Driver side window doesn’t roll up

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. So sorry to hear you're having trouble with your Optima. If you can hear the motor when you try to roll up the driver-side window, but it doesn't move, the issue may be the window regulator rather than the motor itself. The window regulator is the mechanism that physically moves the window up and down, and if it's damaged or worn out, the window won't move even if the motor is working. Another possibility is that the gear that connects the motor to the regulator is damaged. It's also possible that the window has come off its track, preventing it from moving correctly. Since you can still hear the motor, it's a good sign that the electrical system is working, so focus on the regulator or the track as the most likely culprits. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
