Door ajar sensor on transit crew cab mk7??

[Starscream]

Hi, my 07 transit has its door ajar light on all the time. When I lock it the horn sounds but all the doors are locked?! I know which door it is as it's slowly been playing up and now nothing. My question is, does anyone know where the sensors are?? I've had the door apart not really knowing what I'm looking for to be fair so need to ask the hive mind. Cheers

It might work off the interior light switch?

How do you mean? I have turned the light off manually because it stays on

Interior light stayed on probably because the door switch is u/s and shorted to earth or the wire is earthing out due to rubbing through insulation somewhere

[Commando]

Quite often the alarm utilises the interior light door switch as a sensor, see if you can pick up a replacement from a scrappy?  Its a cheap try that might fix the problem?

I think htb is on the money. Same thing happened with my mates 09 plate Transit. Light stayed on, horn beeped. A new switch sorted it.

My 62 plate transit is doing the same thing, we know which door it is the one which doesn't lock on central locking. My mechanic mate reckons the wires have worn in the and broken in the hinge area.
