Front windows only go down half way

Recommended Posts


ere are a few steps you can try to fix this issue:

  1. Reset the Windows: Go to the local switch at each window (not from the driver’s door) and manually run the window full down then full up, and hold the switch in the up position for a count of three. This must be done at each door, as each window is individually manually reset by doing this.

  2. Power Window Problem Solution: With the ignition in the ON position, take a seat inside the car next to the problem window/door. Open the door. Depress the window switch (as if to open the window). While depressing the window switch, use your other hand to slam the door shut. The window should now function normally.

  3. Driver Side Window Solution: Fully close the power window by fully pulling up the multiplex network master switch assembly or power window regulator switch assembly, and hold the switch for 6 seconds or more after the window is fully closed.

If these steps don’t resolve the issue, it might be best to consult with a professional mechanic or a Lexus service center.
