Head scratcher

Some scrote robbed my stereo tother day and in doing so has buggered up some of my electrics.

None of the buttons on the drivers door work apart from boot and fuel release, so am unable to use drivers window or adjust mirrors.

any ideas as my electrician bloke plugged it in to a diagnostic pc and it came up with bugger all other than not being able to communicate with the door control unit.
