    Make sure that there is no debris in the air intake or a rodent hasn't made a nest in your air ducts. Ensure the heater housing vent hose that allows moisture created by the evaporator is not blocked and allows moisture to escape and not stay in the heater box. Try spraying disinfectant in air intake allow it to settle for a few minutes, spray the disinfectant in the air ducts in the dash.
