1997 Altima ignition problem (i think)

[Aflaack]

Heres the deal:

About a week ago all 4 of my power windows and sunroof just stopped working...

Checked all the fuses twiceChecked all the relaysMetered the wires coming into the driver side switch.Door locks still work (on that same switch block in the driver side door)

Im getting power to the switch where im supposed to, and im even getting power to the sunroof switch in the panel above the rear view mirror.

my next logical idea was the secondary ignition wire, except i dont know where it is. My guess is that the car has 3 ignition wires and the windows and sunroof are all on the secondary ignition wire and there is a short ... or something wrong there.

any advice on other things to check... or idealy a electrical schematic for the ignition system.
