I have a 2002 jeep grand cherokee limited 4.7L and just today I realize that my passenger side doors have no power whatsoever. The windows won't go up or down, doors will not lock or unlock, nor does the door light work when the doors are open. I am puzzled... I can roll down the driver side front and rear window with master switch but when it comes to passenger side everything is dead. None of the doors lock or unlock including lift gate. If anyone knows anything please help. The moon roof does work. Any help would be appreciated, thank you.
