So... My 99 ford ranger V6 3.0 L 2x4 had an issue with the heat only being on if the fan was on the highest setting. So i looking into it and heard its probably the resistor box. So i thought it was under my dash. I took out this white thing under my dash thinking it was the resistor box, it was actually the diverter to select which fan setting i wanted. So i put it back but no i only have defrost nothing works. i tryed watching the motor work and when i plug it in to watch to see if it moves when i switch settings it doesn't. When i plug it in it just trys to rotate completely one direct. If i dont have all gears in place the motor will just constantly run. Please someone help me?
Heres a picture of what i took out
