Rear Side Windows do not operate
 

My rear side windows do not operate when I press on switches in my 2001 Saab 9-3 Convertible.The front windows do operate and when I press the dual windows switch only the front windows operate.I have checked the rear side windows fuse and it is good.When I press the rear side windows switches I hear a clicking sound at windows.I have not tried to lower windows by using Roof switch for lowering soft convertible nor taken out Master Power Switch Module.Has anyone had this problem before I investigate further.Thanks
