I dont see a circuit breaker in line for this model here for these components.I see some fuses and a relay.

Double check and make sure fuse 6 (60 amp) and fuse 47 (30 amp) are both o.k. in the battery junction box fuse panel.

In the central junction box fuse panel make sure fuse 17 (15 amp) is o.k. as well.

Locate the accessory delay relay in the central junction box fuse panel and tap on it to see if the windows and components start to operate again then.If they do then this relay needs replaced.

If these are all o.k. let me know.

If these are all o.k. let me know if you have a test light or multi meter.

Thanks Pete

The battery junction box is located under the hood as shown here

The central junction box is located under the dash on the drivers side and is shown here.You can see where the accessory delay relay is located in this diagram below.

Let me know if you locate any issues here at all.
