Richard Hewitt Posted April 5, 2011 Share Posted April 5, 2011 The driver's side window on my '02 LS 430 is failing to open all of the time. The sill is trying to expand, indicating the glass plus the tint app may be expanding. Should I be thinking replacement of the motor?

1990LS400 Posted April 5, 2011 Share Posted April 5, 2011 If something is causing too much friction or impeding the movement of the glass, maybe the "pinch protection" feature is kicking in and preventing the window from opening. Maybe remove the door panel and take a look? Quote Link to comment Share on other sites More sharing options...

A high resistance spot on the contacts will supply some current to the motor...enough to cause it to attempt movement but not enough to get the motor really going. Sometimes it works, sometimes not. Characteristic of worn or dirty switch contacts. Quote Link to comment Share on other sites More sharing options...
