How do i Change the headlight in a 2000 pontiac Grand Prix?

Ive got no idea.. Help please?How do i Change the headlight in a 2000 pontiac Grand Prix?Most all new car headlights are replaced from the rear of the assembly. Sometimes you have to pull the assembly out then turn the large knob / clamping nut. Then pull the socket out and the bulbs is pushed into the socket. Good Luck.
