Here's a wierd one... dome lights only work with key in run position. door switches are fine. opening the doors or using the headlight dimmer no dome lights, or map lights. turn the key to run and all the lights work. and the other electrical gremlin, no power to radio on wire on always hot circuit. fuse good no power to fuse (i'm going to check connectors under fuse panel later today)

 

Hiya,

I have that same issue actually (98 grand voyager), tried to figure out if the settings were right as I don't have a manual with the car. Have never managed to get courtesy lights to come on with doors opening and like you say switches are fine as are lights as they all work when engine is running. Thought it was me but never really paid too much attention to it. If you find the reasons for this I would be grateful if you let me know.

Good luck.
Robert.

 

sounds like a BCM and or junction block the M1 ckt that u are talking about comes from the BCM itself done and power door looks are also from the bcm.
