OK, I did some trouble shooting of the heater. I have 29V DC at the plug on the RED/Black heater leads. Measuring OHMs I get an open circuit for the heater pad on the other white plug. Opened a case with Heartland and provided answers to all of the question on the Lippert form that Heartland sent me and provided the requested photos. They do not have parts and CS says if Lippert approves it they will ship a whole new right hand seat(seated).
