Hello welcome to just answer I am master tech and will be able to assist you

so if i understand you correctly.

the fans turn on but the compressor does not come on correct.

do you have a volt ohm meter?

Customer: replied 4 months ago.
Expert:  MASTER TECH replied 4 months ago.

ok if you look at the a/c compressor you will see the single wire going to the compressor.

unplug it and measure the voltage at the harness wise coming from the body side.

or back probe the wire and see if you have 12 v when you turn the key on and the a/c on

see if you have voltage or not.

Customer: replied 4 months ago.
No voltage on a test light
Expert:  MASTER TECH replied 4 months ago.

ok did you unplug the connector ?

if so make sure you check for voltage at the wire side not the compressor side.

Customer: replied 4 months ago.

Customer: replied 4 months ago.

Expert:  MASTER TECH replied 4 months ago.

the clutch relay is in the under hood fuse box.

Expert:  MASTER TECH replied 4 months ago.

you can remove another relay from the fuse box

Customer: replied 4 months ago.
Tired all of them
Customer: replied 4 months ago.
Small relay under dash not marked
Expert:  MASTER TECH replied 4 months ago.

ok that the wrong relay

the a/c relay is in the under hood fuse box only.

see the chart I posted.

Customer: replied 4 months ago.
Moved all relays to horn they all blew the horn
Expert:  MASTER TECH replied 4 months ago.

ok not sure if that was a good idea.

each relay will have different terminals.

if you use the chart I posted and remove that relay and swap it out with another black relay in that same fuse box.

Expert:  MASTER TECH replied 4 months ago.

lets just swap the a/c clutch relay only please.

also what are the system pressures at ?

Customer: replied 4 months ago.
The are all the same in that area
Expert:  MASTER TECH replied 4 months ago.

ok

how about the a/c pressures

Customer: replied 4 months ago.
Check the low side around 140
Expert:  MASTER TECH replied 4 months ago.

140?

whats the high side ?

Customer: replied 4 months ago.
Did not check
Expert:  MASTER TECH replied 4 months ago.

ok if you can find out.

I have a CRV in my stall so I will take a pic of the relays and post it.

also in the mean time see if you can get a accurate pressure readings on the low and High side,
