open up the door skins, take a 12V test light to the connections and see if you're getting power when you press the button. also check your connections to make sure they are seated fully, as i had that problem after replacing a power window motor once. if the windows are in the tracks properly, the arm is connected to the motor securely, and the spring (should be a spring to assist the lifting) is there, AND you've got power at the connections, then you need to replace the motors. Not sure what they run for a civic, but i paid $50-ish for one for my 91 Blazer. Diagnose and go from there!
