Driver's window won't go up

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! It sounds like your 2011 Buick LaCrosse has a mind of its own—rolling down but refusing to go back up. Since you’ve replaced the switch and you're getting power, the culprit might be a faulty window regulator or a problem with the wiring in the door, particularly the ground. Also, check the motor itself—it could be tired and only working one way. A good test would be to try tapping on the door near the motor when you hit the switch. If it starts working, the motor might be on its last leg. If you need any further advice or want help finding a trusted RepairPal shop in your area, please feel free to call us at 877-913-1554!
