Looking for ideas as a fix for this seems expensive. My map lights on the overhead console stopped working, both when the door opens or by the push-up switch. I replaced the bulbs with no luck. It's not the fuse--and the weird little "shifter light" in the middle still works. All other interior lights work fine.
I pulled the overhead console and removed the bulb socket assembly and checked for voltage. It's a strange socket connector--removes with a quarter turn and then the voltage is delivered by two thin strips on a circuit board. I couldn't get any reading there (maybe I was doing it wrong?).
Anyway, it seems the only part I can replace is the entire overhead console assembly (minus the off-road dials), which is over $900! Here is the part:
