Sunroof was very slow when it was opening, then I tried to shut it and only the passenger side closed completely and the motor started to make a clicking noise. Ripped it apart and it looks like the drivers side cable is seized and no amount of pressure on the cable and sunroof will move it. Passenger side cable moves freely and i can open/close the sunroof with a set of pliers.

Are they cables replaceable or is it more likely the sunroof itself is stuck?
