My 2016 Sonic LT has a problem with locking and unlocking the doors. If the doors are closed neither the remote nor the dash/door lock switches will lock or unlock the doors. If the driver's door is open both the remote and the dash controls will lock and unlock the doors. If locked while the driver door is open the driver's door will automatically unlock as it should normally. Is there a module that might control the locking function? Where might it be located?
