Diagnosing Aircon Problems

This 'might' be the sequence, but it's been a long time.
Make sure the following first.
Ignition on (do not start engine)
Aircon 'ON'
Fan(s) OFF
A/C set to cold
Switch ignition on (again no start engine)
Press and hold the recirculation button and at the same time press the rear demister five times.
When the air starts moving around the cabin the recirculation light should flash a number of times if there is a fault, or not at all to show everything is running well.
Number of flashes determines the fault present.
I'm not sure if multiple faults show up sequentally, or you have to fix one before getting another fault flash.
