them into an arch. After adjusting, reinstall the window into the track with the deep side first. This will help the window slide smoothly and stay in place.
