There's a kind of 'extra bit' to the switch you just need a bit more pressure (not that much) and the window will open or close fully.
Can I be the first to introduce you to the 'Remote window closing' function? I didn't know it existed untill someone on here told me so......Anyhoo, upon leaving the car (leave your window(s) down still) then press AND HOLD the lock button on the remote fob and the window(s) will close themselves
