After the 10 mins i expect the a/c to get cooler, but of course not. then 20............30.........40 mins go by and i feel like im dyin. so i turn of the a/c......................
THE PROBLEM:

If it's a whistle accompanied by a chemical/oily smell, you got a leak in the system. R134a has a sweet/petroleum like smell to it. Did you notice a RPM jump as the compressor clutch was disenaging?

I would suggest having the system pressures checked by a good A/C repair shop in your area. Your freon charge may be a little low, needing an add without over charging. They have the equipment to check for leaks and bring your system back to normal...
