Passanger window keeps moving to half up (or half up (or down)

Most likely your vehicle has automatic windows. If this system is failing or needs to be relearned, this can cause the issue you are describing. I recommend having a shop perform a relearn procedure for the automatic window first. If this does not work, then you will need to have the problem fully diagnosed to determine where the problem is; i.e.- power window module, power widow regulator, power window switch, wiring fault, etc.
