I made my living repairing and servicing car air conditioning for about 8years....but have now retired. Firstly the visual check....find the gas condenser which is mounted ahead of the cooling radiator...looks a bit similar....check for any oily looking patches....these will be where the aircon gas has escaped and taken some of the compressor lubricant out with it. If it looks dry and serviceable find the pressure switch,which is likely to be on the ali pipework going across the bulkhead...might involve lifting the plenum chamber plastic cover.Check again that it's dry. Check the compressor next...if the two terminals are easy to get to apply 12volts and observe the clutch plate on the end of the compressor coming together to give it drive,either polarity.If the clutch draws in with a click try it with the engine running. Now to add the gas to increase the efficiency......engine and system cold....feed gas through the low side port...the smaller one...until the a/c system has equal pressure with the can.When gas stops flowing turn the can off. Start the engine.....call for full fan and full cold....the econ button turns the system OFF. Watch the pressures increase and monitor the inside temperature.Soon observe the additional cooling fan come on either half or full speed. When the systems settled...2-3 minutes allow more gas to be drawn in through the low side until you have good cooling......do not over gas because over pressure is sure to find any leakages.
