Heater operation in my 39

Val

I think maybe this is the control switch for the heater in my 39. Not sure though. It reads S=F indirect on one side and F-S direct on the other. Not sure what that means. Any help is greatly appreciated

Just going to take a guess here but I would say the letters F and S stand for fast and slow pertaining to the speed of the blower fan. Indirect I would think is the direction of air to the defrosters, and direct would be to the cabin heat. The switch is different than on my 39. I have to manually switch the air flow from defroster to cabin at the heater, the switch just controls the fan speed. Hope this is of some help. Let us know what you find out.
