It is common for the cable to wear out with age. You should replace the whole window regulator assembly, AFAIK there is no official replacement for the cable, my brother tried to replace it and he ended up replacing the whole regulator because the cable kept braking at the ends of it.

To remove it you have to drill out the 3 1/4" rivets holding it to the door. Since you'll be removing the regulator and the motor, it would be a good idea to replace the motor nylon bushings too, these can be bought at any autoparts store like autozone, advance auto, etc. Look for a red blister and HELP! brand.
