I need to figure out if my power switch is failing or is it my power window motor, driver side Mechanic's Assistant: Have you checked the fuses? I have checked the fuses inside of the car below the steering wheel Mechanic's Assistant: What is the make/model/year of your car? 2013 Kia Optima Ex Mechanic's Assistant: Are you fixing your EX yourself? What have you tried so far? Yes myself, and so far just the fuses in the vehicle not under the hood. Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? The driver window can go down but it will not go back up. All other windows works perfectly with the master switch but only having trouble with the driver side window going up.

Hello, my name is John. Since the window will go down then you know the power and ground supply to the switch and to the motor are good. You also know the motor works. The only thing the switch does to make the window go up instead of down is swap the power and ground on the 2 wires going to the motor causing it to run the opposite direction. So this being the case, I suspect he switch is at fault.

I need a new power switch?

Yes, that is what it sounds like to me.
