2002 Hyundai Sonata power windows

Driver window controls cannot open rear driver side window, passenger front and back windows. The windows can be opened using the actual controls for those windows. Driver can close those windows using the driver window controls. The driver window can be opened and closed using the driver window controls. I was able to open the driver side rear window this morning using the driver window control but later in the day could not. I am concerned that the same thing may happen to the driver window. The driver controls can close all of the windows. The AC in the car does not work (there is a leak) and I need to open windows on hot days to get air flowing through the car. I bought this vehicle several weeks ago from a private owner after the motor in my car completely died. I was initially able to work all of the windows but one by one, the driver controls cannot open them, I am afraid that soon I may not be able to open the driver window either. I am sorry that I am not able to submit a donation for an answer, money is very tight. Any input you can provide will be greatly appreciated. Thank you :)
