f150 2014, one window works three others do not . Relay switch is good, fuses are good , wires in harness look brand new, new master window switch installed. Yet, outside key pad and power mirrors and power locks on drivers side door do not work? Any help before I have to take it in would be greatly appreciated.

 

From your description , it sounds like there is a broken wire in the system and most of the time it is in the driver's side door hinge area..

A good shop should be able to verify that, and make the necessary repairs.
