I am powering through all manner of service items on my +new+ club sedan. Fixed the opera light sockets. I am a bit perplexed by the wiring for the dome light. What I am wondering is where/how the wiring is routed from the left passenger door switch to the light.
I have an inductive signal tracer and it seems that the ground wire stops above the head liner in front of the B-pillar – that’s where I lose the signal. I removed the rear door sill to access the switch. There is continuity from the switch to the hot side of the dome light, but the resistance is high – about 17 Ohms, so something is fishy there. And… there’s no continuity between the metal case of the dome light and the opera lights or ‘ground’
Thoughts? Guidance? TIA

Can you unscrew the dome light fixture and pull it down enough to access the connections? It may be corrosion of the wire connections or the light sockets. There should be a ground wire to the fixture. There were a couple of comments a few years ago about bad connections to the dome light causing enough heat to char the top wood framing and could have easily led to a fire. If you can’t solve it it may be best to disconnect it.
