Topic (blower motor) i recently discovered that my blower motor stopped working so i took it out and hard wired it straight to the battery and it seemed to be working fine, so then i check for continuity on each individual terminal on the back of the switch , it also seemed to be working just fine , then i decided to check the relay and fuse but there is no visible indication on the cover for the relays or fuses, so where will i find out how to get that info ?
I have the same problem. My heater fan was working and when the outdoor ambient temp drops the fan will not work. I replaced the fan switch, relay, and don't have any power at the fan or switch.
Does anyone have a clue where to start?

To be honest with you I hate the way Ford has decided to make fuse and relay identification so difficult. The imprint on the covers say "refer to owner's manual", but if you don't have one then you will have to invest in a DIY repair manual. You can typically purchase these at most auto parts stores. You could also check your local library. There are online services that you have to buy a subscription to use. Try Chiltons, Haynes, All Data, online services. Hope this helps.

The burnt wire's ,are they in the connector that plug's to the control switch ? High resistance ,loose fit cause's this . If the motor works on high the switch isn't the problem , The blower motor resistor is . On high the power flow bypasses the blower motor resistor to ground . Do you know what a blower motor resistor is ? The switch just supply's a path to ground through the different resistances to create different speeds. Your switch probably is not bad . But rather then guess use a ohm meter an test it. Do you know what a wiring diagram is ?

if power was going to earth ..the fuse or relay would blow ..blower motor would spin if it blows the fan fuse or relay something is wrong with the on /off switch for the blower picture is the 2003 heater system
if no better make up a new earth wire to chassis for the blower motor
Blower motor resistor needs replacing. Follow wires from blower motor to connector, which should be the resistor. Usually in duct work, held in by 2 small screws.
My rear blower motor stopped working and my Brother took the unit apart. He found out that the fan blade had seized up the unit. After he took out blade and sanded down blades, it worked fine. However, I am not sure about your front unit. Good luck.
