This happened to me before a couple of times and it turned out that my husband sat in the passenger seat with his long legs and kicked the rod out of the hole that turns the vent from heat to ac. If you look up under the dash on the passenger side, you will see a gold rod that controls what I would call the damper. If that has come out of the hole that turns the damper from heat to ac, judt put it back in the hole where it belongs and it should start working again. I wish I could ecxplain it clearer. If when you are up under there looking and turn the switch from heat to ac and vice cersa, you should see the rod move, but you won't see it change the damper position.

There may be a small hole or cut in a vacum line or possibly just loose. Also make sure the air filter box and the big hose to it are secure and clamps etc are tight. Pulleys and belts can make a high pitch sound also.

Are you sure the noise is coming from the compressor and not the belt tensioner or other accessories, when you turn the ac on it put more of a load on the engine. If not since the compressor was changed twice was it properly oiled and the clutch turned manually to insure proper lubrication. I am hoping if it is the compressor that the reciever dryer and expansion valve was changed and the ac system was flushed well, to insure no contamination, or blockage damaging the new compressor.

It's the clutch or compressor or the idle pulley for the belt for the AC to check it have someone start it with the hood open and use a broom handle pressed to your ear and put the end of the broom near the ac compressor and turn it on and see if you here it there then shut it off and check near the idler pulley to see if it's there. The stick acts like a doctors stethoscope and amplifies the noise and will allow you to pinpoint the noise more accurately. If it is the clutch it can be replaced without replacingthe whole compressor but you will have to buy it at JC Whitney on line. Many who sell them charge as much as the compressor assembly costs.

Did you install a new thermostat and make sure to bleed all the air out of the system when you replaced the radiator? If you didn't, or installed a Stant thermostat, replace it with a FACTORY OEM thermostat. Make sure the cooling system is bled by opening your radiator cap (WHILE THE CAR IS OFF AND COLD), starting the car and running the heater. Add coolant to the radiator as the engine heats up, until is at normal operating temperature AND starts spitting coolant back out.
Hope this helps,
