The rear windows will not go down when pressing the master button or each of the back buttons, the front windows operate normally. Any ideas?

Hey Doug, it sounds like the master switch has gone bad which is where the power runs through of the rear switches. Here is a guide to help you test and replace the master switch and wiring diagrams so you can see how the system works:
