both back doors dont unlock threw the main switches only unlock manually, and both rear windows dont roll down threw any of the switches, anyone have any idea what this can be? do windows and locks run off the same sensor maybe?

Try replacing the window switches. The auto locks and windows are both controlled through them.

the switches on the driver door and on the rear doors do NOT control them though.. what switches would i need to get? all or just main panel

How do you know?

because when i press them up or down the windows dont move, they dont even make a sound.. i do have a circut tester i guess youd call it? it hooks up to a power and u touch the probe to the other connetion and the green light either goes on or doesnt go on
