Ford Repair: Automatic Climat Control, electronic controller, fan switch

Question
I have a 2001 Taurus SEL with automatic climat control, my quesion is: I had some body work done on the front end of my taurus and now my fan on the climat control will not work.
I had a part # YF3Z-19E624-AA control, replaced on the unit. That worked for 2 days, now it is like there is not enough power going to the blower motor. The fan will come on but at such a low speed, even when I switch it to manual operation and turn the fan switch all the way up. I can feel it blowing, but not like it should.

Is there any wiring in the front end could have been unplug during hood & bumper replacement that has to do with the fan motor?

Answer
There is no wiring or parts in the front that will interfere with the fan control.

Diagnosing this depends on whether you have EATC or manual controls. The manual system uses a blower resistor to control fan speed. EATC uses an electronic controller for fan speed.

I don't know what the part is you replaced by the number.
