With the heater on high (setting 5), the fan stopped blowing heat. I then set the blower to setting 4, and the fan worked fine. As soon as I then put the fan back to 5, I would hear a click but the fan would not work at all. I then began to fiddle around with the connector that is under the passenger side dash which powers the fan. If I move the one wire around, the fan would intermittently work while on setting 5. I unplugged this connector from the blower motor, noticed that the one wire seems as if it was causing a short (the wire was somewhat black from over current). I removed the pin from the connector, recrimped and soldered it. Worked fine until a few weeks ago when the fan once again began to stop only on setting 5. I am assuming that the problem is once again the connector that goes to the blower motor powering the fan resistor. I saw a few reports of this on here about vehicle fires all of which point to this connection being bad. So I thought I would submit this as well due to the vast amount of issues I have had with this truck.
