Inspection and verification (Freelander 2)

CAUTION: Diagnostics by substituting a component from another vehicle is NOT permitted. Substituting control modules does not guarantee confirmation of the fault and, in addition, may cause additional faults in the vehicle being tested and/or in the vehicle from which the modules are removed.

1. Visually inspect for obvious signs of damage and system integrity.

Mechanical factors	Electrical factors
Cooling fan Control flap(s) Air duct(s) Deflector grille(s) Cabin Air Purification Filter Hose(s) Coolant pump Fuel fired auxiliary heater Fuel pump for fuel fired auxiliary heater Fuel lines for fuel fired auxiliary heater	Compressor Cooling fan Executive devices Microclimate control panel

2. Listen for any unusual noises when the climate control system is operating.

3. Inspect the refrigerant system with a UV lamp for traces of UV-sensitive dye to detect leaks.

4. If an obvious cause for the problem you identified or the customer described is found, correct it (if possible) before moving on to further actions.

5. If the cause is not visually obvious, check the climate control module, engine control module (ECM), fuel fired booster heater, and central junction box (CJB) for DTCs and refer to the Index diagnostic trouble codes (DTC).
