Tuesday morning, mine only worked on high. Went to Ford dealer, spent 13 bucks on the resistor, took 5 minutes to replace it in the parking lot outside the office, now I have all 4 speeds again. I knew to do this because of the great information available on this site as in the linky in one of the previous posts. This is a GREAT site.
