Looking at the switch

1 2
3
4
5 6

It looks to me like 2 and 6 are the illumination circuit and if measured in situ that would explain the lower voltage

3 is +12V from relay feed for heated seats
1 goes positive in one position (1 and 3 being connected)
4 goes positive in the other position (3 and 4 being connected)
5 is ground use to illuminate the position 1 and 2 lights based on position of switch

and obviously in the central position 3 isn't connected to either 1 or 4
