Recently I had my front passanger window fail on a 2005 Mazda 3. So the mechanic I used come and took the door panel off and replaced the motor and actuator thing. OK great, but since it was done the cars central locking would no longer work as the dash displays that there is a door open. I have obviously gone around the whole car making sure that all doors are closed.
So now I can't use my central locking. I have pulled the fuse out for the central locking and now have to manually lock each door individually to be able to lock my car. But the dash still displays that the door is open and the interior lights come on if left on the switch on when doors are open setting.

So what does everyone think the problem is here? I have been unable to contact the mechanic again.

Many thanks
