Noticed the passenger side map light was not working. Figured the bulb gave it up. Finally had the time to pop the lense off today and discovered that the bulb was still good, but the holder that it sits in had started to melt!! The plastic melted enough to cover one of the contacts, effectively shutting off the bulb.
Anyone ever seen this before? Now, I'm willing to admit possible fault on this... I think the map light probably got left on, but to melt the holder??!! Didn't see THAT coming.
