there is a relay on the right side of the dash , in the door opening i believe , the harness should , and i say that loosely , unplug in the door panel , it breaks off in all directions to each door and back to the dash , chev pont and buick should all be the same but they are all different, you may find it goes through the door , you can pull the panel and trace it , the dealer should be able to supply you with the harness, i have replaced them before , dont forget to check that relay , there is a reason for this problem , if you have an ohm meter you can check for resistance at the plug the input side and try and trace the problem down , it burned for a reason

Suggested Repair

Check the power-window relay on the right side of the dash near the door opening, then trace the door harness from the panel plug. Replace the burnt connector or harness, which the dealer can supply, and use an ohmmeter at the plug input to find the resistance or short that caused the burn.

Conversation Summary

The owner of a 1999 Buick Century Custom replaced the master window switch, but the windows still would not go up. The connector at the end of the wires was burnt. The expert said to check the window relay on the right side of the dash near the door opening, trace the harness through the door panel, and replace the burnt harness after checking resistance to find why it burned.
