Discovery dash heater fan blower will not come on

[bland]

I have a 97 Fleetwood discovery, my dash heater fan blower will not come on. I have checked the heater fuse in front of the coach in that panel it,s good. I am told there are 2 inline fuses under the dash near the blower motor. how do I get to them? I have removed the carpet on the passenger side but cannot figure out how to remove the panel. I don,t have internet so call at 919-330-7559 thanks benny

Cant call except via ham radio but try this drastic test find a 12 volt power supply, connect to the 2 wires directly from the fan. If fan works the problem is between the fan motor and switch...trace the wires and find the problem. Also you can try 12 v and ground across the switch. Do you have 12 volts across the switch?
