Heating & Air Conditioning Parts
Discovery 4 heating and air conditioning parts for cabin heating, ventilation, demisting and climate-control repairs, covering heater, blower and refrigerant-side components.
Start with the system and fault being repaired, then check the product page for original part number, vehicle specification, fitting position, pipe or hose connections, electrical connector and any model-year or VIN split before ordering.
Find the right Discovery 4 heating and air conditioning parts
Heating and climate-control repairs divide into cabin airflow, coolant-fed heating, refrigerant circulation and electrical control. Identify which section of the system is affected before comparing individual parts.
| Job | Best place to start | Check before ordering |
|---|---|---|
| Cabin airflow and blower repairs | Blower motors, control modules, resistors, ducts, vents and related fittings | Fitting position, climate-control specification, electrical connector and original part number |
| Heater output and coolant-side repairs | Heater matrices, valves, hoses, pipes, seals and associated connections | Engine, hose layout, pipe connections, fitting position and original component reference |
| Air conditioning compressor repairs | Compressors, mounting parts, drive components, seals and electrical connections | Engine, compressor reference, connector, pipe connections and vehicle production point |
| Condenser and refrigerant circulation repairs | Condensers, receiver-driers, evaporator components, seals and connecting pipework | System layout, connection positions, original part number and any early or later fitment split |
| Air conditioning leak repairs | Refrigerant pipes, flexible hoses, O-rings, seals, valves and pressure sensors | Pipe route, connection size, sensor specification and the reference on the original part |
| Climate-control electrical faults | Temperature sensors, pressure sensors, actuators, switches and control components | Component location, connector, vehicle equipment and original part number |
Check heating and air conditioning fitment before ordering
Discovery 4 heating and climate-control components can differ by vehicle specification, production point and fitting position. Similar-looking pipes, sensors, motors and control parts are not automatically interchangeable.
Confirm the heating and air conditioning equipment fitted to the vehicle, including any separate rear climate equipment.
Separate coolant-fed heater components from compressor, condenser, evaporator and refrigerant pipework parts.
Check front or rear position, left-hand or right-hand fitment, pipe layout, hose connections and electrical plugs.
Use the original reference together with any stated model-year or VIN split before ordering.
Genuine, OEM and aftermarket heating and air conditioning parts
Individual product pages identify the brand or quality level where that information is available. Use the stated brand, part number, vehicle specification, fitting position and connections to compare heating and climate-control components.
| Part type | How it is shown on Twinwoods 4x4 |
|---|---|
| Genuine Land Rover | Genuine parts are identified as Genuine Land Rover where that status is confirmed on the product page. |
| OEM or OE-supplier | OEM and OE-supplier parts are identified where the supplier or product information supports that claim. |
| Aftermarket replacement | Aftermarket parts cover selected replacement and repair components where Genuine or OEM supply is not required or not stated. |
