Air Conditioning System Performance Check
WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- Normal pressures for a correctly charged and working system are 1.0 bar to 2.0 bar (low pressure system) and 11.0 bar to 15.0 bar (high pressure system).
- Make sure the air conditioning settings are as follows before performing the steps below:
- Set the system to recirculate. Set the left and right side temperature to low and blower direction to face and feet.
- Set fan speeds to max.
- Make sure all doors, windows and tailgate are closed.
- Make sure all vents are open, with no objects blocking the vent exits.
- Make sure that there is no debris in the air conditioning charging ports before connecting the air conditioning station.
When a failure symptom has been reproduced, refer to the symptom chart. After completing a repair, the air conditioning performance check should be repeated to confirm that the repair is successful.
- Connect the air conditioning station to the vehicle charging ports
- Close the valves on the air conditioning station
- Check the standing pressures of the air conditioning system. The system should not have been run for 20-30mins
- Close all doors, windows and tailgate
- Start the engine
- Set the temperature to the lowest setting (all zones)
- Set the blower speed to maximum
- Set the recirculate switch to on
- Set the air conditioning to on and check that the air conditioning compressor clutch engages and that the gauges register a change in pressure
- Raise engine speed to 1500rpm and maintain this speed for 5 minutes
- Check the pressure gauge readings
