I have an 02 Impala with the police package. I am trying to get the rear windows to work from the back seat. Anyone know where they are disconnected at? I reattached the door handles the other day and checked to see if the switches were hooked up and they are. So Im not sure where to check next. Any help would be greatly appreciated.

Have you checked the fuse block? Look at the diagram and find which fuse operates your rear windows and see if they removed it and if so verify what amp fuse it takes and replace it, that may fix the problem.

Figured it out. One of the wires at the switch was disconnected and taped back into the harness.
