I have a 99 Monaco Windsor with a 330 Cummins, side radiator. Dash heater is not blowing any air IF there is any heat. Is there a fuse for the fan if and if so, where is it located? HELP. Jim
Are you sure it is not blowing air check to see if air is coming out the defroster vents? If so it most likely is the vacuum vent door that is not working The vent door goes to defroster vents when vacuum is lost.
