I have a 2003 sport trac my blower speed works on low and high just fine but number 2 and 3 speeds blow at the same just a little more than low. I have replaced the resistor, resistor pigtail, the switch and still the same. I unplugged connector and used a jumper wire to bypass resistor this did not work. Next I checked the continuity between the switch connector and the resistor connector this was fine. Could anyone help me out with this problem????
