Air conditioning works fine for about 20 to 30 minutes and then the air gets warmer. I had the auto button on and checked the compressor and the clutch was engaged. Shut the Auto off and the clutch disengaged. Is the Temp. sensor on the switch not working or what? I appreciate any help due to I am unemployed right now. thanks

I would suggest starting with a test on the pressure readings, both high and low side. Lack of freon can cause this.
