The car 2000 Ford Crown victoria
1)The door lock switch on both side only works when it wants to! I tool the whole thing out scrub it no luck seems the prev owner put grease on it before, I also switched the switch from the passenger side to see if it’s the switch but no luck???
2)The driver side window works when it wants to also!!! When is not working if you push the open switch you can hear a click in the door?
Often the problem is the cables that run between the door frame and the door.
These two questions have been discussed here VERY many times.
You can do a search here that will answer your questions.
Type in ‘faulty door lock actuator’ and the other: ‘drivers door window’.
