Hi I have a chevy 2000 s10 my air conditioning stop working it doesn't blow cold air, I tried to fill the system, but it would take any freon. The gauge reads that its full, it blows air but when I turn the ac on, the ac pump doesn't turn on

Have you checked the fuses to make sure none are blown?

There are several pressure sensing switches that control and also protect that A/C system. You will need to test for power at the clutch connector to make certain power is getting to where it's needed.
If you have power at the clutch when the system should be running, but the compressor clutch isn't coming on, you need to replace the clutch and hub together.
