hi, have you checked the wiring harness between the door and door jamb -drivers side door first try wiggling the harness while holding the button for any window that isn't working and see if that window budges or moves a little .

you have a fuse box under the back seat for different things/circuits including the windows so check the fuses there if you haven't already .and check all of them (always a good thing to do )
usually you will here a click when you try that window or any windows that usually indicates the the module in the door is responding to the button ..
there is power to the window but it uses a ground signal to work which the switch supplies .and then it switches polarity when used for the opposite direction ..jazzmaster ..
