To protect the blower motor power circuit, a 20-, 25- or 30-amp fuse is usually located in the fuse panel under the dash. The rating of the fuse will depend on the vehicle application and how much power the blower motor requires at full speed.
Controlling the temperature of the evaporator is one of the most important functions of temperature sensors in air-conditioning systems. The cooler the evaporator, the faster and more efficiently can the passenger compartment be cooled.
If the capacitor is bad, the blower motor may run slowly or inconsistently, or overheat easily. If you notice that your blower motor works strangely or short cycles, make sure to contact professionals to inspect your capacitor.
Blower motors are designed to circulate air, so they won`t work if there`s no air to move. You should always check the filters and vents surrounding the blower to make sure that the blower isn`t having a hard time working.
You might notice that your air conditioner doesn`t turn off when the house reaches the set temperature if you have a faulty sensor, Your AC will just continue to blow cold air. The temperature may even become uncomfortably cold.

Vent Controls: You have four vent control options on the touchscreen, including:
Defrost and lower vents

From what you describe it appears that your vehicle is experiencing some sort of electrical issue. It may be possible that the some sort of wiring problem has occurred, or that the components you replaced are defective. I would carefully inspect the vehicle for any wiring issues, though from what you describe, the unit operating in reverse, it is more likely that the component is defective. It is not uncommon for aftermarket components to be defective out of the box, so if you suspect the component may be defective, I would replace it. A wiring diagram can be sourced from either the dealership, or out of a quality service manual.
If you would like help inspecting the electrical components, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make any repairs as needed.
Anytime you modify any car, there are always details such as this that you will possibly have to address. When you choose to modify a car, you are now the engineer. The simple answer is that I can’t tell you with certainty whether or not the PCM in your car has cruise control capability. The only way to find out is to allow the dealer to check in out. Independent shops might possibly be able to, but the equipment they have is aftermarket and not produced by Mazda. The electronic equipment the dealer has is. The dealer equipment will most likely be able to do what you need.
