Iminaccess,
That light just means your coach heat is in the heat mode. If you turn down the rheostat on the panel to the driver's left, the light should go out. When you turn it clockwise to a higher temperature setting the light will come on. To turn the heat off in the driver's area, turn the valve handle under the panel to the vertical position. You'll find the info in the owner's manual. If you don't have that and a maintenance manual, you need to find them. There are both a big help. If you have other questions, don't hesitate to ask here. I just hope you can come up with a dumb question that hasn't been asked, because most of them have already been asked here; some of 'em by me!
Good luck,
Dennis
