How? How is the air co supposed to cool with no freon? The defrost function will work but no cooling the fuel...

Hi John, If the gas has gone the oil would still be in the compressor so would not do any harm if the system is not used. If you have a gas leak it is unlikely that the oil will seep ou as well without being seen.
The compressor will only work if there is gas, No gas no compressor, no air con. Even if you select it the system will not operate.

Hi Roger , I can understand your thinking mate and you are right that most of the oil does stay in the system and around 6 - 7 fl oz remain in the compressor sump when the system is turned off but , to use an analogy , it is like having oil in your engine sump and no oil pump when there is no gas .As far as using heating my understanding of the Jag is that to maintain the heat setting selected , that in combination with the water valve and by blending ambient air and hot air through the A/C system flaps the temp is maintained however if that is not sufficient the compressor will come on unless the heater is on maximum high temp and not on climate control. Roger just had a light bulb moment once again you are right that if there is a safety switch the comp should not come on My Model (78) does not have a safety switch usually on the receiver /drier perhaps the later models may? which will stop the comp from running. It still will need to be evacuated new Receiver drier and recharge to avoid the valves within the comp corroding , I don't think I made that very clear in the last post. I might add that I have never been able to find an oily patch when servicing a/c's many years ago . just a little tip when checking for leaks , using diluted detergent on the fittings is a common and effective way to find leaks but also cover the entire length of the hoses and look carefully for fine bubbles where the gas permeates through the hoses the only solution is replacement hoses or very regular topping up at the least.

Removing the connection to the comp via the magnetic clutch will stop it from working , it will not stop it from corroding not just the comp but the whole cooling system , I believe compressors are less expensive in your part of the world but even so ! .For those that live in a warm to hot climate where cooling is a must and might be reading this thread , my advice stands get it looked at or DYI if you can , I know that refrigerant is available in the USA in small cans for top up if that's all that is required .I guess this is a personal choice but if its in the Jag I like it to be working the way it's meant to be......John
