I have 2 2012 Blue bird all Americans with rear cummins engines . Both have front heaters that won't work on low . These heaters sit back behind the driver a few seats back . The switch is good . I have power . Could the motor be bad . I am not sure if these are computer controlled so I need some education with these . I just find it odd two of the same buses with the same problem ? Thanks
