HELP window wipers!

Right my front window wipers have just seized and will not work! I have checked all fuses including engine bay fuse box! Moved relays around and had the motor tested at a garage, everything is working but still no window wipers. When I plug the clip into the motor and push the stalk down the motor doesn't turn at all, this is making me think its getting 0 power at the connector that plugs onto the motor any ideas what too do next ?
