Land Rover Heating & Air Conditioning

What do Land Rover heating and air conditioning parts cover?

This collection covers the cabin heater, the blower and its controls, the vents and ducts, and the air conditioning circuit for Land Rover and Range Rover models. It is one of the subcategories of Land Rover Cooling & Heating Parts.

Parts here are listed for the Land Rover Series, Land Rover Defender, Land Rover Discovery, Land Rover Freelander and Range Rover families, including the Classic Defender. For older models covered by the catalogues, use the Land Rover parts catalogues to help identify the correct part number before ordering.

The Defender 300Tdi workshop manual describes a heater assembly made up of a heater matrix in a distribution unit and a variable speed blower motor, attached to the fascia bulkhead, with the matrix connected to the engine cooling system. It lists the air conditioning system as four major units: an evaporator matrix and expansion valve in the heater/cooler unit, an engine-mounted compressor, a condenser in front of the radiator and a receiver/drier, connected by preformed metal and flexible refrigerant pipes.

Most heater hoses are in Land Rover Coolant & Radiator Hoses, and most heater control cables are in Land Rover Mechanical Control Cables. Other Cooling & Heating collections cover Land Rover Radiators, Intercoolers & Tanks, Land Rover Water Pumps, Thermostats & Fans and Land Rover Oil Coolers, Pipes & Hoses.

Land Rover heater matrices, heater valves and heater units

Some heater matrix titles state the variant, such as pipe layout, output, drive side or A/C use; others give it only in the listing description, so read both before ordering.

• Heater matrices. Classic Defender matrices, including an aluminium high-output matrix, a high-output matrix with straight pipes, a matrix with downward-facing pipes and matrices titled LHD or LHD/RHD. A Series matrix and matrices for the Discovery, Freelander and Range Rover are also listed, including a Discovery and Range Rover matrix titled 300Tdi A/C.
• Heater valves. A cable-controlled heater control valve, a T-piece heater valve, a heater valve listed with or without its bracket, and a heater water valve.
• Heater pipes and manifolds. Heater pipes, including a 300Tdi heater pipe and a heater pipe kit titled Air Con, a heater return pipe, and heater manifolds titled for the 3.0 V6 and 5.0 V8.
• Heater units. Heater assemblies, including one titled Diesel and an LHD heater assembly for manual A/C. A high-voltage PHEV water heater is also listed.

Many matrices carry no model or engine in the title, so confirm the part number against your vehicle.

Heater blower motors and blower resistors

Blower motors are listed, some titled as motor and fan, and many titles state LHD or RHD. Read the listing description for what is supplied. Blower resistors are listed separately as resistor packs, a resistor kit and resistor control units, including a blower speed resistor for vehicles with A/C. Blower motor and heater wiring harnesses and a heater motor adaptor lead are also listed.

One blower motor title gives a VIN break, from (V) YA256944. Where a title or listing shows a VIN, compare it with your own before ordering.

Heater controls, vents and ducts, including Classic Defender and Series parts

Heater controls and control assemblies are listed, including LHD, RHD and cable-type versions, together with an air conditioning control assembly and a heater and air conditioning control unit. Knobs, finger grips, a control label, a fan label, a mounting plate and a control pin are listed as separate parts, alongside a heater blend motor and blend stepper motors.

Vents and ducts include a dash vent louvre, facia louvre vent housings, a vent louvre bezel, air vent controls and an air vent mechanism, vent knobs, LH and RH heater ducts, heater deflectors, a demister kit for the windscreen and side windows, a demister tube and a demister hose, and heater-to-bulkhead seals for LHD and RHD.

Land Rover air conditioning parts for Defender, Discovery, Range Rover and Freelander

Compressors are listed by engine where the title names one, including the 300Tdi, Td4, 1.8 K Series, 2.5 KV6, 2.2 diesel, 2.7 V6, 3.0 V6 diesel, 4.0 V6 petrol and V8, and some are listed with the clutch or as a kit. Condensers are listed by engine or position where the title names one, with condenser fan assemblies and a condenser kit.

Evaporators, expansion valves and receiver driers are listed separately, as are A/C pipes and hoses named by their route (for example compressor to condenser, or receiver drier to evaporator), A/C O-rings, a coupling, pressure switches and an ambient temperature sensor.

Air conditioning kits for the Classic Defender. Kits are titled for the 300Tdi and the Td5, both LHD, and a TDCi retrofit kit and a front air conditioning kit are also listed. Check the individual listing for what each kit includes and which drive side it suits.

Buying guide: Genuine, OEM and aftermarket heating and air conditioning parts

Budget Parts lists Genuine, OEM and aftermarket options in this collection. The available quality tier varies by part, so check the individual product listing when comparing options.

Ordering separately. A/C O-rings, receiver driers, heater seals, blower resistors and heater control knobs are listed as separate parts. Check the individual listing for what is supplied with a part.

Before you order

1. Start with the vehicle model and engine. Then use the model year or VIN where a part changed during a generation.
2. Check the drive side. Many blower motor titles state LHD or RHD, some heater controls and the heater-to-bulkhead seals are listed separately for LHD and RHD, and some heater matrices, heater assemblies and A/C parts carry LHD in the title.
3. Check whether the vehicle has air conditioning. Some heater matrices, and one heater assembly, heater pipe kit and blower speed resistor, carry A/C or Air Con in the title.
4. Read the title and the listing description. Matrix pipe layout, output and A/C use, a heater valve with or without its bracket, and whether a blower motor comes with its fan can be stated in either, so check both before ordering.
5. Check the A/C service parts for your model. A/C O-rings and receiver driers are listed separately. For the Defender 300Tdi only, the workshop manual says the receiver/drier must be renewed whenever the refrigerant system is opened; other models follow their own workshop manual.
6. Quote the VIN with any fitment enquiry. Give the full VIN or chassis number exactly as it appears on the vehicle. It lets a part number that changed mid-generation be checked against your vehicle.
