I'm getting the same issue, dome light works when turned on at dash light dimmer rheostat, but no by opening door. Door open switches turn on dash door open warning,. So light works, fuse works, door buttons work. Therefore something between the door buttons and dome light is inop. If there is a light around the steering lock key area, this is also not working.
Unsure if this car (CE model, very basic) has a delay dimmer relay for dome/key light. If it does I'm not sure her it is.
If anyone knows a way to easily bypass the relay, if there is one. I would appreciate the info.
