Friday morning I ran our 2001 Impala to warm up the engine to defrost the windows and the cabin lights (one above each of the back doors, and two on the bottom of the center rear view mirror) all would not come on when I opened the door or when I tried to turn them on with the headlight/cabinlight switch. I ran the engine for a while, while I cleared off the snow and ice from all the windows. When I opened the door to get back in the cabin lights came on (except for the one above the back passengers door which must be burned out). After I closed the door and the cabin lights went out I tried the headlight/cabinlight switch and the cabin light would come on when I selected them.
What could be going bad that caused the cabin lights to temporally not work?
