XF passenger front window

[AJD]

Hello guys.

I am new to the Jaguar owners club, hope I'm doing this right.

Can anyone help me with this please. It's a small issue that's driving me mad!

Jag XF (2010) premium luxury. 

N/s/f window fault. The window works well with the exception of the one touch opening and closing, the window will open and close in stages only. I have disconnected the battery and reset all windows, all others open with one touch before and after the reset procedure and then close with one touch after reset. Nsf will not even open with one touch let alone close.

I have now swapped the switch on the door itself with the rear door, changed the window switch unit on the drivers door, changed the nsf door module (this is supposed to control locking, folding mirrors and window mech) the only thing left is the window mechanism itself which is over £100 to buy, used, so I'm reluctant to do this if it's not going to work.

Any ideas?
