Hi, I got the problem of Passage side window. This was only down position with switching up or down, fortunately, the window will be up position by chance. After while, the motor regulator is dead. Finally, I have sending to my repair shop to replaced new motor regulator. But another problem coming!! The window work good with Master or Passage side switchs. But the window will be going down to half way once touch to the top. I have to tried my switch on other RX300 is work good. I'm really don't know what happening on the window. I believe some relay will be related with this problem, but I not sure my diagnosis is correctly. Anyone can give me your hand please? Thanks

Did you reset the pinch protection?

Hold the button up (instead of single flick) till the glass moves all the way up. Hold it down till the glass moves all the way down and then try the single flick to see if the glass would move all the way up.
