Anyone know what this does? 2 position rocker that says "HYDRN HTR FAN". Its in the center of the dash along with all the other misc. switches such as gen start etc. On a 2009 dutch aire 4085.
Also, if this means anything, the light on the bottom of the switch does not illuminate when flipping it to either position.
Thinking maybe it has to do with the oasis system?
Any input apriciated.
