I have the same problem with my Kia Optima 2005.
It's really ennoying getting into the car. I suppose that the actuator is malfunctioning, but my problem is: How do I get a new actuator, and who is going to repair it. I live on the island of Bonaire, Netherlands Antilles. The main problem is that the door must be open for someone to remove the inside cover. It took me some time (more than a week) to open the door myself and remove the inside door cover. So now I have the cover removed, but when I closed the door, it locked again so I still get into the car from the passenger side. And everytime I want to open the window, I have to plug the sockets into the switches. Is there someone who knows where I can get a new actuator? I'm really hopeless.
