Most likley its low"But it could also have a bad expantion valve?Is there any pressure on the system?If its cycling to fast its probley low"If its cycling normaly it could be a bad compressor" stopped up accumulator or exp valve.If you have access to a recovery machine it will help to know how much freon was in the system.HTH
PS: Do not overcharge! It can lock up ac comp or damage it!Also If you dont know what your doing find someone that does.

yep, you will see that the pulley is turning on the outside all the time but the center only turns when the ac is on. The click you hear is the sound caused by the electromagnetic effect created when voltage is applied to an internal coil within the ac clutch and it locks the center part of the pulley/clutch assembly to the outer. When the compressor is not running, the outer portion serves as an idler. When you stand in front and look at the pulley/clutch, the center should be not turning unless someone turns the ac on. Then it should make a click sound as the magnet engages the center to the outer and begins to turn.
Be sure the center does turn when the ac is turned on.
Another thing that can make it not feel cold is if air has gotten into the system. this makes the freon very inefficient and it will not cool as it normally would. Have the entire system evacuated, checked for leaks, test all components, then recharge.
2. the pressure switch on the accumulator is bad or
3. The clutch on the compressor is bad.
Look at the accumulator. It is the can sitting vertically in front of the ac/heater box on the passenger firewall. See the connector on the fender side with two wires going to it? Pull it off and put a piece of wire across the two female connectors in the plug. If the compressor clicks on and starts to run, you know it is either 1. or 2.
Probably number one but I just had number two fail on one of my cars.
If it does not run, look under the compressor and be sure the connector is plugged into the the back of the clutch.....
DO NOT LET IT RUN FOR MORE THAN A COUPLE OF SECONDS WITH THE WIRE JUMPING THE CONNECTOR AS THAT PRESSURE SWITCH IS A SAFETY VALVE TO PREVENT THE COMPRESSOR FROM OVERHEATING AND DESTRUCTING IF THE SYSTEM IS LOW ON FREON.
