Citroen Dispatch side door locking problem?

I bought a lovely 06 HDI from Bristol yesterday, only problem is that the side doors will not lock, not with the central locking, not using the key manually or even manually from inside, its like everything is working as you can hear all the clicks ets, but the command is just not reaching the actual lock claw on the door, a freind reckoned it would probably be the rod from the solenoid to the claw, both doors are affected, what do you reckon???
