Yes it was completely corroded. The protective metal 'cover' of the resistor (with all the holes in it) just crumbled to pieces as soon as I began to remove it. The funny part was that even though the fans did not operate in low speed everything else worked - AC, no overheating, etc. I only discovered it because I was suspicious that I was not getting both fan speeds and was doing the relay bypass test so I could test/hear them. Once I replaced the resistor and the low speed fans operated I noticed my AC worked much better because it was now cooling the condenser as it should.Oh my! I've seen those corroded fan resistors before. Seems to be related to living in the rust belt areas. Chemicals on the roads cause it.
