Door Open Light Staying On, Can't Arm Alarm

[Kinks]

Jumped in my car one day to head home and halfway down the road I notice my door open light is on and the cabin light too. Pull over, check everything 3 times, everything is definitely shut. Happened suddenly, no warning and ever since it's been a continual problem the dash light for the door stays on and so does my cabin light. As a consequence I can't set the alarm, it chirps and complains that a door is open.

It's definitely not the door sensors. I've unplugged both doors and the boot, but the harness side still reads a short circuit or near enough (seems to have about 0.2V on the pins so resistance measurements are off but the meter reports around 30 ohms). So something's dicky. The passenger door, boot and drivers door all do this.

I've poked around at the alarm, even unplugged relays here and there but the interior light stays on. If I unplug the "Smart Entry Control" nissan module then the interior lights go out, BUT I still can't arm the alarm as it does the chirp that tells me a door is open.

Any ideas, before I call the alarm installer during the week?

chase the alarm wiring back through. most of them are found in the drivers sill on a 33. there is also a run of cable going up the A pillars. rip both off and check there.

failing that the cluster also takes the door wiring through it look there as well.

Dont forget the bonnet switch, I have seen some alarms that have only one input trigger (cheap and nasty ones) and it could be connected to the door circuit.
