Radio and dome lights stay on with engine off and drivers door is opened

SOURCE: no dome light when passenger door open

Since the passenger door doesn't get used as much as the drivers door, check to see if the switch is not just stuck. It is a little button with a spring that opens up and turns the light on. It is located on the hinge area of the door and when the door closes it shuts off the switch, if it is not stuck then I would suspect said switch.

The door switch needs to be looked at, possibly worn out, check other doors, if they work, then the driver door switch needs to be replaced.

I had the same problem and found that my sliding side door "closed" switch, which is small and round and in the door frame, was not being pushed open all the way when the door was closed! As soon as I put a credit card in the spot where the switch hits the door all the locks and lights worked again. So I just taped a washer to the door where the pin switch hits it for now. The computer thinks the door is still open and will not alow them to lock and the lights won't operate right either.
