I have an 2002 Taurus SEL with 90K, the DOHC Duratec engine. Recently the alternator went out & I replaced it with a Denso rebuild from Rock Auto. Since the work was completed, something new is occurring, the 3 interior lights (2 front,1 rear) stay on for several minutes after all of the doors are securely closed. (Sometimes they don't go out at all) Thus far it hasn't created a problem with the battery but it IS different from before the alternator went out. Previously the inside lights went out after doors closed, the lights at the base of the mirrors stayed on for a minute or so. I've owned this car for about 3 years now and shortly after I got it, the inside lights would remain on indefinitely, I gave up trying to replace the door switch located INSIDE the door panel. Instead, I ended up lubing REALLY well the latch mechanism and repeatedly opening/closing the door. That freed up the sticking switch. So I'm curious as to why this might be occurring now-About the only thing that I can think of that might account for this issue is I had the passenger side jacked up, but not so the driver's side, so maybe the driver's latch or pillar was tweaked ever so slightly. And yes, I tried spray lube the latch again.
