I have a 2004 dodge 2500 ram. The fan(heat &ac) blow fine on level 1,2 and 4. Level 3 is less than level 2 but it still works. The fan is quiet with no unusual noises. I thought it was the fan control unit in the dash and I found a used one but it does the same thing with the other unit. Do you think it is the fan unit or the resistor or something else?
Thanks
