Lose the spring out of the fan switch? Use this!
If anyone takes apart their fan switch (heater / A/C fan) be careful not to lose the spring and ball inside. If you're like me, and lose the spring anyways, you can use the spring out of a cheap ball point click pen. Turns out, the diameter is perfect, just cut it down to length and replace. It feels as good as new! I placed the spring into the groove, and cut it flush with the plastic housing. I flipped it around so that the cut end was up against the housing, and the factory end is up against the ball. Way better than buying a new switch!
I was lucky enough to not lose the ball, but it looked real close to the same size as a BB. If you lost that as well, try using a standard BB (for a BB gun).

Yeah you did! LOL I was really careful about not losing the ball, but I didn't think the spring would fall out so easily. I was wrong! With it being so small, it completely vanished into the dash. As soon as I realized it was gone, I knew I would never see it again.
Today I got to thinking about how I could fix it for cheap, then it dawned on me that the spring in a pen is close to the same size. It fit so perfectly you would think it was made for that! It might be me, but I think it feels better than before.
After all that, I found that the switch is fine. I pulled the resistor from under the dash, which was way easier to get to than the switch, and sure enough, it had a broken wire. The real trick is finding a way to fix that on the cheap. I'm thinking of trying a solder job for right now. I can't break it anymore than it already is, and it's easy to swap out when it doesn't work.

The old resistor wire was so dirty and corroded, that the solder didn't want to stick at first. I had to use contact cleaner, a brass brush, and a diamond file to get the wire cleaned up enough to take solder. I'm very surprised that I didn't end up breaking the wires in more places than before. It was a delicate operation.
For the first time since I've owned the truck, the fan works on all four speeds! Now the question is how long will it last. My guess: about 3 days. I will be very happy if it lasts any longer than that!
