Urgent help Please before the morning!!!

Hi Guys,
To cut the long story short, before this evening my air con compressor was working fine but had no gas in my aircondition system in my VS Calais, but as soon as the mechanic put the gas in the air con system it started to cool the air and then all of a sudden the compressor kicked out then kicked back in and vise versa.

Basically the compressor only kicks in when it feels like it and the mechanic said it could be the compressor which will cost me $700.

I'm hoping its not the compressor, could it be a TX valve or a orificle valve? if yes how much do the valves cost or what else could be causing the compressor to turn on then shut down then turn on then shut down again?

Any help would be great please, because l have an appointment ifirst thing n the morning if you guys can help me out that would be great so when l rock up l can let him know l'm not a noob...

thanks guys!!!!

Sorry mate..AC is not my thing.. Mind it does sound like it's becoming over pressured and cycling. Apart from that I sadly can't supply further info.

should l try and take some gas out of the pipe? hence it will reduce the pressure?
