Clicking Sound - Motors

My fan didn't work at all so I replaced the resistor with this device and the fan worked again. The clicks began. I replaced the fan with a new high quality Acdelco fan and it makes the same click. So now I'm going to buy the correct Delco AC resistor part number 1581773 for my Silverado with digital automatic thermostat control.

Pros
  • Pretty impressive
Cons
  • Appearance
