Hi Mike, my name is***** are separate fuses for each rear window. Fuse 18 under the hood and fuse 2 in the battery compartment. First try disconnecting the negative battery cable for a few minutes then reconnect it and see if the windows work. If the controller area network got corrupted it can cause the problem.
Let me know if it works.
