So my blower resistor failed again, and the fun thing about it is that it always fails in different ways. Once I lost the high speed. Another time I lost everything but high speed, and this time I lost all speeds. So I got a replacement and it worked, but becauseI tested it out before screwing it in I was able to see how hot it got. The wires leading to it were hot inches away, and eventually it started putting out a burnt plastic smell which led to smoke.
I took it back and got another, and this one gets the wires hot several inches from the resistor. I know these trucks eat these things, but is this beyond the abnormal for these trucks?
I also dropped the fan and it was half full of leaves!
It was probably a mistake but I put dielectric grease on the old resistor and that stuff seems to have gunked up in it. Anyway to clean out a molex plug?
