The overhead lights in my 1976 Sovereign
are original and I am having problems with the 12 v 3 way switch. By turning the knob counter clock wise you cycle through the 3 light options, low, med high. This turns on 2 bulbs, 4 bulbs and the full 6 bulbs. Only the low 2 bulb option works. I can keep turning the knob and sometimes get more bulbs to turn on but it seems the switch is not making good contact as it should. I wonder if this switch is available, any thoughts, thanks.
