front window wont go up or down

Hi, I'm one of the auto experts on RepairPal's Car Genius team! Great question, sorry to hear you are having issues with your 2015 Buick Verano. A window that won’t go up and down could be caused by several different things. It could be the switch, the wiring to the window motor or the motor itself. This is something that generally requires the use of a volt meter to check for signals and isolate the source of the issue. I’d recommend bringing it to a shop that has qualifies techs and access to the proper equipment to trace the wiring diagram and locate the point of failure.
