Good morning and I'm hopeful you may be able to guide me to an answer. I have a 97 American dream and I am having a really tough time turning on the block heater. I have the block heater plugged in, but I hear there is a switch somewhere that will activate the block heater. The patio receptacle breaker and all breakers are turned on but it is this mysterious switch that I am unable to fine. Any direction you may be able to provide, I would be very grateful. Thanks, Brian
