Pretty common problem, few things it could be
mine was a combination of the relay and the door button panel.
to get it up in the mean time, take your battery out and put it next to the door, then take the door trim off, theres a little plug that you can disconnect that goes to the motor which goes through a hole.
wire up the positive and negative to the battery and touch them on the terminals going to the window motor, if it doesnt work then switch the terminals.
i stripped back the ends of some speaker wire and twisted them together at each end (obviously not the same one that goes to each terminal)
once that's done you probably just need a relay, either that or the button is locked on auto, it's a common problem like i said.
find out which door button panel you have, theres one with a black backing and one with a white (they're different wiring structure if i remember)
but go to an import spares place and just try a relay and a button panel individually, see where the problem actually lies. mine was unluckily in both
good luck
