Let me check it out again. I know I got low fan when I accidentally grounded one of the wires coming out of the high temperature switch. I held it there for a minute, but then I noticed some glowing and sparks from the aux preresistor (where the single wire attaches on top), so I terminated the experiment.

I'm getting ready to hard wire the high fans to work anytime the ignition's on and just have a switch for the winter months where I can go back to normal.
