A/C turns on and off

[jsfordboy02]

My compressor turns on and off when it feels like it when the A/C isnt even on. I know that it may do this when low on freon when the A/C is on, but when I just have the vents on? or Even when I have the vents on and the heater going? Will running the defrost kit on the A/C, I know on some newer cars it will.

The A/C compressor cycles on every setting except the vent setting and the floor heat setting.

I kinda figured that, but IT DOES cycle on the vent and floor settings......
