Ford Repair Questions? Ask a Mechanic for Answers ASAP
Squire51, I have read your question and refered to the the climate control wiring diagram for the 2000 Focus. By the diagram it appears you have an open circuit in the low speed resistor of your blower resistor block. Follow these pinpoint test and it should direct you to the proper repair. I can not perform these test without the vehicle,but they are pretty straight forward and should help. If so please accept my answer and leave positve feedback .If not let me know and we will continue to work together to achieve the proper answer. Thanks,Al

Some 2000-2003 Focus vehicles may exhibit water in the Climate Control Heater Blower Motor Case, which can be associated with an inoperable heater blower motor resistor, blower motor, or a blown blower motor fuse.
Inspect and seal the cowl area for water leaks when servicing a blower motor resistor, blower motor, or a blown blower motor fuse. Refer to the following Service Procedure.
