No. Afterblow is controlled by the car computer talking to the AC computer, telling it to keep the fan running for a while after key-off. No extra hardware.
What concerns me with yours is that you have a second failure of the fan controller. Do you know what was replaced when it was previously repaired? Do you have the receipt?
If the fan speed controller had died and was replaced, but the fan motor was not replaced, I am wondering if maybe there's some quirk with the motor whereby it presents a load to the speed controller that damages the speed controller. This is analogous to the speaker frying the amp, but, in the case of motors, it's not out of the question.
If you can find your old receipt, and it shows they didn't replace the motor, you might be able to argue that they should have done that when they replaced the speed controller and hence that they should cover this.
But that might be a hard case to make.
