Let me see if I can make this clearer for you.
I see you change the "Climate Control Module". I assume you meant the Control Head which in this car they refer to it as the Programmer. What you needed to change was the blower motor speed control module which is referred to in this car as the HVAC Power module.

it's located in the engine compartment
