freon, low pressure switch, or shim in the ac clutch.

For mine it was the shim. Bypassing the low pressure switch would make it turn on for a few seconds and then it would stop again. Sometimes romping on it to 3000+rpms would get it to kick in for a few seconds, then it would blow warm again.

Mine was doing this and when I hooked up the pressure gauge from autozone I could watch the pressure go up, it would turn on, the pressure would drop and in a few seconds the compressor would turn off. over and over again. Added 2 cans of the freon from autozone and now it works well.

Mine was doing the exact same thing... I added one large can of freon, works great now.

Could be other things, but you are most likely just low on freon, get a can or two and a gauge.
