lol....if u do a poll on rear windows that worked...about 2/3 out there are broken. the problem is the motor for the rear window is mounted in **** a way that when it rains it gets in back tail gate and on to motor(one of 2 design flaws on our babys

....if u want to try and fix it. take the inside of tailgate apart. u will see that after u take off the metal panel that the middle has the motor mounted on the back of that. disconnect the plug to the motor hook up a volt meter to plug to the wire. and turn on truck and flip window switch...see if that sends power back to the motor. if the volt meter moves then its the motor. if its still dead. try the key in back. if that works switch is dead. and if all elce fails check fuse and wires to make sure non are loose...just remember when it rains try not to use window.
