Ah, good to know! So somewhere else. I'm pretty new at working on cars and understand some of the basics, but am not skilled in any way. Is there a place that you, Bigshankhank or anyone else suggest checking first? A connection particularly prone to becoming loose or failing? Not sure if it would be related, but my door ajar buzzer sometimes works and stays on as long as the door is open, but other times it starts then cuts off/is intermittent. Everything else seems to work fine (power windows, power locks, interior lights, etc).
