hey all thought some of u could shed some light on my problem

the problem i have is this central locking stuffed up on me and was going up and down up and down like crazy now it has stopped so i tried locking it wit the remote and all it does is bip the horn at me exterior lights work but does not lock
i pulled the drivers side actuator out and it was cactus getting a new one but before i install that i have another problem
the back doors have stayed locked open from the inside but not from the outside the passenger front door doesn lock but can lock the drivers door with key ( note the drivers door actuator is out of the car ) my tailgate actuator is also opening and closing but wen u unlock it and go to open the tail gate wit the handle it automaticlly locks again
can anyone shed any light on my problem ? thanks in advance
(also note that the button inside on the dash does nothing )
