Blower motor not consistent
My heater/Air conditioner blower has always blown intermittently, and at varying speeds. 3 days ago the blower stoped working altogether. I can still feel heat from the vents, but is not blowing out and causes quite a problem in the morning when the windows are foggy, will not defrost.
