A/C blower problems
2002 f150 2wd 4.6L Auto trans. My A/C blower would only work on high. No biggie, HIGH was fine I live in Florida. I was going to change the resistor but foolishly never got around to it. Today was a rainy cool day and after driving with it on high for a while I switched it to med-high for a break. Now it won't work on any setting. Should I replace the resistor before I start troubleshooting? What would be the most likely cause?

Took the resistor out and one of the four posts was melted and it burned a hole in the white plastic power adaptor. I checked all 4 Lines no voltage. Where do I find the relay and fuses. There must be more than one fuse in that circuit that could prevent the blower from working. 2002 f150 XLT 4.6
