Ford CD345 2006 Technical Manual – Factory Specs for HVAC and Electrical Systems

If you have ever been stuck mid-diagnosis on a Ford CD345 because the aftermarket manual skipped the stepper motor positions or gave you a torque value that didn’t match any bolt on the car, you know the waste of time I am talking about. I have torqued more head bolts than most people have had hot meals, and I will tell you straight: the only thing that saves a comeback is factory data. This is the Ford CD345 2006 Technical Manual – 51 pages, original OEM print from Ford, covering the electrical system and the HVAC setup. No reprint, no third-party guesswork. You get the same document the dealer techs used.

Electrical System Coverage: What You Get

The manual opens with the electrical system (page 1 labels it HỆ THỐNG ĐIỆN). That section covers the control modules, wiring logic, and component locations. You are not getting a full wiring diagram booklet here – this is a technical manual focused on system operation and diagnostics. For a full harness drawing, you will want the Ford CD340 CD345 2010 Wiring Diagram. But for understanding how the HVAC control unit talks to the stepper motors and the blower controller, this manual lays it out component by component. The charge pressure specs? They are not listed on a sticker under the hood – they are in the factory service information. That is where this manual matters.

HVAC System: Stepper Motors, Sensors, and Duct Routing

Starting on page 3, the manual breaks down the air conditioning and heater system. You get exploded views of the air distribution housing: the recirculation stepper motor, the right and left temperature blend door actuators, the center vent temperature sensor, the footwell sensor, the optional air quality sensor. The duct routing on page 5 shows the six outlets – center, defrost, footwell for front and rear, and the B-pillar vents for rear passengers. When a customer complains that the left side blows cold but the right side blows hot, you can trace the fault to a stuck blend door actuator. The manual gives you the motor part numbers and the control logic. No substitute.

Does This Manual Cover the Fuel System?

No. This Technical Manual is dedicated to the electrical system (page 1) and the HVAC system (pages 2–5 and beyond). If you need engine management, transmission, or chassis data, look at the Ford Mondeo 2003 Technical Manual – OEM Factory Data – the CD345 platform shares a lot with the Mondeo. For suspension and multibody dynamics, the Ford FALCON Technical Manual – Multibody Vehicle Dynamics is a different document. Keep each manual for its job.

Source Authenticity: OEM vs Aftermarket

I have seen aftermarket manuals that call the refrigerant charge “approx 24 oz” – that is not a spec, that is a suggestion. This manual came from Ford. It was printed January 2006, marked “Ford Secret” (internal use). The torque values for the HVAC housing screws, the expansion valve installation, the blower motor retaining bolts – they are in inch-pounds, not guesses. You can trust the page because the document came from the manufacturer. If you want to see how the Automotive Industry Overview handles documentation standards, compare any aftermarket PDF to this. There is no comparison.

Who Needs This Manual? Techs and Owners

If you are a shop tech who sees CD345 vehicles – they were sold as the Ford Mondeo, Ford Fusion (global), and Lincoln MKZ – you need this for HVAC diag alone. Home garage owners: if your 2006 CD345 has an A/C that blows warm on one side or the recirculation door clicks but does not move, this manual saves you from buying a whole HVAC case. It lists the 11 components on the evaporator/heater unit (page 3–4) and the 6 duct sections (page 5). You can pinpoint which stepper motor to replace instead of shotgunning parts. That is time and money.

Is this manual in English?

The manual is in Vietnamese.

Does it include wiring diagrams for the entire car?

It covers the electrical system architecture and component locations, but it does not contain full-color connector pinout diagrams. For harness-level wiring, the Ford CD340 CD345 2010 Wiring Diagram is the document you need. This Technical Manual focuses on system function and diagnostics – what each stepper motor does, how the air quality sensor feeds the controller, and the airflow path. If you are chasing a short in the rear lighting circuit, this is not the right tool. But for HVAC and basic electrical system understanding, it is the factory reference.

You do not have to chase ghosts with a 20-year-old car. Get the document that Ford gave its own technicians. Automotive Industry Overview might tell you about trends, but this manual tells you the exact location of the left temperature blend door motor. Access the Factory Manual.
