rac said need to find out where the wires from doors terminate any one have ideas

he suspect front fuseboard but without wiring diagram he doesnt know car is 07 reg

Answer in your other post.

Check the BCM which is part of the Fusebox located in the passenger footwell behind the glovebox.

rac guy disconnected blocks on fuse board then reconnected them when we left car 5pm sunday had to leave it unlocked car still no electrics doors still deadlocked

dont know what happened overnight but monday morning started car up display said door shut so reset alarm then unlocked car got back electrics on nearside and doors were able to open 

got autoelectrican coming today fingers x all ok 

 

bad news autoelectrican diagnosed what i suspected bcm knackered 

going to fords this morning to see whats its gonna cost as car too good to scrap

Did you have any luck with Ford?

I was looking through some diagrams for Mondeo of vehicles this age. Assume the electrical system is similar.

From your symptoms I would suspect the Front Passenger Door Module (FDM Front Door Module), which runs on the MS CAN-Bus and also controls the rear door via another Bus. If not the module, the wiring between the A pillar and the module, the BUS wiring is a thin twisted pair of wires which could break over time.

 

go t quote for £1100 to fix would imagine they will do their own diagnostic before they start the work its cheaper than i thought

apparantly the body module is not communicating with body controle module

dont have money to do at moment thinking about px but dont know what worth in condition if could get 1k for car might trade up to x sport

CAN Bus issues are usually broken wires or bad connectors, always easy to blame the large expensive components and its probably the first things that a dealer would change only to find it not that, which that quote would imply.
