When the door is open, the inside light plus the light at the bottom of that door should come on. They do not. The same on the other door. The inside light does not work via the toggle switch either. The bulbs are all good and the fuse is also good. I proved this by removing the light cluster and bridging the contacts on the back of the switch. The 3 lights come on even though the door is then closed.
