why don't the power door lock and trunk release work with the remote or manually on 2003 Mercury Grand Marquis

the power door lock and trunk release don't work with the remote or manually, I changed the battery and still nothing. I checked the fuses and they are not blown.

No they do not. The door locks, inside trunk release button on the door do not work. Also, the doors locks or the trunk release don't work with the remote
