Where is the AC pressure switch? sorry bit of a newbie here.

Right/pass side of the cond - low/bottom.

As stated already. If you do not have continuity on the pins on the switch. Either the ac pressure is low or you have a bad switch.

If you have continuity on the pins...we need to do more tests.

Go to the common diy thread on top of the gen tech help forum. Under the 03-07 accords, there is a link to HVAC codes. This is simple to try. If you do or don't get a code, let us know.

I checked the voltage on the connection right adjacent to the radiator and it gave out 12v

Now test the A/C pressure switch for continuity (as poorman212 stated).

Use a continuity test light, ohmmeter, or multimeter to test for continuity between the pins on the switch.

so i tested both the terminals on the switch using a voltmeter and i got the beeping sounds. which i am assuming it closes the circuit.

I can only assume your "beep" means there is continuity.

Turn the key on and the AC and blower on, measure the voltage on the BLU/RED wire to body ground. What voltage are you getting.

So after months of messing with it... the problem is electrical. If i short the relay under the hood everything works fine. I have replaced all the relays and that has not fixed the issue.

But i Cant have the relay short 24/7 since it activates the clutch and that could drain my battery over night.

I just hope no one has these issues, especially during the texas summer.
