Lovely.

I have a suspicion that it's a faulty door sensor, since [when it's in one of these paranoid moods] if I have the cabin light switch set to the door-activated position the lights will never go out.

So my question is: what's the cheapest/easiest way to 1) determine if that's the problem 2) fix said problem.

I don't care at all about having a functional alarm system (hey, if somebody's gonna steal the car they're gonna steal the car), but I do need the door locks to still work.

Thanks!
