The A/C compressor clutch will not engage. It has rear air and there are no visible leaks. I have tried to see if it is getting power and checked relays and fuses looks to be fine but it does not seem to be getting power.

Good morning.

The first thing you need to check is the Freon. The system needs at least 20 lbs on the low side for the compressor to engage.

Do you have a gauge to check the pressures?
