How To Reset Windows

[lexus GS400]

Hi all my friends.

I have a 1998 GS400. after I change the rear window glass. when I close the window with auto option it automated roll all the way up and down about half way and stop.

I try to reset the computer by this way. unplug the regulator motor and hold up the switch fo about 10-15 second until I hear a click on the box. but the problem still the same.

please help me with this matter.

thank you in advance

As long as you did not detach the motor from the regulator, press the down switch all the way down and hold until the window is fully open. Lift the up switch and hold until the window is fully up; continue holding the switch up for a few seconds. That should do it.

If you did separate the motor from the regulator assembly, the instructions to reset are a bit more complex. See the attached .pdf

This works. Just be careful of your tint. Try pushing the window up before removing/installing motor

From my experience, you may also hear a little "click" (it helps if you're in a quiet place) when the automatic window feature works.

Push down switch and hold down.

(lowers, stops, then a soft "click")

Pull up on switch and hold down.

(raises, stops, then a soft "click")

Thank you for all the information posted.

I have tried the reset method and it seems to work once or twice and then the window reverts back to the same problem before (all the way up and then halfway down) Any advice? Thanks!

I had the same problem on my 2001 ES300: When I use auto to roll the passenger window all the way up it goes up and then down to about half position.

I tried the method of holding the button down for a while than up while holding for a minute to try the easy reset. That did not work for me.

I used the procedure in the PDF and that did work for me. The write up is not easy to understand, so here it is what I did based on my understanding of the write up...

1. Roll the window down, below half way, so that you can unbolt the nuts from the glass and the two plastic stops on either side bottom (use a sharpie to mark exact position of nuts stud to glass so you can mount in the same position). Remove the glass. Unbolt the regulator (both nuts on top and the nylon nuts on the bottom). Leave in the door but slide a bit over to the right to make room. Unbolt the motor and undo the wire harness. Move the motor to the right so you can get to it through the large metal panel opening in the door (you have to remove the 4 or 5 screws). Unscrew the two small screws holding the sheet metal cover of the regulator gear/pulley to the motor. Carefully remove the pulley from the motor. Reattach the wire harness to the motor and activate the motor for 5 seconds in the up position. Align the square of the motor to the regulator gear/pulley. Replace the two small screws and reattach the motor and the regulator. Then reinstall the glass. In manual mode open and close the window a few times. Then try automatic. Worked like a charm for me.
