Hi, I'm Chad. Welcome to JustAnswer. I'm reviewing your question and I will be posting your reply ASAP.

Expert:  Chad Farhat replied 7 months ago.

hey how are you

1- the ac compressor will not come on if the system has less than 25% of Freon in it

2- if you hook up the test gauges with ac off not running, what does the low side read , is at 100 psi ?

3- if the ac system is low , it will not kick in ,if you using the ac machine it will force the Freon in it ,but since no machine i m assuming u r using a Freon can to charge, you will have to jump the pressure switch or the compressor relay and jump it and get ac compressor running to help introduce Freon to system

4- you can try giving power to the system straight on compressor connector does compressor come on ?Please let me know

Thank You
