my wife's 2002 lexus has begun to have a problem with the driver side front window. It will not roll up after being rolled down for say a trip through a drive-through window or something. Sometimes it starts to go up and then acts like it is kinda falling or slipping back down in a short jerking motion. Sometimes it just stops. No popping or gear grinding noises at all which leads me to think it is more electrical than mechanical but thought I would ask here and see what kind of responses I get.

any feedback is appreciated!

Thanks,

Thomas
