S21-2 and s21-1 are the power window switches, have you checked continuity / swapped left to right?.

Also, the express down function works by first triggering / holding down then triggering the up wire.

Find the module that controls the windows. On my car it is under the rear seat cushion, left side. Clean all eight relay contacts. There's a relay for up and a relay for down, for each of the four windows.
