all power windows won't work. all the fuses are good. No power on any
2007 Jeep Liberty Sport 4x4. I am looking for the power window relay. I am open for any other tips on this power window issue. I have checked all the fuses and they are good. traced all the wires from master switch to kick panel wires all in good shape

Without wiring diagrams, this can be difficult to troubleshoot. With all power windows inoperative, there may be a ground issue related to all the power window motors. Most vehicles should have two main ground connections; battery negative to chassis and chassis to engine block. All negative connections are either to the engine block or chassis at various ground studs to tie in all circuits to ground.
Sometimes the main window switches wear out and may be disassembled to clean it of dielectric grease from heavy duty brass contacts and rejuvenated with new grease to restore full function.
