I haven't messed with any of the dome buttons since the dome light did come on last evening. So by the above poster's theory, If I don't touch those buttons again, my domelight should come on every time from now on.
Okay, I just went out to my car. It's still dark this morning. I pressed the unlock button once. Nothing. I pressed it again. Nothing. I relocked it. I pressed the unlock button again, and then twice, but a little bit faster this time. The dome light came on. I relocked it. Then I pushed the unlock button again once. The dome light came on.
Seriously, I don't need to be playing musical car-unlock just so that I can get the lights to come on (or not) so that I can feel safe getting inside (or not).
Somebody has to fix this thing. I work too many late nights.
