I have a 2002 U320 Model AGDS coach<br/>It has on the kitchen wall a switch with no indication as to what it might be for. It turns on and has a red light on it when on<br/>This Coach does not have insta hot water dispenser, all other switches are accounted for as for there purpose<br/>This is the only switch that has a red light , all the others are with green lights <br/>I hope someone...
