Thanks for the write up! I tapped mine off of the dome light and have the symptoms Chris had, except mine is the passenger. Turning on passenger map light illuminates all interior domes. Viewing this as a happy surprise, extremely handy at times!
20 posts also seems a bit excessive to me. Long time lurker of these threads, I’ve exhausted every article I can find (here and elsewhere) and now need to post my question. Hopefully I can hit 20 posts without being flagged as spam
