1993 Fleetwood Prowler Regal 5th Wheel Trailer

to donn0128 and n7bsn, thank you for your replies. Can't get the hood fan to work. There appears to be an open-short in the brown wire going from the DC fuze panel to the hood fan. I don't know if it feeds to something besides the hood vent fan. Does anyone know if that wire is feeding into anything other than the vent fan?

Also, am presently looking for the RV repair guide by Bob Livingston.
