Just replaced ac compressor, dryer, expansion valve. also temp sensor for cooling system and thermostate. check engine lite now on .
SOURCE: The ac in my 95 Jetta just works while the car is cool, then it stop
In addition to what emission wiz says, observe the speed of the fan when you turn on the a/c. some fans, when the are cold they run faster, then they get hot and slow down a lot. Also check that the small belt that drives the second propeller is ok. And for last, check that the front of the radiator is clear of any garbage, like a plastic bag that might have been cought in front of the condenser with the wind. If all this is working properly, there is nothing else that could be happening machanically to this a/c to stop it from cooling. look at the center of the pully of the compresor, make sure the entire thig is spining when clutch engages.

something not right here ,firstly why didnt you just renew the clutch instead of a complete compressor ?? secondly do you have a machine to recharge the system and if so are you using it correctly ,the reason i ask is because in the machine the low and high pressure pipes are interconnected in the body of the machine so yes it would show these pressures.When refilling a car once machine has weighed the gas leaving the bottle shut off the red line and start engine leaving the blue line connected ,run engine at 2000rpm with A/C on full for about 3 mins to draw the gas in from the machine .Then close blue line and and do a recovery to see how much gas was left in the machine.Also did you put compressor oil in when you re fitted the compressor about 100cc is enough ,this is better put in directly into compressor ,then vacumn to about -750mg or a stage one vac pump and omit the oil recovery cycle .When running the air temperature coming out should be about 7.5centigrade is good but some cars will drop to 5C anything below 9C is ok ,and forget to clean out pollen filter
