Yes passenger windows went down, wont go up.
flip up armrest , remove screw, remove switch, disconnect switch so you can take it to bench or kitchen table.
Use small screwdriver on sides of switch between black and white to ease out from lock bumps.
small part that slides to and fro can now be removed, again by screwdriver easing the sides out that hold it.
BEWARE there are two small springs and ball bearings, dont loose them.
Find spots where carbon has built up on contact points, clean up with fine sandpaper.
I found it VERY difficult to keep springs and balls in correct place as i reassembled.
SO
Take small part of switch that houses springs, using a tiny screwdriver place tiny bit of silicon sealant on end of spring.place the spring home.
Now put a tiny amount of silicon on the end of the spring you can see, carefully place balls on top of springs.let dry for a few hours.
Now the switch can be easily reassembled.
Good luck
