Hi, I'm Chad ,Welcome To JustAnswer, I'm reviewing your question and I will be be posting a replay ASAP

Expert:  Chad Farhat replied 3 months ago.

1- have you checked a/c Freon levels

2- there is several things could cause that ,fuses, a/c compressor relay ,a/c clutch relay , a/c control module in the dash .a.c pressure switch etc..

let start with free on, if low and system has 25 % or less it want engage ?

did you loose it suddenly or slowly lost the cooling and then ac compressor quit ?

Please let me know

suddenly quit
Expert:  Chad Farhat replied 3 months ago.

ok

what is the mileage on it ?

can you check Freon levels you will need a set of ac gauges to do that and let me know if system is full ?

and check fuses in the underhood fuse box ?

Customer: replied 3 months ago.
I have an idiot color coded gauge that says its just below the ok line. checked fuses under hood in one location is there another. Cooling fan comes on interior fan comes on. Is there a separate fuse for the compressor?
Customer: replied 3 months ago.
It has 130000 miles and the compressor was replaced by Honda 2005
Expert:  Chad Farhat replied 3 months ago.

fuse #1 in the under hood box 20 AMP ,LABELED AC COMPRESSOR CLUTCH / AC CONDENSER RELAY

ALSO A/C COMPRESSOR CLUTCH RELAY # 2 LABELED IN THAT FUSE BOX

I have sent you the diagrams below

check the a/c compressor clutch relay # 2 on the diagram i sent you ,you can replace it with another just to try if it makes compressor comes on ?

IS THE BLOWER MOTOR INSIDE THE CABIN STILL WORKING ?

Please let me know

Customer: replied 3 months ago.
cabin fan comes on. did a swap on relays. The idiot gauge is now indicator. Can I charge the unit without the compressor running?
Customer: replied 3 months ago.
that's low indicator
Expert:  Chad Farhat replied 3 months ago.

we have to confirm system is charged first , you can try jumping the pressure switch and see if compressor kicks in , while you are shooting the Freon thru the can deal you buy from advance auto

but if not , you will need an ac machine ,to recover evacuate & pull a 45 min vacuum , and recharge system complete with machine your compressor dont have to be on

I need to go pick some up Ill get back to you if that's ok
Customer: replied 3 months ago.
