A/C Fan Issue

[WhiteSnake99]

I am trying to order the part to fix the issue but cannot for the life of me remember the name of it. Its the circuit board that controls the fan speed usually located by the fan itself. If anyone can help I would appreciate it.

Thank you. The name just wouldn't come to me even though I have replaced a few of them.
