1966 Lemans Convertible. Rear courtesy lights in the armrests and the console light only dim when the doors are closed (or when the door switches are manually pushed in) but do not go out. Had to remove the bulbs to prevent battery drain. I’ve removed the door switches, cleaned, removed some paint in door jamb for good ground, even removed + wire in back of alternator to no avail. Grounding issue somewhere, any ideas? Thanks in advance.
