Hi sheryl,
Did you find the fuse for the a/c heater? What kind of chassis do you have? If the fuse is good go to the connector on the blower motor and test for voltage at the postive connector with a test light. If you have voltage tap the blower motor with a small hammer or wrench. The brushes or contact could be stuck. If there is no voltage you will have to start tracing back through the wiring system, relays, switch, resistor or opens for the problem. If the fuse is blown it had a reason such as short or blower motor drawing to many amps. Hard to say unless someone else has had this problem on a Newmar. Wiring diagram would be very useful in locating these kind of problems. Good luck and let us know what you find.

Definetly not an easy task trying to find if its a short
or fuse or relay or blower etc.
Nice to know people are eager to help with advise on this forum.
