Thanks for using Just Answer, your vehicle is not equipped with a SJB, but it does have a CJB (Central Junction Box), which is located on the passenger side of the vehicle.
Thanks for coming to Just Answer to ask a question.
The previos expert has opted out, so I will help you.
Ok if you have no power at fuse 401 then the relay is not closing the switch or there is a circuit board concern i nthe junction box. The relay needs power on pin 86 and ground on pin 85. Pin 30 should also show power. If 85 and 86 are good then the switch will close and allow pin 30 to send power to pin 87 then to the fuse 401.
Remove the relay and supply battery power to pin 87 and see if the fuse 401 gets hot and see if the windows work.
