Scenic 2, no power to rear elec window

Hi everybody, hope someone can help. I have a 2004 scenic 2 all windows work apart from rear driver side. The window motor works fine and the regulator was switch to a mini cube QT module. The fuse for the rears windows is fine as the opossite window works. When I check for any power at the window switch connector I'm not getting anything. Some help would be grateful.

Thank you,

Dominic
