Glad to hear you got it fixed. I always bring my voltage meter with me to the junk yard. Mainly because the resistors are like 40-60 bucks new at Ford, so I just go pick em out of a junkyard.
Also you can take them from any make or model along the years of 00 to 04 range, The Zetec, Duratec, and SPI all use the same resistor packs. Just the Duratec's will have them at the bottom of the fan set-up.
