My fan motor quit working.... then it works... and it quits... i pulled the dash and there is no power at the switch for the fan

If it's the only window that isn't working it has nothing to do with the fuses. You do not have a separate fuse for each window. If the power window fuse was removed and not placed back into the correct slot, all of your windows would not work. I would start at the window switch and see if you have power to the switch, then move on down the circuit to find the issue. If you end up with the motor getting power when you activate the switch, but nothing happens replace the motor.

Yes dash control is bad most likely

Most of the time when a heater blower quits working it is the blower switch that fails rather than the motor. Blower switch can be accessed in the dash panel.

yes and it possibly could be the motor to check you need test equipment for starters a volty ohmn meter to see if your getting power to the motor and a continuity checker for the switch to see taht it is working properly

check the fan switch in the dash and the fan motor connector for burning, if u find burned connectors replace them and the heater blower switch.

If it only works on Hi, then your resistor is blown. If you can pull the connector to the blower fan and use a voltage tester to find voltage there with the fan switch turned on then it's the blower motor. If there is no voltage there, then its the switch on the dash. Usually the resistor and the switch only die because the blower motor is about to die and is pulling more current then it's supposed to. Change the blower motor too if that's the case.

Usualy the electrical problems are not due to wires if the fuse did not burn out. More often it would be a bad fan motor or fan switch. If you have an electrical testor find out if there is power going to the motor by placing the testor leads on both sides of the switch when it is on. This may require you to take the dash appart a little. Or you can short circuit the switch by puting a small wire accross the leads to the switch in order to bipas it. If the fan turns on the motor works and the switch is bad. If you are ok with taking part of the dash appart then you can always attach a battery with leads to the motor directly to see if it works.

The switch in the dash is known to go bad commonly in 01-04 Fords

Check it with a test light or Multimeter for power to blower motor first, with switch on high. If no power to motor, problem is elsewhere. Here's a link that will help you. Click on the pictures to expand.

dash yes book time is 6.5 hours..ouch... check blower motor resistor first..and blower relay... the usual suspects here
