CONDITION SUMMARY:
SITUATION:
One or more of the following Air Conditioning (A/C) system symptoms may be evident:
https://topix.landrover.jlrext.com/topix/service/document/858853
11/28/2017
Page 3 of 18
• Vent temperatures 'cycle' (blowing warm and then cold);
• Windshield, rear window, and/or door windows mist up in cool (15°C or lower) ambient
temperatures;
• Poor cooling performance of the Air Conditioning (A/C) system; and/or
• Warm, damp or musty smells coming from the vents.
CAUSE:
This may be caused by the low pressure recorded on the high pressure system; high pressure
recorded on the low pressure system; A/C compressor clutch (where applicable) not working
properly; and/or A/C compressor electronic control valve worn out or sticking.
ACTION:
Should a customer express this concern, follow the appropriate Diagnostic Procedure -- 'A' or
'B' -- and, if necessary, Service Instruction outlined below.
