Need Help - Ls400 drivers window goes down by itself
#2
Pole Position
Hello,
Does it drop down or goes down as if the switch is operated?
Seems like your only option is to start digging into the window regulator. First, try disconnecting the motor pigtail for the Regulator and see if it will cure the issue, if not, then you need a new regulator. If it will help, then you need to look into the wiring.
Hope this helps and best of luck!

Hello.
Thanks so much for your quick and quality reply.
I have never seen the window go down because it only happens when the car is UNOCCUPIED AND WITHOUT THE IGNITION KEY.
it’s doing it 2-3 times per week now, rain or shine. I called Lexus, but they didn’t have a clue.
If I pull the fuse or fuses, will the windows stay up ??
Thanks

Long shot but try to "reprogram" or "re-calibrate" your windows. How this is done on most vehicles, you usually want to roll it down normally and then roll it up without the auto feature by keep holding the button up even after it closes for about 30 seconds or so. That usually tends to recalibrate the window switch and tends to fix those type of random issues. IF it doesn't then you definitely have a much deeper electrical issue that may need diagnosing. Calling the dealer won't do you any good cause they're not going to diagnose anything for free.

I will try your reprogram suggestion and follow up with the results.Thanks so much.
