The drivers side electric window will not open on my 2006 Renault Megane?

I recently bought I Renault Megane. Last week the boot would not open and the sensor had to be replaced. Did not mind so much as only cost £30 to replace and I fitted the party myself.

The drivers side electric front window will not open. It makes no noise when pushing the button and there is no movement whatsoever.

Does anyone have any ideas?

Thanks
