I have a 2004 Sonata. I moved the power seat all the way forward to vacuum the back seat carpet and now it will now power back. The power back rest works and the power seat moves up and down but not back. I have seen other car manufacturers where you can remove the power seat cover and you can move the seat back manually. I removed the cover but do not see where you manually move the seat back using a square bit or other? I did see this small screw kind of a phillips but phillips head does not work it slips not even sure this is what rotates the long screw to move the seat back on the track..
