Power Window Problems

[QX4charger]

I have a 2000 Infinity QX4. I'm having power window problems on a car I just bought. Problem 1 with power windows: Front passenger window works from main switch but not from passenger switch. Changed passenger switch and still does not work. All connection pins are all the way up in wiring harness. Problem 2:The 2 rear windows go down from main switch, but do not go up from main switch. BUT, go up and down fine from rear switches!!

Problem solved! Changed main switch (which fixed problem with rear windows not going up from main switch). Also, when i originally changed switch on passenger side, I left the original door lock switch (which worked fine) plugged in. This must have had some effect because when i changed out the door lock switch AND the window switch (two different plugs) it worked fine.
