This Ion belongs to a young man I know. He asked me what was wrong wit it. I’d suspect it has something to do with the door latches or door light switches. I know that’s a common issue on Tauruses, but I can count the number of times I’ve been in a Saturn on one hand. Neither if us is close the car for an easy look-see. Are the door light switches in the latch like a Taurus. If so, is the fix the same, spraying some electrical contact cleaner into the latch to clean the switch? If not what do you think it is? ---

Far from a silver bullet, but I have seen a number of Saturns that had unexplained warning lights/chimes, erratic interior lighting, erratic or no instrument cluster operation, door locks either inop or operating on their own, etc. All turned out to be faulty Body Control Modules. If I recall the courtesy light switches are plunger switches on the jamb. ---

The BCM controls it all. I would check the battery condition and battery terminals and grounds before replacing it. ---

There’s a lot more to check and test other than battery terminals and grounds, and you won’t be able to check those things without a decent scan tool. You’ll also need a scan tool to replace the BCM. But we don’t know yet if the BCM is even the problem. ---

He’s not going to like that answer, but I’ll tell him tomorrow. It’s his last Sunday as a summer intern at my church.
