Bets pain in the a$$ part of the car! Pull the vent screen and the two little sheet metal shields, then pull the left fresh air vent under the dash. Both will give you great access to the pulleys and cables.
The cable ends on the large drum are arranged with the drivers cables in the front two grooves and the passenger cables in the rear two groves. They are in there correctly when they do not cross each other. ie, the drivers side upper cable as seen from the cowl vent side goes in the second groove from the front, the lower cable goes in the front groove. Use masking tape to hold the front in place while you do the second groove, tape it down, then pull the pin on the pulley block and start on the passenger side with the same process.
