Master Window Control Switch

Hey guys its been awhile since I posted anything but I need help before I go nuts. My driver's side window switch won't roll down either of my windows, but the mirrors and door locks work. The passenger window switch works just fine but only on that side. We have been having100+ temperatures here in Baltimore and I need to roll my windows down. Can someone please help.

sometimes fuses make incomplete circuits throughout the system.
just check all the fuses that look like they have something to do with window actuators.
One time my A/C LCD was not working at all. replaced the "cigarette lighter" fuse and it worked.
You just have to look around.

I've tried testing a known working master switch; this was not the issue. wiring looks fine at surface level, i also believe that it has to have a closed circuit for the passenger window to operate so im doubtful that this is the issue.

im going to prod around more in the daylight but i figured id ask here.

There is a diy thread on this...you have to take apart switch and clean the carbon off the switches.
