Ford Repair Questions? Ask a Mechanic for Answers ASAP
i shall post the wiring schematics below for you so you can visualise powerflow as well as help you as you are tracking your wire fault. the bl/rd wire should not have power on it. Instead power flows on the from the fuse ,through the blower motor,through the resistor and then through the selector switch to ground. The BL/Y wire at the blower motor should have power on it as you have , and the BL/R wire should show a ground signal. If the blower does not work and you DO have ground on the BL/R, then the blower motor is bad and will need to be replaced, you can sometimes verify a failed blower motor by tapping it with a hammer, if it tries to start spinning the motor is bad. If there is no ground on the BL/R wire ,then you likely have a bad blower motor resistor, these are fairly common to fail.The blower motor resistor is located on the right side under the dash bolted to the heatercase. The R&R procedure is posted below. Hope this helps
CAUTION: Do not remove the screw in front of the blower resistor. This screw attaches the blower resistor mounting plate to the air distribution plenum. Removal of this screw and the blower resistor attaching screws will allow the plate to fall into the air distribution plenum. Once in the plenum, the plate can be retrieved only by removal of the instrument panel.
no problem at all,glad i was able to assist, you can verify the blower failure by tapping it with a hammer a few times,if it starts turning then the blower is definately bad.just reviewing wiring diagrams and tracing power and ground flow( the load,i.e. blower motor in this case is always the devider point) and checking where the flow stops,will identify the exact location of the fault.
