"HYDRN HTR FAN" switch?

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.Click image for larger version

Apparently in controls a fan/heat exchanger for the front of the coach. Check out the following thread...

"Caleb1".....Take a minute to read the Oasis for Newbies link that I left in your last post/ It' about a three or four minute read and it answers all these Oasis questions and more.

Thanks for the responses. This makes sense. I was previously unaware of there being an oasis radiator under the dash, but now this makes more sense.
Thanks.
And I read your post don and it explains the oasis nicely.
