The HEAT switch has three settings/positions
The AIR switch has two positions/settings.
Tim,
When you look at the HEAT switch that has the three settings/positions,
How many resistor wire connections are there connected to the back of the switch?
This
PHOTO does not give me a good shot of the resistor and or the back of the switch.
I'm not sure but the fuse might block a clear view to see the resistor wire connections.
Thanks,
