Hi, I have a problem with the central locking on my wifes zx. If i lock the car on the drivers door all the locks lock. I i try to open the drivers door all the locks open. Now if i do the same on the passenger door opposite, the central locking goes up and down about four times and the central locking stops working untill i open the drivers door. This is affecting the alarm that is installed as the alarm locks all the doors when armed but because this door plays up the locks arent locking. Does anyone have any ideas as to what could be the problem and if its an easy mend or would a new actuator be advised? thanks for your help Ed
