To get the cluster out remove the underdash panel in the foot well. Then reach up behind the cluster and push it out. Sometimes they are a tight fit so you might have ot push kind of hard.

Can you hear the motors working when you push the buttons. There is a chance that the teeth on the window regulators are broken off, so that the motor has no teeth to grab.

I would check to make sure you are getting voltage to the window motors. If you are then the motors are and the windows aren't working then you have a bad motor. If not they you have a problem upstream somewhere. Probably not the switches since they are new. I'm guessing the motors are bad.
