Mystery Switch

I just traded for a 2004 Coachmen Sportscoach 387KS and am still getting acquainted. There is a switch to left of driver seat that I can't figure out what it is for. The switch has a circle with an "M" inside it. Any ideas? Also, is there anyplace on the internet where I can get a diagram of the entire switch panel? Thanks.

    So I wonder if the OP ever figured it out or called Freightliner?

    You are not saying you don't believe the way my coach is plumbed are you?


    ??? I don't see where he said anything about not believing you, I see where he said he hadn't seen that system. Geez...

    FMC coaches all originally had theThermo-San unit. I do know of one owner that added a macerator that discharged at the right rear corner so they do exist!! A later owner removed it.

    Mirror heaters is my guess, but it's also possible it isn't hooked to anything. They sometimes install switches for accessories that never get installed, but the switch is there for future use if you have something you want to hook to it.

    Macerator... So you can let it rip while driving down the road. :B

    Not necessarily a joke. That's actually how my coach was designed when built back in 1988. It has a passenger side macerator discharge for the tanks with a dash mounted control. You just didn't want to be a hitch hiker on the side of the road as this coach drove by!
