My A/C compressor clutch wont engage, but when power is shot to it, it engages. Wont stay on by itself so it just blows hot air.

Welcome to 2CarPros.

If the pressure in the system is too low or high, the compressor will not actuate. Have you checked Freon levels?

Here are a few links that may help:
