Hi, I replaced the fuse for the central locking as it had been removed and the the door locks just open and close constantly as I connect to the motor. I have changed one micro switch inside the lock and replaced the relay. Any help appreciated

The most common cause of the locks re opening is if one or more lock is not able to shut fully due to an alignment problem.
If you open each door individually and using a screwdriver flick the catch into the fully locked position keeping the door open whilst you do this, then try the central locking, if it works then you have located the problem door lock/catch area. Usually it is a case of adjustment.
NOTE, DO NOT SLAM DOORS WHEN YOU HAVE MOVED THE CATCHES INTO LOCKED POSITION AS YOU WILL KNACKER THE LOCKS !!!!
Instead carefully operate the release handle and check visually that the catch has dropped into the open position and then gently shut the door to test.
You can soon test what I am saying by going to a car with working central locking and leave one door wide open when trying to central lock.:)
 
Hi bugsymike, I have taken the locks out of the car in case there was something stopping it and made sure they are in the lock postion. I have lubricated the locks as well but when I connect the plugs they bonce

I assume the catch was in it's second/fully locked position when testing the mechanism.:)
Is it possible to disconnect one side at a time to test and isolate.
I don't know what age your model is , but earlier vehicles used a separate solenoid to trigger each lock so if that type they could be unconnected physically to check operation, but I suspect yours is a later design.
I had a 2012 Citroen C3 that would lock it's self with the keys in the ignition and the cure was the drivers door lock replacement.
Apart from that I have had Fiat Doblos with wiring faults due to damage at the door hinge area.
