Pontiac Repair: Sunfire door lock, 3 doors, actuator

Question
I have a 2000 sunfire and the remote will only open 3 doors all of a sudden will not open drivers side door or trunk?

Answer
if the trunk and the door that wont open with the remote, will unlock fine from the pother manual buttons  , then the connection at or on the body controll module is bad, if the power lock button on the front door wont unlock the non working door then you have a problem with that actuator in the door, if the truck button inside the car will not release the truck then the actuator in the trunk is bad, i hope this helps
