Hi Boneea , double check the fuses or just replace them , the windows should be on 2 fuses (one frt window ,one rear window , on opposite sides per fuse ). They can look OK but aren't . After that you will have to start tracing the circuits to determine the cause , though it's unusual for all windows to go out . Did you just buy the car like this or is this a spontaneous failure . Good luck .
