Electric window mechanism

[cbates10]

First of all, hi to everyone as im a newby on here.

I have recently had a bump in my megane and had to get a new rear door. I have managed to source one second hand however that was manual windows and mine are electric. I am now looking for advice on how to remove my electric window motor, runner etc from my damaged door and put into my new door. Can anyone help with a how to on this please?

Thanks
