[7T9BIRD]

When I purchased my 79 T-Bird, I noticed an empty light socket hanging below the dash. The door ajar light didn't work so I put two and two together. I didn't have a bulb at that time, but last year I replaced all the dash lights with LEDs and I realized that the door ajar light will not shut off in ACC and RUN when the door is closed, I looked at the wiring schematic and it looks like a simple diagram with no relays. Power flows from the fuse box to the door switch and then on to the warning light. Everything else associated with the ground works fine as does the dome and courtesy lights. What could cause the current to stay open? Could the ground still be bad?
