When my auxiliary fan wouldn't operate, it was the step down resistor...it was cracked and broken from age.

As I have the #14 head, I was always afraid I would overheat the engine.

I removed the resistor from the circuit and used a small bolt and nut to connect the wires, then used shrink wrap tube to seal them.

Now when the pressure goes up on the AC, the fan runs at high speed...no low speed anymore, but who cares...I'm inside the car in the cool!
