my son owns a 2000 ford Focus SE model that is the Sony edition. The issue is that late this summer the blower fan quit working altogether. It does not work on any setting speed. It does not work on the A/C setting either. Here is what I have done
so far: 1. I replaced the blower resister 2. Replaced the fan speed switch in the dash. Neither part solved the problem. I know there is power to the blower switch that I replaced in the dash, because when the defroster is selected, and you turn up the switch
speed I see the A/C light turn on, which tells me the switch works. When I replaced the fan switch in the dash, the plastic switch connector block that plugs into the back of the switch showed the plastic housing partly melted. The interesting thing about
that though is that the inside of the housing of the switch, where the wire block plugs in was not melted. I wonder if whoever owned the car before my son had already replaced the switch once before indicating there was an issue before. Regardless I need to
figure out what is going on and why it isn't working. It is cold now here in Idaho and he needs heat and a defroster. I think I checked the correct fuse under the hood for the blower motor
to see, maybe it checked the wrong fuse, or there is another fuse that
went out that would control something else that would not be supplying power, I don't know. What do you think?
