The last couple of days I've noticed that ALL interior lights are on all the time whilst driving, pushing the switch buttons makes no difference, so I wondered if a door wasn't closed properly, but all were shut, also, I couldn't see any 'door-switches', & I wonder just where the lights get the switch
commands from??

When I leave the car, lights still on, but the all go out a few seconds after locking.

Any ideas? Am I missing something??
