Only front windows don't work

Does anyone know why only the front windows don’t work on a 2008 Pathfinder? The switch panel on door controls locks & back windows work. Is there a way to tell if regulator is bad or part of switch panel?

The front switches are likely broken. You test it by checking them with a multimeter set on resistance.

The BCM controls all the functions of the power windows.

A dealer level scanner would be required to determine if that was the cause.
