Automatic door locks stopped working

All have stopped working with either the remote or the door levers. Do not lock automatically when taken out of Park to drive either.

Test all fuses and then test the drivers door master switch. OR , if your into on-line guesses , skip the diagnosis and replace the master switch, for your symptoms that would be near the top of my list(although I prefer testing and proof). Keep in mind , that the others follow what the DRIVERS DOOR LOCK ACTUATOR does , so if it is not working , the others won't act properly either. Good luck.
