Hi can anyone help me out here my rear defogger doesn't work or even light up push the button on. The wires on the window are still good. If anyone can help me that would be greatful.

Find the relay and check that circuit from the switch to the relay check for 12v to the relay when the switch is engaged. Assume you checked for 12v to the window and a good ground on the other side, to say the least your info is sketchy, including the car info!
