Default Ac problems

Can you guys plz explain to me what these plugs are and what they do, the second photo is a relay im pretty sure and the previous owner had it rigged to be connected to the first plug in a weird way to where it wasnt plugged into where its plugged into now but just pulled out and a wire stuck into the plug to the relay is how it was. Trying to get this ac working idk what alls wrong with it just trying to isolate the problem here.

Those plugs are plugged into the Blower Control Module which electronically controls the speed of your blower motor.

The red wire is 12v powwer, the other 4way is the ground and blower speed control and if i remember right the purple is blower motor 12v supply. The fsm has specific instructions on how to test the system if needed.
