Just changed the ac compressor, expansion valve and dryer then charged system.... worked great until I stopped at an auto parts store for a few minutes, now the ac compressor won't come on and the system is full of freon. .... I also seen now the recirc light won't come on.
SOURCE: Where and how do you refill freon on a VW 2001 Jetta?
if the ac system was functioning under a vacuum (it should be), the can should have gotten cold, is there already pressure in the system before you tried ti fill? you have the correct connection if it had a blue cap. it sounds like a possable restricted oriface tube...the instructions will come with new part, USE CAUTION r-134 system repairs can be very dangerous, be sure to remove and store refrigerant before repair...good luck, marty

I would use the factory Power steering fluid. However as long as the fluid is Hydrolic oil G 002 000 you will be fine. Just take this referance number in and have your local parts store see if they can come up with comprable fluid to the VW power steering fluid
SOURCE: a/c in jetta blows hot air, its been charged, compressor comes on.
you need to have it diagnosed by a professional. These are complicated systems even to a trained tech. You may be over or under charged, have a clogged expansion valve, have a leak or many other issues. This model has a rcv refrigerant control valve inside the compressor which regulates the pressure of the compressor. If you notice the compressor never shuts off like conventional auto a/c's do the only time the clutch works is when you turn it on or off. Can be complicated.

at idle most a/c get warmer as they are not under load to circulate the freon at a rapid pace
changing the dryer is wasting your money won't change anything sounds to me as if there might be a vapour lock in the system. run the car for a week with a/c on max to fully circulate freon to see if the problem goes away if not go back to the shot tell them to check system with gauges on the high and low side to make sure that it infact is properly charged with the right amount and temp.
42-54 degrees is good

You may not be full of refrigerant... There is a low pressure switch that prevents the AC from actuating the clutch, and the reason is: IF there is not enough refrigerant, you will not be able to move oil through the system and you will have major damage...so no engauge...
Get the system checked, most likely there is a leak somewhere..
