'04 drivers window dropped

and I can see where a cable has come unhooked on the left side but according to the useless manual you must first remove the glass from its holder but I can't get the window to come up far enough to access the window securing bolts. Any veterans on this subject.

Well. i bought a new regulator/motor and installed it but it is working in reverse. The up is now down and the down is up. Does this dc motor/controls just swap the polarity of the two wires leading to the motor. In other words can I just swap the red and black wires so that the button will work right. The new assembly came with a attached cord that replaces the one that went from the motor to the connector mounted on the door
