1998 Buick Century Electrical problem

Electrical problem
1998 Buick Century 6 cyl Front Wheel Drive Automatic 115k miles

yeterday my 98 buick centrury's windows all of a sudden stopped working and didnt roll up. But made a clicking sound when pressed down.I also noticed the power seat wasnt working, and the door locks wasnt working when the car was on. Also the headlights turn off right away once you turn car off, and they usually turn off after about 5min. And im not sure whats wrong
