Mk7 Transit and the interior light in cargo bay is permanently ON.
So it thinks that either the side door or rear door is open and wont lock the van (horn beeps), I thought it was the little plunger switch on side door so I unplugged it but made no difference.
Im assuming that the switch is normally closed so that when the door is open it switches a wire to ground, so unplugging should turn the light out - can anyone confirm if thats correct please?
Ive pulled out wiring loom to side door but can find nothing wrong.
Is the interior light on a relay - if so which one and where is it?
Is the back door ajar switch part of the lock mechanism?
Help and advice appreciated as always
