Used Truck HVAC Controls, Flap Actuators & Other A/C & Heating Parts

Used truck HVAC control units, flap actuators & other A/C & heating parts

Not every air conditioning or heating part fits neatly into a single category like condensers, ducts, heaters or A/C hoses. Modern European trucks use a wide range of electronic control units, flap actuators, auxiliary heater components, valves, sensors and small fittings to manage cab temperature and airflow. When any of these parts fails, the result can be a non-working A/C, poor heating performance or constant fault codes on the dashboard.

In this category we list used OEM HVAC control units, flap actuators, auxiliary heater parts and other air conditioning & heating components removed from complete donor vehicles. Typical examples include BHTC/Behr-Hella HVAC control ECUs for DAF XF/CF, flap actuators for MAN TGX and Volvo FH cabs, and Webasto or Eberspächer auxiliary heater components such as fuel dosing pumps and control modules.

What you will find in the Other Air Conditioning & Heating category

Stock in the Other Air Conditioning & Heating category changes as new donor trucks arrive, but it typically includes:

• HVAC cooling control ECUs and A/C control modules that manage blower speed, flap positions and compressor operation;
• HVAC flap / blend / recirculation actuators for temperature mix, air distribution and fresh/recirculated air control;
• auxiliary heater components such as Webasto or Eberspächer fuel dosing pumps, control units and wiring pieces;
• heater control valves and coolant valves that regulate hot coolant flow through the heater matrix;
• A/C sensors and switches including pressure switches, temperature sensors and evaporator sensors;
• small HVAC brackets, mounts and covers that hold electronics or pipes in place inside the cab or engine bay.

Each listing includes clear photos, OE/OEM part numbers where available and donor vehicle details so you can compare connector types, mounting points and part versions with the components fitted to your own truck.

Truck brands & typical applications

Most parts in this category are taken from mainstream European heavy trucks, including:

• DAF XF and CF tractors and rigids, including XF106 Euro 6 models with BHTC/Behr-Hella HVAC control units;
• MAN TGS and TGX long-haul, distribution and construction trucks with electric flap actuators and auxiliary heaters;
• Mercedes-Benz Actros, Antos and Arocs MP3, MP4 and MP5 cabs;
• Volvo FH and FM long-distance and regional haulage trucks;
• other brands such as Scania, Iveco and Renault when suitable donor vehicles are available.

Because these are genuine OEM components removed from complete trucks, each control unit, actuator or valve is normally matched to a specific cab type, HVAC system version and emission standard.

Why HVAC controls, actuators & auxiliary heater parts matter

Small electronic and control components are critical for the overall performance of the A/C and heating system:

• Cab comfort – working flap actuators, valves and sensors allow the system to keep a stable temperature and direct air exactly where the driver needs it;
• Demisting & safety – correctly functioning HVAC controls ensure fast windscreen defrost and demist performance in cold or wet weather;
• System reliability – faulty control units and sensors are a common cause of intermittent A/C operation, fan issues and persistent warning messages;
• Auxiliary heating – reliable auxiliary heater components help reduce engine idling, improve driver comfort overnight and save fuel.

Typical reasons to order from this category

Common reasons to order parts from the Other Air Conditioning & Heating category include:

• fault codes and warning lights related to HVAC control, flap position or A/C pressure sensors;
• stuck or noisy air distribution flaps caused by failed or stripped actuators;
• no temperature change on one side of the cab due to a faulty blend flap motor or heater valve;
• auxiliary heater not starting or shutting down due to a failed dosing pump or control module;
• replacing non-original, modified or damaged parts with the correct OEM components for your truck brand and cab type.

How to choose the correct HVAC control, actuator or heater part

To minimise fitting issues and ensure correct operation, please check the following details before ordering:

• truck brand, model and cab type – for example DAF XF106 Space Cab, MAN TGX Euro 6, Mercedes Actros MP4, Volvo FH4;
• HVAC system version – manual A/C vs automatic climate control can use different control units, sensors and actuators;
• position and function – temperature blend flap, footwell/face/windscreen distribution flap, fresh/recirculation flap, heater valve, auxiliary heater pump, etc.;
• connector type and pin count – compare electrical plugs and wiring with your original part and the product photos;
• mounting style – screw positions, bracket design and shaft interface for flap actuators and valves;
• OEM part numbers printed or stamped on your existing component, matched against the references shown in the product description.

If you are unsure, you can contact us with your VIN or registration number and clear photos of your existing HVAC components and their mounting area. Our team can help you confirm compatibility before you place an order. For general guidance, see How to Find the Right Part and Compatibility & VIN Policy.

Used OEM HVAC components from dismantled trucks

VRA Truckparts specialises in used OEM truck parts sourced from carefully selected donor vehicles. Trucks are inspected and documented before dismantling so that HVAC and interior systems can be assessed. During dismantling, our technicians remove HVAC control units, actuators, auxiliary heater parts and related components, check housings, connectors and moving parts for visible damage and reject units that do not meet our standards.

Usable components are cleaned externally, labelled with OEM references where available and stored under cover in our warehouse ready for dispatch. To learn more about how we work, please visit Our Dismantling & Quality Process, Warranty & Part Condition and Trucks We Dismantle.
