My 2007 Ford transit does not lock?

I've tried guessing which door it is but they all seem to lock then unlock. I read that it could be something to do eoth the rear fog lights as apparently they are on the same circuit as the central locking. I've had the light clusters out and the rigut one has two connectors not connected to anything? Ones a purple on with 6 pin holes with a grey casing and ones orange with two spade connections in a "T" shape. Any ideas?

Hi, My 2007 Ford transit does not lock?

GUESSING? It takes less than 2 minutes to CHECK each door to find out if it is locked.

I don't know it the locks are on the same FUSE as the fog lights, but they ARE NOT on the same circuit. I can say that 'rear fog lights' are not factory installed and shouldn't exist. Any rear lights Can't serve the purpose of fog lights.

Without a wiring diagram, couldn't even guess. You don't say when this happens, with the key, the fob? You could google for a Ford transit owners forum and join one. Someone else may have run into this. I'm 99% sure it has nothing to do with the fog lights.

Usually when door actuators lock and unlock right away one of the door lock actuators is bad. It's the drivers door lock actuator most of the time. It gets the most use.
