It's not worn out or binding. I have a new main switch for the drivers door to see if the switch is bad. All the ground are looking to go back to the drivers door switch so we will see. I believe the yellows wires are the grounds to the switchs. Theres one red hot and two browns that goto the window switch and two yellows for grounds one for up and one for down. This is what I'm thinking with fords F--- up wiring.
