Interior Light has a life of its own

[abecketts]

Driving back from depositing middle child at Uni and Mrs A was sitting in the passenger seat, she turned towards me and all the interior lights at the front of the far came on. Slightly disconcerting when driving but I wondered why. It seems if she leans on the front passenger door panel when turning it makes the light come on. Would this be another broken earth connection? If so where?

Thanks

I'd check the condition of the door pin in the B pillar?
