Every once in a while, I'll go out in the garage at night and I'll notice that my 2004 Mazda3's interior lights are on. At first, I thought that a door must be slightly ajar so it was holding a switch half way or something like that but that's not the case. The lights will stay on for a while (2-3 minutes perhaps), then dim and go out for a while. Then they'll come back on. The cycle stops after a few repetitions. If I open/close a door, the cycle stops.
Quite a bit of time will go by between times I notice this. I first saw it either late last year or early this year. I bought the car new in Jan 2004. The dealer has never heard of this and could not find any service bulletins about it either. Has anyone seen or heard of this?
Thanks, Stephen
