The problem with my 2006 Ford Focus looks like a heater blower motor problem. But I am not sure.
I have a regular turn-the-knob type of heater/AC not the electronic type. The blower speed setting has 4 steps, and it does not function on the lowest setting 1, but 2, 3 and 4 work fine. I thought the blower motor resistor is faulty when it blows at the highest setting or does not blow at all. With mine, only the lowest setting is not working and the rest are fine. Is this also a blower motor resistor problem?
Thank you in advance for answering my question.
