Are you looking for a reliable resource to help you understand the AC wiring diagram of your Ford Fusion? Look no further. In this article, we will provide a detailed and easy-to-understand guide to help you comprehend the wiring diagram of your car’s AC system. We will also answer some common questions related to the topic. So, let’s get started.
Understanding the AC System of Ford Fusion
Before we dive deep into the wiring diagram, let’s briefly understand how the AC system works in your Ford Fusion. The AC system comprises several components, including the compressor, condenser, evaporator, expansion valve, and refrigerant. The compressor pressurizes the refrigerant, and then it flows through the condenser, where it releases heat. The refrigerant then flows through the evaporator, where it absorbs heat and cools down the cabin air. Finally, the refrigerant flows back to the compressor, and the cycle continues.
The AC system of your Ford Fusion is controlled by an AC clutch cycling switch and an AC pressure switch. The AC clutch cycling switch turns on and off the compressor, while the AC pressure switch measures the pressure in the AC system and turns off the compressor if it exceeds the safe limit.
The AC Wiring Diagram of Ford Fusion
The AC wiring diagram of your Ford Fusion is a schematic representation of the AC system’s electrical components and their connections. It shows the location of relays, fuses, switches, and wires in the AC system. The AC wiring diagram is essential for troubleshooting electrical issues in the AC system, installing aftermarket components, or upgrading the system.
The AC wiring diagram of your Ford Fusion consists of several components, including the AC clutch cycling switch, AC pressure switch, compressor clutch relay, cooling fan relay, blower motor relay, AC control module, and several fuses.
AC Clutch Cycling Switch
The AC clutch cycling switch is located on the high-pressure line between the compressor and the condenser. It turns on the compressor and controls its operation based on the temperature of the evaporator. When the evaporator temperature rises above a certain level, the switch turns on the compressor. When the temperature drops below a certain level, the switch turns off the compressor.
The AC clutch cycling switch is connected to the AC control module through a green with white stripe wire (Pin 12).
AC Pressure Switch
The AC pressure switch is located on the low-pressure line between the evaporator and the compressor. It measures the pressure in the AC system and turns off the compressor if the pressure exceeds the safe limit. The AC pressure switch is connected to the AC control module through a red with white stripe wire (Pin 10).
Compressor Clutch Relay
The compressor clutch relay is located in the engine compartment fuse box. It controls the operation of the compressor by applying power to the clutch coil. The compressor clutch relay is connected to the AC control module through a dark green with yellow stripe wire (Pin 8).
Cooling Fan Relay
The cooling fan relay is located in the engine compartment fuse box. It controls the operation of the cooling fan, which cools down the condenser. The cooling fan relay is connected to the AC control module through a dark green with red stripe wire (Pin 14).
Blower Motor Relay
The blower motor relay is located in the passenger compartment fuse box. It controls the operation of the blower motor, which circulates the cool air inside the cabin. The blower motor relay is connected to the AC control module through a white with pink stripe wire (Pin 2).
AC Control Module
The AC control module is located in the passenger compartment fuse box. It controls the operation of the AC system by receiving signals from the AC pressure switch, AC clutch cycling switch, and temperature sensor. It also sends signals to the compressor clutch relay, cooling fan relay, and blower motor relay to control their operation.
The AC control module is connected to several fuses, including F2.15 (10A), F2.18 (10A), F2.19 (10A), F55 (7.5A), and F58 (7.5A).
